Observations on Tonotopic Organization within the Rat Inferior Colliculus Using 2‐Deoxy‐D[1‐ 3 H] Glucose

Abstract
Tonotopic organization is a major feature of central auditory structures. The tritiated 2-deoxyglucose metabolic marking technique is demonstrated to be useful for visualizing isofrequency contours in the rat inferior colliculus. Following pure-tone stimulation, the central nucleus of the inferior colliculus shows discrete, prominent banding patterns and a well-organized tonotopic arrangement.
