Connections of the posterior thalamus with the amygdaloid body of the rat.

The thalamo-amygdaloid connections arising in the posterior thalamus were studied in the brains of rats by the Nauta-Gygax and Fink-Heimer methods. They begin mainly in the neurons of the supero-medial area of the posterior segment of the pulvinar and in the peripeduncular nucleus. The amygdalopetal fibers of this pathway pass through the zona incerta, cerebral peduncle, and the lateral hypothalamus. They end in the lateral nucleus and in the lateral part of the central nucleus of the amygdaloid body.
