title: Ipsilateral retinal projections and laminations of the dorsal lateral geniculate nucleus in the eastern chipmunk (Tamias sibiricus asiaticus).
abstract: The ipsilateral retinal projections and laminations of the dorsal geniculate nucleus (LGNd) were studied in the eastern chipmunk (Tamias sibiricus asiaticus). From cyto-, myelo- and chemoarchitectures the LGNd was divided into the ventromedial and dorsolateral parts. Anterograde axonal transport of wheat germ agglutinated horseradish peroxidase (WGA-HRP) and Fink-Heimer staining after unilateral eye removal both indicated that the ipsilateral projection terminates in lamina 2 of the ventromedial part and in lamina 3b of the dorsalateral part. The remaining laminas, lamina 1 of the ventromedial part and laminas 3a and 3c of the dorsolateral part, receive afferents from the contralateral retina. It was suggested that laminas 1 and 2 of the chipmunk's LGNd correspond to laminas A and A1 of the cat's LGNd, and the lamina 3 complex to its lamina C complex.
