Lack of binocularity in cells of area 19 of cat visual cortex following monocular deprivation.
We have studied the visual receptive field properties of neurons in cortical area 19 of monocularly deprived cats. Almost all visually responsive units responded to stimulation of the non-deprived eye only. Receptive field properties assessed through the non-deprived eye were found to be normal. Monocular deprivation appears thus to have sharply reduced the normal binocularity of neurons in area 19. Since the W-cell component of the visual pathways provide the predominant input to area 19, our results suggest that W-cells are vulnerable to environmental manipulation.
