• The arrangement of eight groups of axons afferent to the nuclei of the dorsal division of the medial geniculate body is described in rapid Golgi impregnations from young cats.
• The anterior dorsal nucleus is as significant for the dorsal fields of the auditory cortex as the ventral nucleus of the medial geniculate body is for the temporal fields of the auditory cortex.
• The medial geniculate body is situated on the caudal aspect of the thalamus and is the last major relay station for ascending auditory fibers before they reach the cortex.
• The medial geniculate body is located dorsomedial to the lateral geniculate body.
• The results indicated that the medial geniculate body is part of a circuit necessary for the release of corticosterone specifically in response to loud noise but not to restraint or ether stress.
