Abstract:
Abstract Electroencephalographic (EEG) frontal alpha asymmetry (FAA) has been associated with differences in the experience and expression of emotion, motivation and anger in normal and clinical populations. The current study is the first to investigate FAA in alcohol-related intimate partner violence. EEG was recorded from 23 distressed violent (DV) and 15 distressed nonviolent (DNV) partners during a placebo-controlled alcohol administration and emotion-regulation study. The State-Trait Anger Expression Inventory 2 was used to evaluate anger experiences and was collected from both participants and their partners. During baseline, acute alcohol intoxication DV partners had significantly greater right FAA, whereas DNV partners showed greater left FAA. Both partner types demonstrated significantly greater right FAA during the placebo beverage condition of the emotion-regulation task when viewing evocative partner displays of contempt, belligerence, criticism, defensiveness and stonewalling, but greater left FAA during acute alcohol intoxication. Although no group differences were found in the emotion-regulation task, partner self-reported anger experiences accounted for 67% of the variance in the FAA of DV participants when intoxicated and viewing evocative stimuli, suggesting dyadic processes are important in understanding alcohol-related IPV. These findings suggest that FAA could index the affective and motivational determinants through which alcohol is related to IPV.

Abstract:
ABSTRACTBackground: Depression, despite being the most common of mental illness lacks any quantifiable and absolute biomarker. Frontal alpha asymmetry (FAA) is proposed as biomarker of depression both in resting and activated state. Yet, the location of extraction of alpha, clinical utility as well as validity of FAA is uncertain. With aim of obtaining clarity on this confusion we conducted this study. Methodology: Electroencephalographic frontal alpha power was calculated in patients of depression (n = 24) and compared with healthy controls (n = 17) for the assessment of FAA. Both groups were studied for resting phase and activation phase changes in FAA. For activation phase, auditory stimuli in the form of Indian classical music were used. Results: Frontal alpha power was measured across FP1, FP2, F3, F4, F7, and F8. Mean powers were compared in resting (before), activated (during) and postactivated resting stage (after). FAA was statistically significant in F7–F8 pair of electrodes and on F7 electrode when compared between cases and controls. Conclusion: Quest for biomarker for depression churned out FAA as frontrunner. Despite of vast amount of research on it, practical utility eludes us. We need to revisit our approach from conventional search of the diagnostic biomarker; as FAA might reflect component of depression but not totally disorder. In our opinion, we are not yet ready for it and have a road ahead to travel.

Abstract:
Reduced left-lateralized electroencephalographic (EEG) frontal alpha asymmetry (FAA), a biomarker for the imbalance of interhemispheric frontal activity and motivational disturbances, represents a neuropathological attribute of negative symptoms of schizophrenia. Unidirectional high-frequency transcranial random noise stimulation (hf-tRNS) can increase the excitability of the cortex beneath the stimulating electrode. Yet, it is unclear if hf-tRNS can modulate electroencephalographic FAA in patients with schizophrenia. We performed a randomized, double-blind, sham-controlled clinical trial to contrast hf-tRNS and sham stimulation for treating negative symptoms in 35 schizophrenia patients. We used electroencephalography to investigate if 10 sessions of hf-tRNS delivered twice-a-day for five consecutive weekdays would modulate electroencephalographic FAA in schizophrenia. EEG data were collected and FAA was expressed as the differences between common-log-transformed absolute power values of frontal right and left hemisphere electrodes in the alpha frequency range (8–12.5 Hz). We found that hf-tRNS significantly increased FAA during the first session of stimulation (p = 0.009) and at the 1-week follow-up (p = 0.004) relative to sham stimulation. However, FAA failed to predict and surrogate the improvement in the severity of negative symptoms with hf-tRNS intervention. Together, our findings suggest that modulating electroencephalographic frontal alpha asymmetry by using unidirectional hf-tRNS may play a key role in reducing negative symptoms in patients with schizophrenia.

Abstract:
OBJECTIVES/SPECIFIC AIMS: The current study is the first investigation of frontal alpha asymmetry in distressed violent (DV) and distressed nonviolent (DNV) partners during a placebo-controlled alcohol administration and emotion-regulation study. Because this is the first study of the pharmacological effects of alcohol on FAA, the first portion of the study was conducted to characterize alcohol effects in DV and DNV partners during the baseline condition. The subsequent portions of the study were conducted to characterize the effects of alcohol and evocative stimuli on FAA in DV and DNV partners. We hypothesized that DV partners would demonstrated greater left frontal alpha asymmetry when intoxicated and viewing evocative partner stimuli than DNV partners. Lastly, we attempted to replicate previous research that has found associations between baseline measures of FAA and the State-Trait Anger Expression Inventory – 2 (Spielberger, 1999) subscales of Trait Anger, Anger Expression-Out, Anger Expression-In, Anger Control-Out, Anger Control-In (Hewig, Hagemann, Seifert, Naumann, & Bartussek, 2004). METHODS/STUDY POPULATION: Partners in the present study were drawn from a larger study investigating over-arousal as a mechanism between alcohol use and intimate partner violence (AA022367). Couples were recruited from the community via radio, television and newspaper advertisements, and eligibility screening occurred at the couple level. Participants included in the present analysis were 23 DV partners (12 female, 11 male), and 15 DNV partners (7 female, 9 male). The mean age of the sample was 32 (SD 4.8 years, range 23-40 years). Data from two DV partners were not included in the analyses of the FAA in the emotion-regulation tasks due to movement artifacts during the alcohol condition leaving too little data for analysis. RESULTS/ANTICIPATED RESULTS: The expected beverage by couple type interaction did not reach significance [F (1, 36) = 3.93, p = .055], but the between-subjects effects of couple type revealed a significant difference [F (1, 36) = 4.425, p = .042]. Contrary to our hypothesis, however, these results suggest that under conditions of alcohol, DV partners evidenced significantly greater relative right frontal alpha power asymmetry whereas DNV partners evidenced greater relative left frontal alpha power asymmetry. Although there was no significant between-subjects effect, there was a nearly significant interaction between beverage type and emotion regulation condition [F = (1, 36) = 4.032, p = .052] and a significant main effect of emotion regulation condition [F (1, 36) = 7.579, p = .009]. It appears that asking the participants to “not react” to their partners’ evocative stimuli caused significantly greater right frontal alpha asymmetry. Because intimate partner violence is best understood in the context of conflict between two partners, we also examined partner-reported experiences of anger as predictors of DV participant’s FAA. The model as a whole predicted 67.4% of the variance in DV partner FAA, R squared change =.674, F Change (5, 15) = 6.21, p = .003. Three anger experience scales were statistically significant. The partner Anger Control-Out (B = -1.23, p =.001) scale recorded a higher standardized beta value and accounted for 40% of the variance in this model. Anger Control-In (B = .63, p = .022) accounted for 14% of the variance in the model, and Anger Expression-Out scale (B = .57, p = .024) accounted for 13.7% of the variance in the model. DISCUSSION/SIGNIFICANCE OF IMPACT: The current study is the first pharmacological study of the effects of alcohol on frontal alpha asymmetry in distressed violent and distressed nonviolent partners. Contrary to our hypothesis, under acute alcohol intoxication during the baseline condition, DV partners exhibited significantly greater relative right FAA compared to DNV partners who exhibited significantly greater relative left FAA. Because intimate partner violence is best understood in the context of couple conflict, we examined the ability of partners’ anger experiences to predict DV and DNV partners’ FAA, and a very interesting pattern emerged among our DV participants and their partners. The anger experiences of our DV participants’ partners accounted for 67% of the variance in the FAA of our DV participants when they were intoxicated and viewing evocative stimuli.

Abstract:
To better understand the biopsychosocial mechanisms associated with development and maintenance of cannabis use disorder (CUD), we examined frontal alpha asymmetry (FAA) as a measure of approach bias and inhibitory control in cannabis users versus healthy nonusers. We investigated: (1) whether FAA could distinguish cannabis users from healthy controls; (2) whether there are cue-specific FAA effects in cannabis users versus controls; and (3) the time course of cue-specific approach motivation and inhibitory control processes. EEG data were analyzed from forty participants (CUD (n = 20) and controls (n = 20)) who completed a modified visual attention task. Results showed controls exhibited greater relative right hemisphere activation (indicating avoidance/withdrawal motivation) when exposed to cannabis cues during the filtering task. By contrast, cannabis users exhibited greater relative left activation (approach) to all cues (cannabis, positive, negative, and neutral), reflecting a generalized approach motivational tendency, particularly during later stages of inhibitory control processes. The difference between cannabis users and controls in FAA was largest during mid- to late processing stages of all cues, indicating greater approach motivation during later stages of information processing among cannabis users. Findings suggest FAA may distinguish cannabis users from healthy controls and shows promise as a measure of inhibitory control processes in cannabis users.

Abstract:
Frontal alpha asymmetry (FAA) has been associated with emotional processing and affective psychopathology. Negative and withdrawal stimuli and behaviors have been related to high levels of right cortical activity, while positive and approach stimuli and behaviors have been related to increased left cortical activity. Inconsistent results in terms of depressive and anxious symptoms and their relationship to FAA have been previously observed, especially at older ages. Additionally, no studies to date have evaluated whether loneliness, a negative feeling, is related to FAA. Therefore, this study aimed (i) to compare FAA between younger and older adults and (ii) to investigate the possible relationships between loneliness, depressive and anxious symptomatology with FAA in young and older adults. Resting electroencephalogram recordings of 39 older (Mage = 70.51, SD = 7.12) and 57 younger adults (Mage = 22.54, SD = 3.72) were analyzed. Results showed greater left than right cortical activity for both groups and higher FAA for older than younger adults. FAA was not predicted by loneliness, depressive or anxious symptomatology as shown by regression analyses. Findings bring clarity about FAA patterns at different ages and open the discussion about the relationship between negative emotional processing and frontal cortical imbalances, especially at older ages.

La recherche de biomarqueurs des troubles affectifs apporterait une meilleure compréhension des mécanismes sous-jacents et améliorerait la prise en charge.

Abstract:
Previous research found that the parental autism phenotype is associated with child autism spectrum disorder (ASD), even if the pathway between autistic traits in parents and child ASD is still largely unknown. Several studies investigated frontal asymmetry in alpha oscillation (FAA) as an early marker for ASD. However, no study has examined the mediational effect of FAA between parental autistic traits and child ASD symptoms in the general population. We carried out a prospective study of 103 typically developing infants and measured FAA as a mediator between both maternal and paternal autistic traits and child ASD traits. We recorded infant baseline electroencephalogram (EEG) at 6 months of age. Child ASD symptoms were measured at age 24 months by the Child Behavior Checklist 1½–5 Pervasive Developmental Problems Scale, and parental autistic traits were scored by the Autism spectrum Quotient questionnaire. The mediation model showed that paternal vs. maternal autistic traits are associated with greater left FAA which, in turn, is associated with more child ASD traits with a significant indirect effect only in female infants vs. male infants. Our findings show a potential cascade of effects whereby paternal autistic traits drive EEG markers contributing to ASD risk.

Abstract:
Frontal encephalographic (EEG) alpha asymmetry has been proposed as a measure of the relative difference in average cortical activity between the right and left anterior cortex, where this difference is taken as a physiological marker of trait and state level variables associated with affect. The validity of asymmetry as an indicator of both physiological and psychological variables is in part determined by the psychometric properties of asymmetry scores. The present studies focus on the psychometric assessment of frontal alpha asymmetry measured during rest. The first study involves a novel approach in the assessment of the internal consistency reliability of asymmetry scores. Previous studies estimated internal consistency reliability via Cronbach's alpha, using a relatively small set of asymmetry score that summarized activity over segments of the EEG data (e.g. one minute). Such an approach, however, will create estimates dependent on the number of segments utilized rather than the total amount of data recorded. Thus in the first study, individual FFT epochs were treated as items, thereby maximizing the total number of items used to estimate internal consistency reliability. Results of this study suggest internal consistency reliability is greater than previously reported, and as such, the duration of resting EEG data necessary to achieve a reasonable reliability criterion may be shorter than the current standard. In the second study, asymmetry scores were assessed as a specific case of difference scores, which are susceptible to a statistical artifact associated with differences in true-score variance for the component measures. Predicted asymmetry scores associated with the statistical artifact were obtained by estimating the true-score variance of right and left alpha power. The use of hierarchical linear regression showed some influence of the statistical artifact on the relationship between asymmetry scores and a measure of depressive severity, suggesting that some caution may be warranted in interpreting asymmetry results with relatively small effect sizes.

Abstract:
Frontal alpha asymmetry is often used as a metric to compare activation between homologous frontal brain sites. A positive asymmetry refers to greater activation in the left hemisphere than in the right hemisphere, while the opposite is true of negative asymmetries. Two expansive but largely separate bodies of research have examined the relationships between (1) frontal asymmetry scores and mood, and (2) mood and emotional memory performance. Specifically, one body of research has found that positive moods are associated with positive asymmetries while negative moods are associated with negative asymmetries. A second body of literature has examined the effects of mood on affective memory performance found that individuals tend to preferentially recall stimuli whose valence (positivity or negativity) is consistent with their current moods, often at the expense of stimuli whose valence is inconsistent with their current moods. Researchers in this area report that individuals in positive moods tend to recall more positive than negative words while those in negative moods recall more negative than positive words in memory tasks. This effect has been termed mood-congruent memory. As frontal asymmetry appears to underlie mood, and mood differentially affects performance on emotional memory tasks, it is surprising that no research has focused on a possible direct relationship between frontal asymmetry and emotional memory performance. The present study attempted to replicate previously described relationships between (1) frontal asymmetry and mood, and (2) mood and emotional memory performance. The main goal of the study, however, was to bridge the gap between frontal asymmetry and selective recall of emotional words by attempting to correlate frontal asymmetry indices with emotional memory performance. Results supported the expected mood-congruent memory effects and a significant relationship between asymmetry and mood in the expected direction. While a correlation between asymmetry and affective memory performance was not found, groups based on asymmetry scores found that the positive asymmetry group showed increased memory performance for positive words and total words, while the negative asymmetry group showed impaired memory for positive words and total words. Further examination of links between alpha asymmetry and affective memory could corroborate the present asymmetry group differences in memory. Future findings would provide the first neuropsychological underpinning of mood-congruent memory effects. Additionally, support for a relationship between asymmetry and affective memory could lead to the formation of a unifying theory of asymmetry and memory that draws on current models of brain activation, executive function, emotion, and memory.

Abstract:
Resting frontal alpha asymmetry was measured with an electroencephalogram in 28 volunteers to predict the evaluation of emotions in music. Sixteen music excerpts either expressing happiness, sadness, anger or fear were rated by the participants with regard to conveyed mood, pleasantness and arousal. In addition, various variables of music background were collected. The experiment started with the assessment of current mood, followed by the evaluation of the music excerpts, and finished with the assessment of the participants’ approach and withdrawal behaviour. The results showed that each music excerpt was specic for the intended mood except for music of the category anger which obtained also high ratings for fear. These music excerpts were also the only ones for which a difference in ratings between relatively more left-active and right-active participants could be observed. Partly against expectations, left-dominant volunteers perceived music excerpts of the category anger to express more fear and anger than right-active participants. Results are interpreted within the behavioural inhibitionand approach model of anterior brain asymmetry.

Frontal electroencephalographic (EEG) alpha (α) asymmetry may index the activation of lateralized affect and motivation systems in humans. Resting EEG activation was measured and its relationship to Iowa gambling task (IGT) performance was evaluated. No effects were found for α power asymmetry. However, beta (β) power asymmetry, an alternative measure of resting EEG activation, was associated with the number of risky decisions made in the early portion of the task. Additionally, IGT deck selection patterns suggest there are at least three distinct performance styles in healthy individuals. Interestingly, β power asymmetry contradicts performance predictions based on accepted frontal asymmetry affect and motivation models.

Abstract:
The immune system has been suggested as crucial in brain and psychological functioning. More precisely, immune markers reflecting immune system activity are important for psychological and mental health, as evident by their role in the physiopathology of depression and in the impairment of executive functions. Frontal alpha asymmetry (FAA), an electroencephalographic marker of brain function, has also been linked to such psychopathology and is thought to reflect psychological processes underlying approach- versus withdrawal-related motivation and higher-order inhibitory control. Only a few studies have linked FAA to immune markers but notably found a negative association between IL-6, a pleiotropic pro-inflammatory cytokine, and FAA. The aim of the present work is thus to study the relationship between various immune markers (including pro-inflammatory cytokines and IL-6) and FAA. 35 healthy young male participants underwent a resting EEG recording and blood sampling from which immune markers were measured. The results did not suggest an association between IL-6 and FAA. No other immune markers were either suggested to be associated to FAA. The complexity of the immune system (e.g., effect of cytokines) is underlined and may explain the results. Despite such results, the implication of true negative correlations between FAA and circulating immune markers, as suggested in previous studies, is discussed in the light of the theoretical models of FAA.

Abstract:
The relationship between frontal EEG asymmetry and emotional reactivity is well established in the literature and there is some evidence of a causal link between the two variables (e.g., Allen et al., 2001). EEG biofeedback has been shown to improve depressive symptoms in clinical populations (e.g., Baehr et al., 1997 and Earnest 1999), however concurrent participation in other forms of treatment limits their conclusions. The present study was a double-blind clinical trial of a noninvasive alternative treatment for depression using EEG biofeedback of frontal alpha asymmetry and, of the 19 right-handed participants who were randomly assigned to receive contingent or noncontingent biofeedback, only seven completed three sessions per week for 12 weeks. Since only one participant in the noncontingent group completed all 36 sessions, group comparisons were not conducted. Although self-reported depression as determined by HRSD and BDI scores improved over time, this was independent of biofeedback training, because EEG biofeedback did not produce significant changes in frontal alpha asymmetry. In addition, there were no significant within-subjects correlations between asymmetry and BDI score or target value and BDI score.

Abstract:
Premenstrual dysphoric disorder (PMDD) is a severe dysphoric form of premenstrual syndrome (PMS) that is included as a diagnosis for further study in the DSM-IV (APA, 2000). A primary aim of the present study was to characterize the co-occurrence of PMDD and major depression, in a sample that spans the entire range of depressive severity. The range included non-depressed controls, women meeting criteria for dysthymia, and women meeting criteria for current Major Depressive Disorder (MDD). Co-occurrence of MDD and PMDD were only statistically significant when considering Lifetime MDD. Resting frontal electroencephalographic (EEG) asymmetry has been hypothesized to tap a diathesis toward depression or other emotion-related psychopathology. Another primary aim was to assess Frontal EEG asymmetry in college women who meet criteria for Pre-Menstrual Dysphoric Disorder (n = 25) and 25 matched controls. Participants were assessed four times in a two week period. Women reporting low premenstrual dysphoric symptomatology exhibited greater relative left frontal activity at rest than did women high in premenstrual dysphoric symptomatology. These results are consistent with a diathesis-stress model for premenstrual dysphoric symptomatology. A secondary aim was to assess whether individuals with PMDD or menstrual related mood variability, but no current diagnosis of depression, have an increased family history of depression. Promising evidence of a relationship between family history of MDD and a likelihood of PMDD was discovered. A trend was found for Spectrum PMDD women: a higher rate of Family History of MDD (36%) than non PMDD women (19.6%). Ideally, resting frontal electroencephalographic (EEG) asymmetry could help us learn more about the etiology of depression and hormonal-related depression specifically, and test whether they may share etiological factors.

The purpose of the current study was to investigate the relationships among trait anxiety, competition trait anxiety, frontal EEG asymmetry, and alpha power in male table tennis players. Forty-seven preelite table tennis players completed STAI and SCAT, and resting EEG were recorded. Cleaned EEG were fast Fourier transformed intoαfrequency bands (8-13Hz). The frontal asymmetry calculated from R-L was also obtained. The results of this study were: 1. Trait anxiety and Competition trait anxiety were positively moderately correlated to each other. 2. Trait anxiety and Competition trait anxiety has no predictive power on frontal EEG asymmetry. 3. Competition trait anxiety could explain and predict approximately 10﹪variance of pretest alpha power at F3, F4, and F7.

Abstract:
Previous studies have shown that quantitative electroencephalography (qEEG) provides measures of brain wave voltage and symmetry within each of the standard bandwidths. These qEEG measures are neurophysiological correlates of brain wave signatures for various aspects of cognition and behavior and are susceptible to neurofeedback training for improving human performance. Using exam scores and an individualized self-inventory (ISI) of psychosocial interactions, we provide unique data for probing behavioral and cognitive performance of medical students. Increments in voltage within the standard theta (4–7 Hz) and beta (15–20 Hz) frequencies and decrements in the theta–beta ratio (TBR) suggest improvements in attentional control. Associations between right-sided frontal alpha asymmetry (fAA) and ISI scores for negative self-perceptions suggest a novel qEEG signature for emotional balance. These findings suggest that changes in qEEG voltages and asymmetries may be predictive of improvements in attentional control, cognitive performance, and psychosocial skills, as well as serving as surrogate markers for neurofeedback training-related changes in neuroplasticity.

Abstract:
ABSTRACT Massage refers to a wide range of techniques such as effleurage, petrissage, tapping, friction, and vibration, yielding pressure on soft tissues done manually or with devices. Nowadays, massage is widely used in everyday life, sport, and medical care as a complementary and alternative therapy. Although its millenniums of use, there is very little research on its effects on health and disease conditions. As one of the main reasons for this can be pointed out, research methods, most of which need special equipment, and different professionals, are subjective or invasive. Recently, some studies have assessed the physical and physiological effects of massage, such as electroencephalography (EEG). EEG is a rapidly non-invasive test that provides evidence of how the brain functions over time. EEG matured over the decades due to advances in technology. Now it has greater sensitivity, digital recording on hard drives, allowing different processing, and are developed consumer-grade devices, which provide easier obtaining of EEG signals outside of the traditional laboratory settings. Advanced dry wireless headsets enable the use of EEG diagnostic in a natural environment at home, working place, sports halls, fields, etc. EEG has been used for the evaluation of effectiveness and in the comparison between different massage processes. Research investigating the physiological effects of massage therapy with EEG has suggested that massage therapy reduces anxiety, increases frontal delta activity, decreases frontal alpha and beta activity, shifts frontal alpha asymmetry from right-hemisphere dominance to left-hemisphere dominance, increases resting-state alpha activity in the left anterior cingulate cortex, etc. Conclusion: Together, these findings provide evidence that massage therapy acts to modulate EEG activity and that EEG diagnostic can be a useful non-invasive, and accurate, objective research method for investigation and illustration of massage therapy effects.
