Description of part
...is formed by two ovoid cell masses succeeding one another in the rostrocaudal direction (Figs 1C; 3C, D, E; 4B, C). In AChE preparations, the BM shows, in general, a very poor staining reaction which contrasts markedly eith the very strong one in the BL (Fig. 4C). In Golgi preparations (Fig. 7D), the BM shows very similar neuronal types to those in the La and BL. However, the pyramidal cells in the BM are the smallest in the basolateral complex (in soma size, thickness of dendrites and number of dendritic branch points). Modified pyramids are more frequently found in BM than in the other members of the complex. The BM of the present account corresponds to: (i) the amygdala propria medialis of Uchida (1950 and his amaygdala superficialis oralis intermedia; (ii) the smaller celled part of the accessory basal nucleus of Yu (1969) and his small celled part of the basal nucleus; (iii) in part to the basomedial amugdaloid nucleus of Krettek and Prices (1978b); (iv) Turner and Zimmer's (1984) basal nucleus of the amygdala, posteromedial part and their basal accessory nucleus of the amygdala; and (v) the posterior and anterior parts of Bayer's (1980) basomedial nucleus.
