[Retino-pulvinar pathway of the cat brain]

Abstract

Peculiarities on axonal distribution and termination of the retinal ganglionar cells within the limits of the thalamic pulvinar nuclei have been studied in 10 cats by means of the radioautography method combined with silver nitrate impregnation (Fink--Heimer technique). The ganglionar cells have projections on two pulvinar nuclei -- the lateral and the inferior. The medial pulvinar nucleus has no similar connections. The retinal projections in the pulvinar nuclear complex are bilateral and nearly symmetrical, the contralateral projections of the pathway somewhat predominate.
