[Topographic relationship of orientation sensitive relay cells in lateral geniculate nucleus (LGN) of dark-reared cats].
The orientation sensitivity of the LGNd neurons of dark-reared cats were investigated. As in normal cats, most of the cells studied were significantly sensitive to the orientations of grating stimuli (Bias > 0.1), and preferred horizontal and/or radial orientations. Also the adjacent cells tended to assume similar preferred orientations. These results indicate that visual deprivation in cats neither affect the distribution properties of preferred orientations, nor the clustering of cells with similar preferred orientations in the LGN.
