Individual variation in brain network topology is linked to emotional intelligence

Abstract

Background-Social cognitive ability is a significant determinant of functional outcome, and deficits in social cognition are a disabling symptom of psychotic disorders. The neurobiological underpinnings of social cognition are not well understood, hampering our ability to ameliorate these deficits.Objective-Using 'resting state' functional magnetic resonance imaging (rsfMRI) and a transdiagnostic, data-driven analytic strategy, we sought to identify the brain network basis of emotional intelligence, a key domain of social cognition.Methods-The study included 60 participants with a diagnosis of schizophrenia or schizoaffective disorder and 45 healthy controls. All participants underwent a rsfMRI scan. Emotional Intelligence was measured using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). A connectome-wide analysis examined how each individual brain voxel's connectivity correlated with emotional intelligence using multivariate distance matrix regression (MDMR).Results-We identified a region in the left superior parietal lobule (SPL) where individual network topology is linked to emotional intelligence. Specifically, in high scoring individuals, this region is a node of the Default Mode Network and in low scoring individuals, it is a node of the Dorsal Attention Network. This relationship was observed in both schizophrenia and healthy comparison participants.

Individual Variation in Brain Network Topography is Linked to Schizophrenia Symptomatology

“…It is notable that in both this manuscript and our previous report on social cognition 11 , we demonstrated that the most significant connectivity-phenotype relationships in the entire brain were driven by variation in network topology. The increasing prevalence of fully data-driven connectivity studies will determine is this (i.e.…”

“…The implication of this result is that recently observed links between variation in network topology and normative cognitive / behavioral phenotypes also apply to disease-specific symptoms [9][10][11] . More broadly, this result lends support to the hypothesis proposed by by Bijsterbosch et al that previously reported cross-subject variations in functional connectivity are in fact mis-interpretations of variation in the spatial organization of brain networks 9 .…”

“…Individual variation in network topology among healthy control participants has been demonstrated previously [3][4][5][6][7][8] . Until very recently, the relevance of individual network topology to cognitive / behavioral variation has been undetermined but recent reports have linked individual topology to several cognitive and behavioral phenotypes [9][10][11] . To date these reports have examined these phenotypes in healthy populations 9,10 or have examined normative processes (e.g.…”

“…To date these reports have examined these phenotypes in healthy populations 9,10 or have examined normative processes (e.g. social cognition) in clinical populations 11 . Left unaddressed is the question: Is individual network topology linked to clearly pathological (i.e.…”

Evaluation of the Mental Ability of the Student Athletes and Examining their Emotional Intelligence Levels

“…Researches try to describe the relationship of the brain and emotional cognitive features with the experience (Ling et al, 2019;Brizendine, 2006). It encounters us as an important finding that (Ling et al, 2019) whether the emotional and cognitive structures of the brain establish a bond or not, and they found that the related parts of the brain were managed together according to his research.…”
