of the temporal lobe correlated with scores of visuo-motor integration tests156. Another study found impairments in tasks related to interhemispheric information transfer in children with PEA, and showed that these impairments correlated with reductions in the size of CC157. These abnormalities in CC may correlate with certain functional impairments in executive functions, attention span, coordination, and verbal learning abilities often seen in individuals with PEA.
