Abstract: Single unit recording of cells in the lateral geniculate nucleus (LGN) of adult cats following monocular paralysis of two weeks duration has been reported to diminish the relative proportion of X-cells in this nucleus. This functional loss of LGN X-cells was detected in the LGN laminae innervated by the paralyzed eye. Limitations in the method of classifying LGN cells as X or Y in the earlier work, however, precluded acquisition of data concerning the proportion of X- and Y-cells in the laraina innervated by the normal eye. The present study used response latency to optic chiasm shock of LGN cells (OX latency) to divide cells as X or Y. Y-cells have short and X-cells long OX latencies. This measure allows analysis of the effects of monocular paralysis in the layers innervated by the paralyzed and mobile eye, respectively.
