Description of part
...is a relatively homogeneous mass of palley staining small and medium sized neurons (Atlas [Paxinos, 1982], Fig. 20). It extends from a level just caudal to the cephalic pole of the anterior basolateral nucleus until nearly the caudal end of the amygdaloid complex, occupying the dorsal aspect of the basolateral nucleus complex and enlarging as it progresses caudally (Figs. 1C, 2, 3C, D, E, 4A). On the basis of cell morphology and topography, the La can be divided into dorsolateral (LaDL), ventromedial (LAVM), and ventrolateral (LaVL) parts. The Golgi morphology of nerurons in the La, like those in the remaining divisions of the basolateral complex can be grouped in two primary types: pyramidal and non-pyramidal. The pyramidal neurons, which are undoubtely the predominant cell type in the whole basolateral nuclear complex, have a configuration closely resembling that of an isocortical pyramidal cell. The above description of the La corresponds closely to that by Krettek and Price (1978b). The present description differs markedly from the accounts by Gurdjian (1928) and Brodal (1947).
