title: Cells of origin of cortical projections to dorsal column nuclei, spinal cord and bulbar medial reticular formation in the rhesus monkey.
abstract: Cells of origin of cortical fibers to the dorsal column nuclei, spinal cord and bulbar medial reticular formation were identified in 8 rhesus monkeys by means of the horseradish peroxidase (HRP) retrograde transport technique. After dorsal column nuclei injections small pyramidal neurons were labeled in the contralateral hemisphere in layer V of areas 3, 1, 2 and 5 and in layer V of the posterior part of area 4. In contrast, after spinal cord injections many area 4 giant Betz cells in the contralateral hemisphere were labeled as well as many other layer V pyramidal neurons in areas 4 and posterior 6 and in areas 3, 1, 2 and 5. Injections in the bulbar medial reticular formation labeled mainly medium sized layer V pyramidal neurons in area 6 and the anterior part of area 4 of both hemipsheres.
