Abstract:
It has been suggested that one of the underlying causes of asymmetrical performance and left/right bias in sound riding horses is laterality originating in the cerebral cortices described in many species. The aim of this paper is to review the published evidence for inherent biomechanical laterality in horses deemed to be clinically sound and relate these findings to descriptions of sidedness in equestrian texts. There are no established criteria to determine if a horse is left or right dominant but the preferred limb has been defined as the forelimb that is more frequently protracted during stance and when grazing. Findings on left-right differences in forelimb hoof shape and front hoof angles have been linked to asymmetric forelimb ground reaction forces. Asymmetries interpreted as motor laterality have been found among foals and unhandled youngsters, and the consistency or extent of asymmetries seems to increase with age. Expressions of laterality also vary with breed, sex, training and handling, stress, and body shape but there are no studies of the possible link between laterality and lameness. In a recent study of a group of seven dressage horses, a movement pattern in many ways similar to descriptions of sidedness in the equestrian literature, e.g. one hind limb being more protracted and placed more laterally than the other, has been documented. The role of innate laterality versus painful conditions, training, human handedness and simply habit remains to be determined. Understanding the biomechanical manifestations of laterality in healthy horses, including individual variation, would yield a potential basis for how laterality should be taken into account in relation to training/riding and rehabilitation of lameness.

Abstract:
Tato přehledová studie se zaměřuje na fenomén laterality obecně i na její konkrétní formy, což jsou leváctví a asymetrie mozkových hemisfér. Autorka se snaží se tyto pojmy definovat, popsat a vysvětlit případný vztah mezi vedoucí rukou a asymetrií hemisfér, konkrétně specializovaných funkčních oblastí v mozku člověka. Ve studii jsou nastíněny teorie, které řeší otázku, proč lateralita rukou a mozku evolučně vznikla a z jakých důvodů se vyvine u jedince, a to z hlediska genetických příčin i možného vlivů prostředí. Studie následně popisuje leváctví a praváctví v lidské populaci, klasifikaci laterality rukou u člověka a možnosti, jak vedoucí ruku určit.

Abstract:
Abstract Purpose fMRI is increasingly used for presurgical language mapping, but lack of standard methodology has made it difficult to combine/compare data across institutions or determine the relative efficacy of different approaches. Here, we describe a quantitative analytic framework for determining language laterality in clinical fMRI that addresses these concerns. Methods We retrospectively analyzed fMRI data from 59 patients who underwent presurgical language mapping at our institution with identical imaging and behavioral protocols. First, we compared the efficacy of different regional masks in capturing language activations. Then, we systematically explored how laterality indices (LIs) computed from these masks vary as a function of task and activation threshold. Finally, we determined the percentile threshold that maximized the correlation between the results of our LI approach and the laterality assessments from the original clinical radiology reports. Results First, we found that a regional mask derived from a meta-analysis of the fMRI literature better captured language task activations than masks based on anatomically defined language areas. Then, we showed that an LI approach based on this functional mask and percentile thresholding of subject activation can quantify the relative ability of different language tasks to lateralize language function at the population level. Finally, we determined that the 92nd percentile of subject-level activation provides the optimal LI threshold with which to reproduce the original clinical reports. Conclusion A quantitative framework for determining language laterality that uses a functionally-derived language mask and percentile thresholding of subject activation can combine/compare results across tasks and patients and reproduce clinical assessments of language laterality.

Abstract:
Two hundred patients (100 male, 100 female) were tested by stimulation bilaterally at the Liver 3 acupuncture points (Taichong) to find if there was a relationship between right or left handedness and the side of greater sensation during stimulation. No relationship was found, but overall there was a greater sensitivity on the left in 69.5% of subjects. Twenty patients (10 male and 10 female) were selected and tested both at Liver 3 and with electro-acupuncture to both ears. A clear relationship was found between the side of greater sensitivity at Liver 3 and the more sensitive ear to electro-stimulation. It is suggested that bilateral testing of Liver 3 could be a useful guide to the selection of the side for treatment in auriculo-therapy.

Abstract:
Laterality has been found in a variety of reptiles. In turtles, one important behaviour is the righting response. Here, we studied laterality of righting response of two species of freshwater turtles, the Painted Turtle (Chrysemys picta) and the Eastern Musk Turtle (Sternotherus odoratus). We found evidence of individual-level laterality in righting response inC. picta, but notS. odoratus. Neither species showed evidence of population-level laterality in righting response. Our results suggest that there is variation in the extent of laterality of righting response in turtles. Possible explanations for variation in laterality of righting response in turtles include shell shape and use of terrestrial habitats. However, more species of turtles need to be examined to demonstrate any general patterns in laterality of righting response in turtles.

Abstract:
Purpose The aim of this study was to identify factors influencing pharyngeal laterality of bolus clearance through the pharyngoesophageal segment. Method Two swallowing trials (5-ml nectar-thickened liquid and 5-ml pudding) administered in the anteroposterior viewing plane during videofluoroscopy were extracted from a normative database of 195 healthy adult participants. Each swallow was determined as either having no laterality, right dominance/right side only, or left dominance/left side only. Descriptive measures were performed on all data variables. Chi-square tests were performed to determine the relationship between laterality and several factors, including age category, sex, race, and swallow task. Results The majority of swallows demonstrated no laterality. No significant associations were observed between laterality and the following factors: age category, race, or swallow task. Significant differences in laterality were observed between males and females, with females more likely to demonstrate no laterality. Conclusions Majority of swallows in the current healthy sample demonstrated no laterality preference. If present, males were more likely to demonstrate laterality compared to females. Laterality observed during videofluoroscopy does not imply impairment if there are no other factors present influencing bolus flow into the esophagus (e.g., mass). Study findings further define typical swallowing behaviors, allowing clinicians to better delineate normal variations from true impairment. Further research should include a larger sample of individuals aged 80 years and older, as well as additional swallowing tasks, to further investigate patient- and bolus-related factors on laterality.

Abstract:
Clear hand laterality patterns in humans are widely accepted. However, humans only elicit a significant hand laterality pattern when performing complementary role differentiation (CRD) tasks. Meanwhile, hand laterality in chimpanzees is weaker and controversial. Here we have reevaluated our results on hand laterality in chimpanzees housed in naturalistic environments at Fundació Mona (Spain) and Chimfunshi Wild Orphanage (Zambia). Our results show that the difference between hand laterality in humans and chimpanzees is not as great as once thought. Furthermore, we found a link between hand laterality and task complexity and also an even more interesting connection: CRD tasks elicited not only the hand laterality but also the use of tools. This paper aims to turn attention to the importance of this threefold connection in human evolution: the link between CRD tasks, hand laterality, and tool use, which has important evolutionary implications that may explain the development of complex behaviour in early hominins.

Abstract:
179 8- to 12-yr.-old children received hand-preference, eye-preference, dichotic (digits and nonverbal sounds) tests, and the Wide Range Achievement Test. These data and those from previous studies suggest that brain organization for receptive language laterality can be predicted by familial handedness in conjunction with assessed hand-eye preference. A model of optimum functional ear laterality patterns within a given brain organization is advanced. For example, the “typical” pattern of a right-ear (left-hemisphere) advantage for verbal stimuli was associated with high achievement scores only for right-handed individuals with a family history of dextrality.

Abstract:
An ocean of studies have pointed to abnormal brain laterality changes in patients with bipolar disorder (BD). Determining the altered brain lateralization will help us to explore the pathogenesis of BD. Our study will fill the gap in the study of the dynamic changes of brain laterality in BD patients and thus provide new insights into BD research. In this work, we used fMRI data from 48 BD patients and 48 normal controls (NC). We constructed the dynamic laterality time series by extracting the dynamic laterality index (DLI) at each sliding window. We then used k-means clustering to partition the laterality states and the Arenas–Fernandez–Gomez (AFG) community detection algorithm to determine the number of states. We characterized subjects’ laterality characteristics using the mean laterality index (MLI) and laterality fluctuation (LF). Compared with NC, in all windows and state 1, BD patients showed higher MLI in the attention network (AN) of the right hemisphere, and AN in the left hemisphere showed more frequent laterality fluctuations. AN in the left hemisphere of BD patients showed higher MLI in all windows and state 3 compared to NC. In addition, in the AN of the right hemisphere in state 1, higher MLI in BD patients was significantly associated with patient symptoms. Our study provides new insights into the understanding of BD neuropathology in terms of brain dynamic laterality.

Abstract:
All internal organs are asymmetric along the left–right axis. Here we report a genetic screen to discover mutations which perturb organ laterality. Our particular focus is upon whether, and how, organs are linked to each other as they achieve their laterally asymmetric positions. We generated mutations by ENU mutagenesis and examined F3 progeny using a cocktail of probes that reveal early primordia of heart, gut, liver and pancreas. From the 750 genomes examined, we isolated seven recessive mutations which affect the earliest left–right positioning of one or all of the organs. None of these mutations caused discernable defects elsewhere in the embryo at the stages examined. This is in contrast to those mutations we reported previously (Chenet al., 1997) which, along with left–right abnormalities, cause marked perturbation in gastrulation, body form or midline structures. We find that the mutations can be classified on the basis of whether they perturb relationships among organ laterality. In Class 1 mutations, none of the organs manifest any left–right asymmetry. The heart does not jog to the left and normally leftpredominantBMP4in the early heart tube remains symmetric. The gut tends to remain midline. There frequently is a remarkable bilateral duplication of liver and pancreas. Embryos with Class 2 mutations have organotypic asymmetry but, in any given embryo, organ positions can be normal, reversed or randomized. Class 3 reveals a hitherto unsuspected gene that selectively affects laterality of heart. We find that visceral organ positions are predicted by the direction of the preceding cardiac jog. We interpret this as suggesting that normally there is linkage between cardiac and visceral organ laterality. Class 1 mutations, we suggest, effectively remove the global laterality signals, with the consequence that organ positions are effectively symmetrical. Embryos with Class 2 mutations do manifest linkage among organs, but it may be reversed, suggesting that the global signals may be present but incorrectly orientated in some of the embryos. That laterality decisions of organs may be independently perturbed, as in the Class 3 mutation, indicates that there are distinctive pathways for reception and organotypic interpretation of the global signals.

AbstractAim: The aim of this study was to identify and analyze the types of laterality and level of general intelligence in primary school children, aged six to eight years.Methods: The sample consisted of 120 students, both boys and girls. General intelligence was measured using Raven’s Coloured Progressive Matrices (CPM), while laterality was assessed using the Harris Test for lateral dominance.Results: The results obtained highlight that the dominant type of laterality is RRR - completely right-handed with stably accomplished laterality (81 subjects), followed by RLR - crossed ocular-manual and stably accomplished laterality (29 subjects). The proportion of those with LLL laterality - completely left-handed with stably accomplished laterality is small (4 subjects). In terms of general intelligence, most participants had IQs that can be classified in the category of those with a higher level of intelligence (65 subjects), succeeded by those with a superior medium level (27 subjects).Conclusion: Identifying the type of laterality and level of intelligence of children participating in physical education and sports classes is needed in order to leverage the intervention on the psychomotor components and to facilitate the process of adaptation of the child to the school environment.

Abstract:
Hemispheric lateralization constitutes a core architectural principle of human brain organization underlying cognition, often argued to represent a stable, trait-like feature. However, emerging evidence underlines the inherently dynamic nature of brain networks, in which time-resolved alterations in functional lateralization remain uncharted. Integrating dynamic network approaches with the concept of hemispheric laterality, we map the spatiotemporal architecture of whole-brain lateralization in a large sample of high-quality resting-state fMRI data (N = 991, Human Connectome Project). We reveal distinct laterality dynamics across lower-order sensorimotor systems and higher-order associative networks. Specifically, we expose 2 aspects of the laterality dynamics: laterality fluctuations (LF), defined as the standard deviation of laterality time series, and laterality reversal (LR), referring to the number of zero crossings in laterality time series. These 2 measures are associated with moderate and extreme changes in laterality over time, respectively. While LF depict positive association with language function and cognitive flexibility, LR shows a negative association with the same cognitive abilities. These opposing interactions indicate a dynamic balance between intra and interhemispheric communication, i.e., segregation and integration of information across hemispheres. Furthermore, in their time-resolved laterality index, the default mode and language networks correlate negatively with visual/sensorimotor and attention networks, which are linked to better cognitive abilities. Finally, the laterality dynamics are associated with functional connectivity changes of higher-order brain networks and correlate with regional metabolism and structural connectivity. Our results provide insights into the adaptive nature of the lateralized brain and new perspectives for future studies of human cognition, genetics, and brain disorders.

Abstract:
Background/Aim. Speech disfluency (stuttering) is a multifactor disorder and its aetiology is a big unknown for the experts from various fields. Hemisphere dominance as the highest level in the process of integration of cortical functions is of special significance for the entire development. Praxis and gnosis related cortical organizers are the first to form; they become differentiated and functionally full in early childhood while the process of condensing is completed somewhere around the age of 7. Cortical activity organizers are definitely set at that age and from then on act from one hemisphere which becomes dominant for that function. Laterality is determined by hemisphere dominance, but it occurs as a special phenomenon and it is of great significance for personality. The aim of this research was to examine the influence and the relationship between hemisphere asymmetry on the occurrence of speech disfluency in children. Methods. Sixty children aged 5 to 7 years participated in this research. Thirty children suffer from speech fluency disorder (person who stutters ? PWS) and they belong to the experimental group while thirty children are fluent speakers (person who does not stutter ? PWNS) and they were the control group. Individual testing was used as a test method. Laterality assessment test was used as an instrument which consists of 5 sub-tests as follows: the assessment of hand-use laterality, the assessment of gestural handuse laterality, the assessment of foot laterality, the assessment of auditory laterality and the assessment of visual laterality. Results. Gestural hand-use laterality and auditory laterality in the PWS examinees were considerably worse in comparison to the PWNS examinees (?2 = 11.80, p = 0.002, and ?2 = 10.90, p = 0.003, respectively). Male examinees had worse scores in comparison with female examinees. Conclusion. There are certain changes in establishing a dominant hemisphere and differentiation of laterality in children who stutter in comparison with the children who are fluent speakers, which has been shown by statistically significant difference in accomplishments at the test of gestural hand-use laterality and the test of auditory laterality.

Abstract:
For centuries, a goal of training in many equestrian disciplines has been to straighten the horse, which is considered a key element in achieving its responsiveness and suppleness. However, laterality is a naturally occurring phenomenon in horses and encompasses body asymmetry, motor laterality and sensory laterality. Furthermore, forcibly counterbalancing motor laterality has been considered a cause of psychological imbalance in humans. Perhaps asymmetry and laterality should rather be accepted, with a focus on training psychological and physical balance, coordination and equal strength on both sides instead of enforcing “straightness”. To explore this, we conducted a review of the literature on the function and causes of motor and sensory laterality in horses, especially in horses when trained on the ground or under a rider. The literature reveals that body asymmetry is innate but does not prevent the horse from performing at a high level under a rider. Motor laterality is equally distributed in feral horses, while in domestic horses, age, breed, training and carrying a rider may cause left leg preferences. Most horses initially observe novel persons and potentially threatening objects or situations with their left sensory organs. Pronounced preferences for the use of left sensory organs or limbs indicate that the horse is experiencing increased emotionality or stress, and long-term insufficiencies in welfare, housing or training may result in left shifts in motor and sensory laterality and pessimistic mentalities. Therefore, increasing laterality can be regarded as an indicator for insufficiencies in housing, handling and training. We propose that laterality be recognized as a welfare indicator and that straightening the horse should be achieved by conducting training focused on balance, coordination and equal strength on both sides.

Abstract:
In functional laterality research, most ungulate livestock species have until recently been mainly overlooked. However, there are many scientific and practical benefits of studying laterality in ungulate livestock. As social, precocial and domestic species, they may offer insight into the mechanisms involved in the ontogeny and phylogeny of functional laterality and help to better understand the role of laterality in animal welfare. Until now, most studies on ungulate livestock have focused on motor laterality, but interest in other lateralized functions, e.g., cognition and emotions, is growing. Increasingly more studies are also focused on associations with age, sex, personality, health, stress, production and performance. Although the full potential of research on laterality in ungulate livestock is not yet exploited, findings have already shed new light on central issues in cognitive and emotional processing and laid the basis for potentially useful applications in future practice, e.g., stress reduction during human-animal interactions and improved assessments of health, production and welfare. Future research would benefit from further integration of basic laterality methodology (e.g., testing for individual preferences) and applied ethological approaches (e.g., established emotionality tests), which would not only improve our understanding of functional laterality but also benefit the assessment of animal welfare.

Abstract:
Abstract Worldwide trainers ask if there is a rotation scheme, which facilitate the learning of the elements with longitudinal rotations. Although there are some research on it, they did not attempt to verify a total scheme, but merely to see the relationship between two elements or four elements. In this study we analyse the appreciation of experts N = 161 coaches (age: 34.9 ± 10.9) from different levels of expertise and from different countries (ARG, BOL, BRA, CHI, ECU, ELS, GER, GUA, HON, MEX, PAN, PER, URU, VEN) with 12 ± 8.8 years of experience regardinghow gymnasts should execute 27 different elements in 5 male apparatus. We chose these elements, because we wanted to have movements with rotation in upright stance, upside down and in combination with transversal rotation. Through a questionnaire for coaches, we tried to verify if there are differences, coincidences or even immovable rules in the rotation scheme that gymnasts use (or should use). The answers were typologized with three categories of rotational preference: unilateral consistent twister, bilateral consistent twister and inconsistent twister. The study aimed to answer several questions: Do coaches agree on how the rotation scheme should be in gymnastics? How do coaches (former gymnasts) determined which way to turn? Do the handedness or the footedness influence on the direction of rotation? Does the personal rotation scheme influence on the concept of appropriate rotation scheme? Do the national practices influence the rotation scheme? Are there differences in appreciation between coaches at different levels? Are unambiguous rules among the elements?
