An Experimental Electron Microscopical Study of a Direct Retino-Pulvinar Pathway in the Tree Shrew

Exp Brain Res. 1981;43(3-4):447-50. doi: 10.1007/BF00238389.

Abstract

After unilateral enucleation in the tree shrew (Tupaia glis), axo-dendritic synapses degenerate within two secondary visual centers (intergeniculate and lateral pulvinar nuclei). Degenerated optic terminals were found in both pulvinar nuclei on the contralateral side much more often than on the ipsilateral one.
