The dynamics of interhemispheric collaboration and hemispheric control.
This article reviews recent models of how the two hemispheres collaborate to facilitate efficient information processing. The strengths and weaknesses of behavioral techniques and structural and functional neuroimaging techniques are considered as they apply to these problems. The role of the corpus callosum as an equilibrator of activation between the two hemispheres is discussed and linked with its role as a dynamic modulator for the mobilization of hemispheric resources. Issues related to metacontrol and dynamic fluctuations in hemispheric control are also considered.
