Abstract

The morphology and localization of neurons of the thalamic ventrobasal complex projecting to the primary somatosensory cortex were studied in cats by the retrograde axonal transport of exogenous horseradish peroxidase method. Different types of neurons were detected: triangular, round with symmetrical processes, oval with processes diverging asymmetrically, and fusiform. Tagged neurons were distributed as two large populations in the central region of the complex adjoining the boundaries of the two nuclei. Comparison with the somatotopic map showed that the tagged neurons were concentrated mainly in the projection area of the forelimb and head. Since microinjections of peroxidase into the somatosensory cortex also were given in the projection areas for the forelimb and head, the results confirm the neurophysiological concept of strict somatotopic organization of thalamocortical input.
