[Projections of the amygdala and septum to the caudate nucleus of the cat brain].

By means of the retrograde axonal transport of horseradish peroxidase in the cat, direct projections of neurons in the magno- and mediocellular parts of the basal nucleus of the amygdalar complex have been stated nearly to all parts of the caudate nucleus and projections of a small amount of neurons in the nucleus of the Brocka diagonal ligament--only to the medial edge of the caudate nucleus. The possibility to divide the caudate nucleus into limbic and non-limbic parts is discussed.
