Termination of geniculocortical afferents on bipolar neurons in area 17 of the albino rat: a Golgi/EM study.

Degenerating terminals of specific afferents to the primary visual cortex of the albino rat were identified by electron microscopy after electrolytic lesions of the lateral geniculate nucleus. Bipolar neurons were marked by Golgi impregnation. We observed smooth dendrites of two bipolar cells postsynaptic to degenerating geniculate terminals. We conclude that this cortical cell type is directly contacted by thalamic afferents.
