title: Thalamic afferents to the visual cortex in congenitally anophthalmic mice.
abstract: Retrograde cell labelling with horseradish peroxidase (HRP) has been used to study the thalamic afferents to the primary visual cortex (area 17) in mutant H1-ZRDCT-An ('eyeless') mice, in which the eyes are missing throughout development. Injections of HRP that were localised to a subregion of area 17, resulted in the labelling of a group of neurons in the ipsilateral dorsal lateral geniculate nucleus, showing the existence of a point-to-point connectivity. Many labelled cells were also found in other posterior thalamic nuclei especially in the lateral posterior nucleus which in normal animals contain very few or no labelled cells.
