title: [Motor neglect: issues and prospects].
abstract: Although the motor and sensory components of the neglect syndrome appear as dependent on a unitary attentional process, the clinical observation of pure motor neglect raises the possibility of segregation between attentional and intentional neural mechanisms. Neuroanatomical evidence suggests a separate role for the anterior and posterior cingulum. The anterior cingulum mainly projects to the supplementary motor area, the superior premotor area and the prefrontal granular cortex whereas the posterior cingulum mainly controls the inferior parietal lobule. The role of the intralaminar thalamic nuclei, together with the frontostriatal loops is considered. Behavioral neurology should strengthen its analytical approach in order to dissociate, by appropriate testing, the separate operations which contribute to relate perception and action. Several new hypotheses are presented.
