Ulnar nerve innervation of paw and SI cortex of cat: substrate for reorganization

We studied the distribution of the peripheral nerves innervating the distal forepaw by recording receptive fields from fascicles of the ulnar, radial, and median nerves and compared this result with the peripheral nerve representation in primary somatosensory (SI) cortex of cat. Our findings suggest...

Summary:We studied the distribution of the peripheral nerves innervating the distal forepaw by recording receptive fields from fascicles of the ulnar, radial, and median nerves and compared this result with the peripheral nerve representation in primary somatosensory (SI) cortex of cat. Our findings suggest that SI cortex receives input, in large part, from multiple peripheral nerves even when those nerves do not show a strong overlapping pattern in the periphery. This overlap pattern observed in SI cortex may be responsible, in part, for the immediate reorganization which is known to follow peripheral nerve deafferentation.
