The amygdaloid body is a telencephalic structure belonging to the limbic system. The amygdaloid body consists of the two main nuclear groups: corticomedial and basolateral. The former-phylogenetically older group is composed of the central, medial, and cortical nuclei, while the latter, phylogenetically younger one, of the lateral, basolateral and basomedial ones. The results presented in our paper indicate differences in the structure and topography of the specific amygdaloid nuclei. Their subdivisions in the rabbit are not as evident as in the rat. Apart from structural differences, the cellular composition of specific nuclei does not differ distinctly. It can suggest that their intrinsic and extrinsic connections might be similar and the role and function of them is maintained (with few exceptions) through the phylogeny.
