Abstract

Implantation of an HRP-pellet into motor nuclei at the T1 segment resulted in retrograde labelling of laminae V-VII neurones densely at C6-C8 in cats. Electrophysiological experiments showed the presence of neurones in this region that received inputs from skin afferents and cortico- and rubrospinal tracts, sent axons descending in the lateral funiculus, and distributed in the motor nucleus at T1. Termination in T1 motor nuclei was also verified by intra-axonal staining with HRP. The input and output properties of these neurones indicated that they can be premotor neurones of skin reflex pathways to T1 motoneurones.
