摘　　要：Since Levick et al. found and studied the orientation biases of retinal ganglion cells of cats, there has been increasing interest in subcortical orientation sensitivity. Shou et al. studied the orientation sensitivity of dorsal geniculate nucleus (LGNd) relay cells of the cat in details. They found that cells with similar preferred orientation are clustered in the LGNd, which is apparent for all cell types (ON, OFF, X, Y) and cells with different receptive field locations in retina. It is suggested that the initial sorting of orientation functional columns in the visual cortex may begin in the LGNd.
