Abstract:
The following article is designed to identify and examine sexuality-related issues frequently experienced among females with SCI. Some of the widespread barriers and myths associated with SCI and female sexuality are Identified, followed by prevalent physiological concerns of SCI on female sexuality, including intercourse, birth control, and pregnancy. Common psychosocial aspects of SCI and female sexuality such as asexual attitudes toward persons with disabilities and concerns about body image are also discussed. Current models used to successfully work with persons who are experiencing sexual dysfunction are examined, with special emphasis on common problems among women with SCI. A five-step framework that can be used by counselors for identifying and addressing specific sexuality concerns among women with SCI, including attracting a partner, dating, and developing and maintaining long-term relationships are discussed.

Abstract:
In this invited article, I present an inclusive theory of gender that clarifies its interconnections with gender identity, gender expression, and sexuality. To support this functionalist theory, I summarize findings from an extensive body of mixed methods research on lesbian, gay, bisexual, transgender, queer, and other (LGBTQ+) genders in the United States. I use a feminist-intersectional lens to empirically base and historically situate a theory of gender that is grounded in research of LGBTQ+ communities (butch, femme, bear, leathermen, transgender, drag queens, and family/house systems). I define genders as either sets of personal qualities within a culture associated with physiological sex or sets of qualities that evolve in reaction to limitations of existing genders. The evolution of genders functions to meet needs in four domains: (1) psychological: an experience of fit between a core aspect of self and a gender construct; (2) cultural: the creation of an LGBTQ+ culture that asserts sets of gender characteristics, which were denied and stigmatized within preexisting cultural norms; (3) interpersonal: the communicating of affiliation and status to enhance safety; and (4) sexual: an erotic embodiment of signifiers of these needs via an aesthetic that structures sexual attraction. I detail how each function affects identity, security, belonging, and personal and social values.

Abstract:
Background Behavioural and other aspects of sexuality are not always consistent. This study describes the prevalence and overlap of same-sex and other-sex attraction and experience and of different sexual identities in Australia. Methods: Computer-assisted telephone interviews were completed by a representative sample of 20 094 men and women aged 16–69 years recruited by landline and mobile phone random-digit dialling with a response rate (participation rate among eligible people) of 66.2%. Respondents were asked about their sexual identity (‘Do you think of yourself as’ heterosexual/straight, homosexual/gay, bisexual, etc.) and the sex of people with whom they had ever had sexual contact and to whom they had felt sexually attracted. Results: Men and women had different patterns of sexual identity. Although the majority of people identified as heterosexual (97% men, 96% women), women were more likely than men to identify as bisexual. Women were less likely than men to report exclusively other-sex or same-sex attraction and experience; 9% of men and 19% of women had some history of same-sex attraction and/or experience. Sexual attraction and experience did not necessarily correspond. Homosexual/gay identity was more common among men with tertiary education and living in cities and less common among men with blue-collar jobs. Many gay men (53%) and lesbians (76%) had some experience with an other-sex partner. More women identified as lesbian or bisexual than in 2001–02. Similarly, more women reported same-sex experience and same-sex attraction. Conclusion: In Australia, men are more likely than women to report exclusive same-sex attraction and experience, although women are more likely than men to report any non-heterosexual identity, experience and attraction. Whether this is a feature of the plasticity of female sexuality or due to lesser stigma than for men is unknown.

Abstract:
AbstractThe physiological age of adult males of seven mealybug species was measured in relation to the elongation of the male pair of the waxy caudal filaments. These filaments begin to emerge after eclosion and reached their maximum length from 29.4–46.6 h. The studied males were divided into three age groups, expressed as percentages of the total waxy caudal filaments length. Attraction to a sex pheromone source was significantly higher in the oldest male group (maximum filaments growth) compared with youngest one. Only the oldest male group copulated successfully; few of the younger males tested displayed 'courtship' behavior towards conspecific virgin females. The calculated duration of the sexually active phase of the adult male life cycle varied among species ranging from 34.4 to 46.6 h. There were marked variations in the strength of attraction to a pheromone source according to time of day. There was a continuous decrease in sexual activity from morning to evening. Our findings reveal clear maturation periods for adult males of the seven studied species. The long immature phase of the adult male mealybug is probably also related to several physiological processes that are needed to complete male maturation. The most noticeable change is the elongation of the waxy caudal filaments. However, mating may be performed at any time ambient conditions are suitable. Whereas male mealybug flight towards a pheromone source is restricted to a few hours, the male may continue mating activity throughout its sexually active period.

Abstract:
Sexuality is a complex concept that can be measured based on various aspects. Depending on the variable of interest, investigators may wish to focus on sexual behavior (activity), sexual orientation (attraction to a particular gender), or sexual identity (self-identification with a particular group of people). Further complicating the process is the fact that these aspects of sexuality are not always congruent with one another. Lesbian, gay, and bisexuals (LGB) are sexual minorities that have been identified as one of several groups that experience health disparities. For researchers working with the LGB population, properly identifying and defining which aspect of sexuality is of interest to the investigator is paramount in obtaining accurate outcomes.

Abstract:
AbstractWhat drives the human sexual response cycle? The human sexual response cycle is a highly complex phenomenon that encompasses many transmitters and transmitter systems centrally and peripherally. The endocrine system is also intricately involved in the brain and in the periphery organs. Integration of these systems is a function of the nervous system that ultimately produces a vast array of cognitive, emotional, physiological, and behavioral responses. Therefore, it is not surprising that a disturbance in even a single system will lead to dysfunction in one or more phases of the sexual response cycle. This article highlights the complex roles the aminergic system plays along with key hormones that are equally involved. The article also points out how rudimentary and fragmented our knowledge is in this field and how few controlled studies are available. The potential for development of specific agents that target selective sexual dysfunctions is exemplified in sildenafil, the first such agent ever to be brought to market.

Abstract:
[Truncated abstract]Judgements of physical attractiveness are thought to reflect evolved preferences for a high quality mate. The central aim of this thesis was to investigate the hypothesis that female preferences are adaptations for finding good quality mates and that faces and bodies signal honest information about mate quality. To date, most human mate preference studies have examined face or body attractiveness alone, and many have created stimuli using computer graphic techniques. Throughout these studies, I endeavoured to maximise the biological relevance of my studies by incorporating both face and body attractiveness, and using photographs of individual participants. Most research on attractiveness has focused on faces or bodies separately, while our preferences have evolved based on both seen together. A fundamental requirement of studying face and body attractiveness independently is that there is no interaction between the two. My first study confirmed that the face and body did not interact when an overall attractiveness judgment was made. I also investigated the independent contributions of rated attractiveness of the face and the body to ratings of overall attractiveness. Face and body attractiveness each made significant independent contributions to overall attractiveness in males and females. For both sexes, facial attractiveness predicted overall attractiveness more strongly than did body attractiveness, and this difference was significant in males. ... This study indicates that although current levels of T covary with male mating success, this effect may not be mediated by women's preferences for visual cues to T levels conveyed in static face or body features. The fourth study in this thesis investigated the phenotype-linked fertility hypothesis, which proposes that females obtain reliable information on male fertility from male expression of sexual traits. A previous study of Spanish men reported that facial attractiveness was positively associated with semen quality. I aimed to determine whether this effect was widespread by examining a large sample of Australian men. I also extended my study to determine whether cues to semen quality are provided by components of attractiveness: masculinity, averageness, and symmetry. I found no significant correlations between semen quality parameters and attractiveness or attractive traits. While male physical attractiveness may signal aspects of mate quality, my results suggest that phenotype-linked cues to male fertility may not be generalised across human populations. Together, these studies challenge current methodologies and theories of preferences for secondary sexual traits as honest signals of mate quality. The findings show that it is important to study human mate preferences in biologically relevant contexts, for example by using photographs of both faces and bodies, to maximise the real life application of results. In addition, the findings suggest that male attractiveness does not signal cues to testosterone or semen quality, although testosterone is associated with mating success. The implications of these findings and possible avenues for future research are discussed.

Full text
Abstract:
[Truncated abstract] The assumption that facial attractiveness signals mate quality is central to current evolutionary theories of human sexual selection. Evidence for direct links between attractiveness and mate quality is, however, scarce, and the exact nature of mate quality remains the subject of debate. Mate quality may include genetic diversity, because genome-wide diversity has been linked to individual fitness, and diversity within the Major Histocompatibility Complex (MHC) has been associated with immunocompetence and health in many species. This thesis investigates whether individual genetic diversity plays a role in human sexual selection. The main aim is to examine whether MHC diversity, compared to genetic diversity in general, is especially important for mate preferences, health and mating success. The four studies herein are based on data collected from a large sample of heterosexual, Caucasian males and females. Participants were photographed, provided a DNA sample, and completed questionnaires regarding sexual history and health. Genetic diversity was calculated as both mean heterozygosity (H) and standardised mean-d2 (d2), separately for 12 MHC microsatellite loci and 11 nonMHC loci. The photographs were rated for various attractive features by opposite-sex raters. The first study investigated whether MHC diversity influences preferences for facial appearance in a potential mate, and if so, are they specific to the MHC and are they mediated by specific facial characteristics? I found that MHC-H, but not nonMHCH, positively predicted male facial attractiveness, and that this relationship was mediated by facial averageness. For females, nonMHC-d2 predicted facial symmetry, and potentially attractiveness. These findings indicate that faces contain visual cues to mate quality in both males and females, providing support for evolutionary theories that our preferences are adaptations for identifying mates of high quality. ... Measuring them both allowed me to tease apart their effects on mate preferences, and on health and mating success. Indeed, the MHC appears to be especially important in sexual selection as MHC diversity predicted female mate preferences after controlling for nonMHC diversity, and MHC dissimilarity predicted male mate preferences after controlling for nonMHC dissimilarity. Moreover, although MHC diversity did not appear to influence males’ preference for females, it did predict female mating success, suggesting that males also attend to MHC-related cues, although perhaps non-facial cues, when seeking mates. Additionally, nonMHC diversity predicted both male preferences for female faces and health, suggesting that such preferences are adaptive. Importantly, by providing direct links between facial attractiveness and biological markers of individual quality, genetic diversity, these results support the commonly held assumption that facial attractiveness signals mate quality.

Abstract:

This study examined the effect of sweat exposure on sexual attraction in heterosexual and homosexual women. Strictly heterosexual and homosexual female participants were exposed to underarm pads containing sweat. Samples were collected during the Stimulus Preparation Phase from healthy, strictly heterosexual men and women. Women’s samples were collected on Day-14 and Day-27 of cycle, and men’s from any two days.

In the Stimulus Exposure Phase, the male sweat and Day-14 female sweat samples were the experimental conditions, and the no male sweat and Day-27 female sweat were the controls. During the exposure phase, sweat samples were hidden and participants completed two computer tasks. First, the key-press task had participants view or skip male and female photographs. Second, the rating-task had participants rate attractiveness of the male and female photographs. The ratings and viewing times were collected then analyzed.

Heterosexual women showed a strong preference for male photos over female photos only when exposed to male sweat. They also preferred female photos less than homosexual women when exposed to male sweat or Day-14 female sweat. Homosexual women showed a strong preference for female photos over male photos when exposed to male or female Day-14 sweat.

Homosexual women also preferred female photos more than heterosexual women when exposed to male sweat or Day-14 female sweat.

The findings of this study suggest that exposure to male sweat may enhance heterosexual women’s preference for men and exposure to female sweat from the ovulatory period of the menstrual cycle may inhibit the preference for women of heterosexual women. However, exposure to male sweat and female sweat from the ovulatory period may enhance the preference for women in homosexual women.

Abstract:
The scientific study of sex has developed significantly since the inception of psychophysiological methods to assess sexual arousal. Sexual psychophysiology involves assessing the physiological activation of the sexual response system, in addition to mental, behavioral, and emotional processes or experiences (Rosen & Beck, 1988). Measures of sexual arousal are reviewed in Chapter One. Chapter Two describes a study testing the validity of the most commonly used measure of genital arousal in women, vaginal photoplethysmography. Results indicate that vaginal photoplethysmography is sensitive to sexual arousal only, and that there are important sex differences in patterns of physiological arousal to sexual stimuli. Directions for future research are discussed.

Abstract:
In this thesis, I aimed to explore vocal attractiveness from an evolutionary perspective: how listener's preferences for vocal qualities of potential partners could increase mating success and reproductive success. Chapters 1-4 outline the background to the thesis, reviews acoustics, sexual selection theory, and human mate-choice. In chapter 5, I correlated attributions made to voices to the acoustic properties of the voices. In men's voices, pitch negatively predicted vocal attractiveness. Attributions of masculinity, size, age, health and vocal attractiveness were all positively correlated. In women's voices, pitch, formant dispersion and perceived health positively predicted vocal attractiveness. Masculinity, size and age negatively predicted vocal attractiveness. In chapter 6, I measured the effect of manipulating fundamental and/or formant frequencies (apparent vocal-tract length) on vocal attributions. Women found men's voices with lowered voice pitch and decreased formant dispersion more attractive, masculine, large, older and healthier. Women's size predicted preference for male vocal- tract length. In chapter 7, I explored attitudes to voices speaking vowels and whole sentences using a correlation design and acoustic manipulations. Women's self-rated attractiveness positively predicted vocal masculinity preferences. Most of the remaining studies focus on how hormones relate to vocal production and perception. Women with less oestrogen showed the biggest menstrual cycle shifts in vocal masculinity preferences, preferring masculinity most in the fertile phase (chapter 8). Men's testosterone levels predicted the size of changes in attributions of dominance to men's voices (chapter 9). Women's voice pitch correlated with facial-metric masculinity and facial attractiveness (chapter 10). Men preferred women's voices with raised pitch to lowered pitch at multiple levels of starting pitch (chapter 11). These findings indicate men preferred femininity to averageness. In chapter 12, I relate the work in this thesis to other work and the broader evolutionary perspective.

Abstract:
In economic games the facial attributes of counterparts bias decisions to trust and decisions to enter play. We report research supporting hypotheses that trust and reciprocation decisions in trust games are biased by mechanisms of sexual selection. Hypotheses that trust game behaviour is modulated by inter-sexual competition were supported. 1) Attractive individuals elicit more cooperation. 2) Male participants display trust and reciprocation toward attractive female counterparts in excess of perceived trustworthiness (and this display is modulated by male self-reported physical dominance). 3) Female participants appear to respond to male trust as a signal of sexual interest and are therefore more likely to exploit the trust of attractive males. 4) In explicitly dating contexts females are more likely to prefer attractive males to pay for the meal. These results indicate that participants are biased by mate choice and mating display considerations while playing economic games in the lab. Hypotheses that trust game behaviour is modulated by intra-sexual competition for resources were also somewhat supported. 1) Male participants reporting an ability to win fights with same-sex peers are more exploitative of other males. 2) Cues to current circulating testosterone level in counterpart’s faces are less trusted but elicit more reciprocation. 3) The male sexually dimorphic trait facial width-to-height ratio (a trait which is related to both aggression and dominance) is related to an increased proportion of decisions to exploit others in the trust game while also being used by others as a cue to untrustworthiness. We conclude that trusting and trustworthy behaviour in both sexes is biased by mating market considerations predicted by intra- and inter-sexual selection.

Abstract:
The human voice might have been shaped by sexual selection. Hence, voice fundamental (F0, or pitch) and formant frequencies (Fn, or timbre) are proposed to convey fitness cues germane to rivals and potential mates. First, I confirm the independent effects of F0 and Fn on listeners’ assessments of speaker size, masculinity, and attractiveness. Second, I quantify the just-noticeable differences in both vocal features and then place F0 and Fn cues in conflict by equally discriminable amounts to test their relative influence on such voice-based social judgments. Results revealed a greater relative role of Fn in listeners’ ratings of all three dimensions, suggesting that these dimensions might all be cued more reliably by Fn than F0. Alternatively, given post-hoc principal component analyses that revealed considerable overlap in ratings of size, masculinity, and attractiveness, listeners’ conceptions of these dimensions may not be independent despite a research tradition that assumes they are.

Abstract:
For humans and non-human primates (NHPs) the face represents a particularly important source of social information providing a means of conspecific recognition and cues to personal details including sex, age, and emotional state. The human face may also be fundamental in the transmission to conspecifics of other forms of socially relevant information including the display of facial traits associated with sexual attraction and mate choice. A wealth of experimental literature indicates that humans display robust preferences for certain facial traits associated with facial attractiveness including preferences for bilateral facial symmetry, facial averageness and sexually dimorphic faces and facial features. It is thought that these preferences have evolved via sexual selection, and may be adaptive, due to the role that these specific facial features play in reliably signalling to others the possession of heritable genetic quality or ‘good genes’. Therefore, from an evolutionary perspective, it is possible that certain facial preferences may represent an evolutionary adaptation for the selection of potential mate quality. However, despite similarities between human and NHP face processing and recognition abilities, the shared evolutionary history and social importance of faces to primates in general, and the potential importance of these preferences in the mate choice decisions of NHPs, very little research has investigated the extent to which NHPs display comparable preferences to humans for these specific facial traits. Consequently, the aim of the following thesis was to comparatively assess the general and more specific preferences that humans and NHPs display for faces and for traits associated with facial attractiveness. Data was compiled from preference studies examining the visual preferences displayed by two species of NHP (brown capuchins (Cebus apella) and chimpanzees (Pan troglodytes)) for conspecific faces manipulated for those facial traits associated with attractiveness, and from a single study of brown capuchins examining their general visual preferences for various types of facial information. Comparative preference studies were also conducted upon human adults and infants examining the visual and declared preferences that they display for manipulations of facial attractiveness. Data showed that despite possessing general preferences for certain faces and facial information, generally NHPs displayed no significant preferences for those facial traits thought to influences judgements of attractiveness in humans. Possible reasons for this absence of preference for these particular facial traits and the evolutionary implications of these findings are discussed.

Abstract:
In many behavioral paradigms, repeated exposures to a particular stimulus or event results in lower immediate early gene (IEG) expression. First, it was investigated if a similar reduction in IEG expression in the brain areas controlling male sexual behaviors would be observed after repeated copulation experiences in male Japanese quail. The results showed that IEG expression, as assessed by egr-1 immunoreactivity, did not increase in the POM, the BST, or the PAG after a copulation episode in highly sexually experienced subjects. One possibility was that the pattern of initial elevation of neuronal activity during the early trials of sexual interactions and the lack of increase in IEG expression later was associated with the novelty of sexual stimuli. While early exposures to certain stimuli constitute a new learning experience, the significance of such exposures would be lower as the level of experience increases. It was hypothesized that the introduction of a novel stimulus would increase the IEG expression in the POM, the BST and the PAG of experienced subjects. To evaluate this prediction, subjects were tested to see if they learn to respond to females decorated with distinct novel artificial cues after repeated exposures. The results showed that control subjects that did not have sexual experiences with decorated females discriminate against such females and directed their responses to normal females. Trained subjects did not show such preferences and responded to both types of females. In the next experiment, contrary to the prediction, no increase in IEG expression was observed after the introduction of the novel stimulus. This might be due to lower sexual motivation in subjects exposed to novel females. Effects of sexual experience were also tested in the catecholaminergic system. It was hypothesized that TH innervation in the POM and the BST would increase as a result of sexual experience. IEG expression in the catecholaminergic areas was predicted to be lower after repeated sexual experiences. The results showed no effect of experience in either tyrosine hydroxylase (TH) innervation, nor TH-egr-1 colocalization. These findings suggest that experience-related changes in male sexual behavior may be mediated by a different neurotransmitter system.

Abstract:
This study explores the intrapersonal and interpersonal ecological factors that influence adolescent females' perceptions of sex and the extent to which their perceptions of sex impact onset of sexual intercourse as they mature. Particular attention is given to how depression influences individual, personal and social factors in an adolescent female's life, to shape her attitudes towards sex, and determine her engagement in sex as she reaches young adulthood. Ecological Systems Theory is used to examine the extent to which individual, family, and social factors impact adolescent females' perceptions of sex and onset of sexual intercourse. Data are from the National Longitudinal Study of Adolescent Health. Multinomial logistic regression reveals that the factors associated with less positive perceptions of sex are age, self-esteem, sexual intercourse, religiosity and connection to mother and peers, as well as, depression in combination with religiosity and connection to one's peers. More positive perceptions of sex are linked with depression, connection to one's school, as well as, depression in conjunction with aging and sexual intercourse. Results from the logistic regression analysis determines that less positive perceptions of sex delay onset of sexual intercourse among adolescent females; however, adolescent females' attitudes towards sex vary greatly in determining onset of sexual intercourse as they mature. Furthermore, there is no association between depression and adolescent females' perceptions of sex in predicting onset of sexual intercourse as they progress into young adulthood. The findings from this study suggest that programs focused on shaping attitudes toward sex should assist young women in forming a definite opinion about their decision to have sexual intercourse or abstain from engagement in sexual intercourse. A female's age, sense of self-worth, emotional state, and religiosity as well as the strength of her relationships with parents, peers and school must be considered when addressing her sexual health. This investigation supports the use of Ecological Systems Theory as a useful theoretical framework for examining the factors that influence adolescent females' perceptions of sex and engagement in sexual intercourse. A more cognitive investigation of the relationship between depression and the factors in an adolescent female's life that influence her attitudes towards sex and how depression affects an adolescent female's perception of sex and her decision to engage in sexual intercourse is warranted as this study finds only minor support for the use of Ecological Systems Theory when exploring the association between depression and adolescent female sexual health.

Abstract:
Sexual dimorphism of the adult brain regulates sex-dependent functions including reproductive and neuroendocrine activities in rodents. It is determined by sex steroid hormones during a critical perinatal period in female and male rodents. Sex steroids act on each nuclear receptor in the brain and control different physiological and neuroendocrine functions and behaviors. Several regions of the brain show evident morphological sex differences that are involved in their physiological functions. This review addresses and focuses largely on the role of sex-dependent differences in the brain, and their crucial functions in animal models. Particularly, recent intriguing data concerning the diversity of neuronal functions and sexual dimorphism are discussed.

Abstract:
Blushing is unique to humans. So Darwin could not show it had evolved by studying its occurrence in animals. Neither do infants blush. Hence, unlike crying, it was not easily shown to be innate. Furthermore its triggers appear to be immaterial. Expression solves the problem of why and when people blush by hypothesizing a reflexive process of reading: I blush because I read you as reading and judging me—my appearance, or conduct. This dynamic of meta-recognition or self-attention requires the construction of a complex theory of human agency, involving: a dual self; the operation of innate sympathy; a physiological hypothesis; and an evolutionary derivation. Meta-recognition underpinned Darwin’s understanding of sexual attraction, group cohesion, and conscience. It also served as a formative influence on later psychologies of symbolic interaction.

Abstract:
Sexuality is a complex concept encompassing far more than the simple sexual act. Sexuality in fact includes the physiological, behavioural and relational aspects of human sexual life, which are variously influenced by psychological factors (e.g. sexual fantasies, desire, arousal, psychosexual orientation, and the choice of the sexual object), as well as social and organic (vascular, nervous, and endocrine) factors. From a functional point of view, a normal penile erection may be defined as an erection which permits the penetration of a lubricated vagina without additional assistance. Concerning the erectile mechanism, the haemodynamic changes in the penis require a high degree of central and peripheral nervous coordinated control and an unaffected endocrine system.

Abstract:
Puberty may be defined as the physiological process resulting in the attainment of sexual maturity and reproductive capacity. Puberty is an integral component of the evaluation and treatment of endocrine disorders in children and adolescents. Not only does it impact on sexual maturation, but it has other effects with lifelong consequences, including linear growth, changes in body composition, and skeletal mineralization. Patients with disorders of puberty, including precocious and delayed puberty, make up a large percentage of the children and adolescents who consult paediatric endocrinologists. An understanding of delayed or absent puberty requires a foundation in the normal processes regulating the onset of puberty, and factors essential for its progression and completion. In this chapter, we will first review the mechanisms of normal growth and puberty, particularly with regard to their interdependence. We shall then discuss the differential diagnosis of delayed or absent puberty, and present diagnostic algorithms for hypergonadotropic and hypogonadotropic hypogonadism, emphasizing some gender-specific aspects.

Abstract:
Trauma- and stressor-related disorders occur following exposure to a traumatic or other stressful event. They differ according to the timing of exposure and age at manifestation. Post-traumatic stress disorder (PTSD) develops following exposure to actual or threatened death, serious injury, or sexual assault. Intrusions, distressing dreams, dissociative reactions (flashbacks), intense psychological distress, and physiological stress responses at exposure to internal of external cues that symbolize aspects of the traumatic event are typical for PTSD. Behaviourally, PTSD reflects a strategy of defence involving avoidance, attentive immobility, withdrawal, aggressive defence, appeasement, and tonic immobility, some of which are ancient vertebrate heritage. These defence mechanisms are preceded by heightened vigilance and risk assessment. Persistent stress responses often occur when important biosocial goals had been thwarted by the traumatic event. Species with long life-history patterns may be more vulnerable to developing PTSD than species with short life cycles.

Abstract:
The previous chapter provided a detailed description of the currents underlying the generation and propagation of action potentials in the squid giant axon. The Hodgkin-Huxley (1952d) model captures these events in terms of the dynamical behavior of four variables: the membrane potential and three state variables determining the state of the fast sodium and the delayed potassium conductances. This quantitative, conductance-based formalism reproduces the physiological data remarkably well and has been extremely fertile in terms of providing a mathematical framework for modeling neuronal excitability throughout the animal kingdom (for the current state of the art, see McKenna, Davis, and Zornetzer, 1992; Bower and Beeman, 1998; Koch and Segev, 1998). Collectively, these models express the complex dynamical behaviors observed experimentally, including pulse generation and threshold behavior, adaptation, bursting, bistability, plateau potentials, hysteresis, and many more. However, these models are difficult to construct and require detailed knowledge of the kinetics of the individual ionic currents. The large number of associated activation and inactivation functions and other parameters usually obscures the contributions of particular features (e.g., the activation range of the sodium activation particle) toward the observed dynamic phenomena. Even after many years of experience in recording from neurons or modeling them, it is a dicey business predicting the effect that varying one parameter, say, the amplitude of the calcium-dependent slow potassium current (Chap. 9), has on the overall behavior of the model. This precludes the development of insight and intuition, since the numerical complexity of these models prevents one from understanding which important features in the model are responsible for a particular phenomenon and which are irrelevant. Qualitative models of neuronal excitability, capturing some of the topological aspects of neuronal dynamics but at a much reduced complexity, can be very helpful in this regard, since they highlight the crucial features responsible for a particular behavior. By topological aspects we mean those properties that remain unchanged in spite of quantitative changes in the underlying system. These typically include the existence of stable solutions and their basins of attraction, limit cycles, bistability, and the existence of strange attractors.
