title: The intraspinal branching patterns of fast and slow pyramidal tract neurons in the cat.
abstract: Antidromic activation of single pyramidal tract neurons (PTNS) was obtained in cats by stimulating either the dorso-lateral funiculus with ball-electrodes, or the spinal gray matter with microelectrodes. The results indicate that the distribution area of single PTNS is much wider than the area of a single motor nucleus, suggesting that single PTNS may influence different motor nuclei.
