Abstract

A great number of labeled cells, with a topographic distribution in the nucleus, was observed following some HRP cortical injections, indicating that different parts of VA send consistent projections to definite cortical zones: the ventro-medial sector to the prefrontal cortex, the whole ventral sector to the motor cortex, the central part to the primary somatosensory area, and the dorsal one to the anterior suprasylvian cortex. Overlapping among the different sectors of the nucleus was evident, but no variations in the retrograde labeling was observed between rostral and caudal levels of VA. A new neurons were labeled in other cases, demonstrating that VA is also connected to widespread cortical areas (in particular, in this series of experiments, the ventral part of the secondary somato-sensory area, insular cortex, posterior suprasylvian and ectosylvian gyri, cingulate cortex). No labeled cells were detected in VA following other cortical HRP injections (primary visual area, dorsal part of the secondary somato-sensory area, temporal cortex).
