The basal amygdaloid nucleus was studied in 17 male rabbits weighing 1.5-2kgs, by Golgi staining method. The neurons were studied under light microscope and divided into (i) large neurons and (ii) small neurons, depending upon their dendritic trees and body size. Neurons with thick apical dendrites similar to the cortical pyramidal cells were grouped as pyramidal neurons. The neurons of the basal nucleus were further classified into (a) dorsal and (b) ventral, according to their position in the amygdala. Neurons were analysed by the original method of Leontovich (1969). Body size, number of dendrites, number of spines and length of dendrites were measured. Derivative field and relative length of dendrites were determined.
