The neuronal organization of the inferior colliculus of the adult cat. I. The central nucleus

The intrinsic organization of the central nucleus of the inferior colliculus has been studied in the adult cat by means of the Golgi and Nauta techniques. On the basis of cytoarchitecture and fiber connections, the central nucleus can be divided into: (i) a smaller, dorsomedial division consisting mainly of large cells and receiving fibers from the auditory cortex, lateral lemniscus and probably the central nucleus of the other side; (ii) a larger, ventrolateral division consisting mainly of medium and small cells but with some intermingled larger types. This part receives fibers from the lateral lemniscus only.
