Some Facets of the Organization of the Principal Division of the Cat Medial Geniculate Body
It is our purpose in this paper to review knowledge accumulated about the medial geniculate body — the auditory nucleus of the thalamus — by presenting new findings pertinent to older questions. Two major divisions of the cat medial geniculate body (MGB) have long been recognized: a region of medium-sized, closely-packed cells forming the dorsal and lateral sector of this part of the thalamus, and a medial division populated by larger, more loosely-packed neurons. These divisions are usually referred to as the principal division (Mgp) and magnocellular (Mgm) divisions, respectively (Rose and Woolsey, 1949, 1958).
