Tecto-thalamo-striatal visual pathway in the primate

Abstract

Event Abstract Back to Event Tecto-thalamo-striatal visual pathway in the primate Anett Nagy1*, Károly Gulya1, György Benedek1 and Attila Nagy1 1 University of Szeged, Department of Physiology, Hungary In our experiments, we studied the possibility that new visual connections exist in the Macaca mulatta brain between 1) the thalamus and the superior colliculus (SC), and 2) the thalamus and the caudate nucleus (CN). We applied choleratoxin as a retrograde tracer (injected to the CN), and fluoro-dextrane-amine (FDA) as a both retrograde and anterograde tracer (injected to the SC). Our purpose was to prove a direct neuronal connection originating from the SC to the thalamus. The monkey brains were processed for histology and immunohistochemistry. Both FDA-labeled axons and choleratoxin-marked neurons were seen in the ventrolateral posterior nucleus of the thalamus (VLp) and in the CN. Furthermore, the anterogradely labeled axons and retrogradely labeled cell bodies overlapped in the VLp. Our histological and immunohistochemical data support the notion that a direct tecto-thalamic connection exists between the SC and the VLp of the thalamus, and suggest the existence of a direct tecto-striatal and an indirect tecto-thalamo-striatal pathway in the mammalian brain. The study was supported by OTKA/NKTH Hungary grant 68594 and OTKA/Hungary grant PD 75156. Conference: IBRO International Workshop 2010, Pécs, Hungary, 21 Jan - 23 Jan, 2010.
