Connectivity of Retinal Projections in Uniocular Mice
The ipsilateral retinal projections to the dorsal lateral geniculate nucleus (dlGn) and to the superior colliculus have been traced in mice either enucleated unilaterally at birth, or bearing a congenital monophthalmy that occurs in the early embryonic life. In both cases, the uncrossed pathway spreads to deafferented regions in the dlGn and superior colliculus. In the dlGn, however, it does not reach the lateral and dorsal borders of the nucleus, and in the superior colliculus only the rostral half contains uncrossed projections. The projections to the superior colliculus are mostly found in the stratum opticum and in the upper stratum griseum superficiale, where they are frequently fragmented in patches of high density of projection.
