A RETROGRADE FLUORESCENT-LABELING STUDY OF DIRECT RELATIONSHIP BETWEEN THE LIMBIC (ANTERODORSAL AND ANTEROVENTRAL THALAMIC NUCLEI) AND THE VISUAL-SYSTEM IN THE ALBINO-RAT

Injecting different fluorescent tracers into the right anterodorsal (A D)/anteroventral (AV) or AD/AV and the primary visual nuclei of dorsal lateral geniculate (dLGN) or superior colliculus (SC), a direct proje ction from the left retina to these anterior thalamic nuclei was ascer tained in the central part of ventro-nasal retinal quadrant. Single-la beled cells were of small type. No double-labeled cells were demonstra ted.
