Abstract





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. l'hes,_rcsults 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.

Key words: orientation sensitivity;organized arrangement;lateral geniculate nucleus;dark-reared cats
