Abstract

Retinal projections to the lateroposterior and pulvinar nuclear complex (LP-Pul) in the cat were studied using anterograde horseradish peroxidase (HRP) tracing. After injecting HRP into the vitreous cavity of one eye, HRP-labeled presumed axon terminals were found in the LP-Pul bilaterally, with a contralateral predominance. The areas of distribution of these terminals were seen as a thin sheet at the lateral extreme of the LP-Pul, and as a few small spots within the LP-Pul, especially in the regions along the dorsomedial border of the caudal part of the LP-Pul.
