“…Studies also showed that hand preference measurement using questionnaires could be impacted by multiple factors [ 42 , 43 ], namely genetic factors [ 44 , 45 ], demographic factors such as age [ 46 ] and gender [ 47 ], cultural environmental factors such as forced right-hand use for writing (e.g. France: [ 48 ]; Finland: [ 44 ]), and region/area of the country [ 49 ], as well as performance abilities (e.g. mathematical ability: [ 50 ]; hand performance: [ 51 ]) and physical impairments (e.g.…”

Despite significant scientific advances, the nature of the left-hemispheric systems involved in language (speech and gesture) and manual actions is still unclear. To date, investigations of human laterality focused mainly on non-communication functions. Although gestural laterality data have been published for infants and children, relatively little is known about laterality of human gestural communication. This study investigated human laterality in depth considering non-communication manipulation actions and various gesture types involving hands, feet, face and ears. We constructed an online laterality questionnaire including 60 items related to daily activities. We collected 317 594 item responses by 5904 randomly selected participants. The highest percentages of strong left-lateralized (6.76%) and strong right-lateralized participants (75.19%) were for manipulation actions. The highest percentages of mixed left-lateralized (12.30%) and ambidextrous (50.23%) participants were found for head-related gestures. The highest percentage of mixed right-lateralized participants (55.33%) was found for auditory gestures. Every behavioural category showed a significant population-level right-side bias. More precisely, participants were predominantly right-lateralized for non-communication manual actions, for visual iconic, visual symbolic, visual deictic (with and without speech), tactile and auditory manual gestures as well as for podial and head-related gestures. Our findings support previous studies reporting that humans have left-brain predominance for gestures and complex motor activities such as tool-use. Our study shows that the Rennes Laterality Questionnaire is a useful research instrument to assess and analyse human laterality for both manipulation and communication functions.

“…Right-handed patients with BPD (n = 20) and SCZ (n = 20) matched for age (18–54), gender and education were recruited from the outpatient setting of a large tertiary hospital. Handedness was assessed through the Edinburgh Handedness Inventory ( Espírito-Santo, 2017 ). All patients had an ICD-10 diagnosis of BPD or SCZ confirmed through direct interview by an experienced psychiatrist and medical records reviewing.…”

Highlights Dysfunction of social cognition (SC) has been described in severe mental disorders. First fMRI study comparing SC in schizophrenia (SCZ) and bipolar disorder (BPD). We found dissociated activation of SCZ and BPD in the right supramarginal gyrus. Contrasting activation was also found in the left posterior superior temporal gyrus. Temporoparietal junction activation patterns could be investigated as biomarkers.

Background: Social cognition impairment is a key phenomenon in serious mental disorders such as schizophrenia (SCZ) and bipolar disorder (BPD). Although genetic and neurobiological studies have suggested common neural correlates, here we hypothesized that a fundamental dissociation of social processing occurs at an early level in these conditions. Methods: Based on the hypothesis that key structures in the social brain, namely the temporoparietal junction, should present distinctive features in SCZ and BPD during low-level social judgment, we conducted a case-control study in SCZ (n=20) and BPD (n=20) patients and controls (n=20), using task-based fMRI during a Theory-of-Mind (ToM) visual paradigm leading to interpretation of social meaning based on simple geometric figures. Results: We found opposite neural responses in two core ToM regions: SCZ patients showed social content-related deactivation (relative to controls and BPD) of the right supramarginal gyrus, a region which activity is required to overcome egocentric overmentalizing, while the opposite pattern was found in BPD; reverse patterns, relative to controls and SCZ, were found in the left posterior superior temporal gyrus, a region involved in inferring others intentions. Receiver-operating-characteristic curve analysis showed 88% accuracy in discriminating the two clinical groups based on these neural responses. Conclusions: These contrasting activation patterns of the temporoparietal junction in SCZ and BPD represent mechanistic differences of social cognitive dysfunction that may be explored as biomarkers or therapeutic targets.
