Brain Structural Networks Associated with Intelligence and Visuomotor Ability

Abstract Increasing evidence indicates that multiple structures in the brain are associated with intelligence and cognitive function at the network level. The association between the grey matter (GM) structural network and intelligence and cognition is not well understood. We applied a multivariate...

description	Abstract Increasing evidence indicates that multiple structures in the brain are associated with intelligence and cognitive function at the network level.
