[Functional organization of the kinesthetic projections of the 1st somatosensory region of the cat cortex].
Electrophysiological studies were performed on adult cats under ethaminal anesthesia. Kinesthetic potentials were evoked by passive extension of the ulnar joint and recorded in contralateral primary somatosensory cortical area. Natural (nonelectrical) stimulation of peripheral kinesthetic receptors was performed according to the author's original method. The results obtained show significantly shorter latent period of contralateral kinesthetic potentials in comparison with somatosensory potentials in response to electrical stimulation of the skin. These data demonstrate the possibility of super-rapid conduction of modal-specific volleys to the cortical projection centres in the kinesthetic system of cats.
