[Relation between the septal nuclei and the amygdaloid complex of the brain of the cat].
By means of retrograde and anterograde transport of horseradish peroxidase method it has been demonstrated in two series of experiments with injecting the enzyme into separate septal nuclei and the amygdaloid complex in cats that most of amygdaloid nuclei (cortico-medial, central and baso-lateral) are reciprocally connected only with two nuclei in the septum: with the nucleus of the diagonal bundle of Broca and with the nucleus of the terminal strip bed. The projections studied are topically organized. The cortico-medial and basal nuclei of the amygdaloid complex are reciprocally connected with the ventral part of the diagonal bundle of Broca and with the terminal strip bed nucleus. The central nucleus of the amygdala has reciprocal projections only with the terminal strip bed nucleus, and with the ventral part of the diagonal bundle of Broca it has only a unilateral connection. On the contrary, the lateral nucleus of the amygdala is reciprocally connected with the ventral part of the diagonal bundle of Broca, and is only projected on the terminal strip bed nucleus without getting any projections from it.
