Description of part
...is a prominent member of the superficial amygdala and occupies its rostromedial aspect (Figs. 1B, C; 3C, D; 4C). It consists almost entirely of small and medium sized lightly stained cells of various shape. It also contains some large cells which are more abundant towards the rostrodorsal aspect of the nucleus. The Me begins just caudal and medial to the LOT, overlying for a short distance the BAOT, and extends caudally until the temporal horn of the lateral ventricle appears. At this level, it lies dorsomedial to the cephalic pole of the AHi and forms the medial aspect of the anterior wall of this portion of the hemispheric ventricle. Along its entire extent the Me lies in direct apposition tot the ventrolateral side of the optic tract. On cytoarchitectural grounds, the Me is subdivided into a principal part or body, a small dense celled anteroventral part (MEAV) and a posterodorsal part (MEPD) at the caudal end of the nucleus (Price, 1981). In Golgi stained material (Fig. 7B), the ME displays mostly small neurons (5 micrometers-`0 micrometers) with a more radiate and extended (isodendritic) configuration. The Me includes both the medial amygdaloid nucleus of Yu (1969) and his "medial area (CO 3)" of the cortical nucleus. The present delineation of the Me subnuclei corresponds quite closely with the ones proposed by Bayer (1980) and Turner and Zimmer (1984).
