Normal somatotopy in SI of a tyrosinase-negative albino cat.

Because of known abnormalities in both the visual and auditory pathways of tyrosinase-negative albino cats, we mapped the primary somatosensory cortex (SI) in one such cat electrophysiologically. We detected absolutely no sign of abnormality in terms of somatotopy, and conclude that if anomalies do exist in the albino somatosensory system, they are either very subtle or lie outside SI.
