摘要: A small corpus callosum (CC) is one of the most replicated neurobiological findings in autism spectrum (AS). However, its effect on interhemispheric (IH) communication unknown. We combined structural (CC area and DWI), functional (task-related fMRI activation connectivity analyses) as well behavioral (Poffenberger Purdue tasks) measures to investigate IH integration adult AS individuals typical intelligence. Despite similar transfer time performances bimanual tasks, CC sub-regions connecting frontal parietal cortical areas were smaller than non-AS individuals, while those visual regions similar. The was lower during presentation stimuli. Behavioral related properties subregions motor but posterior individuals. Furthermore, there greater between group. Levels also stronger autistic subjects, opposite true for non-autistic Thus, plays an important role visuo-motor tasks These extend established enhanced perception cognition information transfer.
