Retinotopic organizations of the expanded ipsilateral projection to the rat's superior colliculus; variations along its rostrocaudal axis.
The retinotopic organization of the expanded projection to the ipsilateral colliculus was studied electrophysiologically in 12 adult albino rats with one eye removed at birth. For comparison, the contralateral projection was rather variable in the representation of the nasotemporal axis of the retina along the rostrocaudal dimension of the colliculus; on the other hand, the representation of dorsal-to-ventral retinal axis onto the mediolateral dimension of the colliculus was relatively stable.
