Central projection of proprioceptive information from the wrist joint via a forearm 'muscle' nerve in the cat.

1. Peripheral nerves arising in joint capsules are known to contain a 'contaminating' contribution from muscle afferent fibres. In the present report we provide the first electrophysiological evidence that some joint afferent fibres may take an 'ectopic' path to the central nervous system via a nearby muscle nerve. 2. Experiments were conducted in… CONTINUE READING
