Cerebral Functional Asymmetry and MBD Children: A Synergistic Deficit of Hemispheres?

Abstract

The functional cerebral organization of minimal brain-damaged (MBD) children was studied by testing tactile-visual matching of concrete objects. The results revealed that left hand performance was significantly better than the right in the MBD children while normal controls showed no hand difference, and overall performance level was poor for MBD children. These findings are consistent with the view that tactile matching of concrete objects requires hemispheric synergy and that MBD children lack this synergy.
