[Properties and organization of pyramidal neurons of the rat motor cortex]
Abstract
Antidromic potential sin cortical neurons elicited by stimulation of pyramids and different segments of the spinal cord were studied with the aid of extracellular recording in rats. Axons of about 2/3 of the cells under study formed the cortico-spinal tract passing through the ventral portion of the dorsal column up to the lumbar segments of the spinal cord. Conduction velocity along the cortico-spinal axons varied from 2.3 to 17.0 m/sec.
