PARIETAL CORTEX - FROM SIGHT TO ACTION

Recent findings have altered radically our thinking about the function al role of the parietal cortex. According to this view, the parietal l obe consists of a multiplicity of areas with specific connections to t he frontal lobe, These areas, together with the frontal areas to which they are connected, mediate distinct sensorimotor transformations rel ated to the control of hand, arm, eye or head movements. Space percept ion is not unitary, but derives from the joint activity of the fronto- parietal circuits that control actions requiring space computation.
