[Response of the receptive fields of the lateral geniculate body to temporal changes in the area of a light stimulus].
Neuronal responses of the cat LGB to light spots the area of which was changing in time with different speed, were studied. All the neurons responding to switching on and off of the test spot respond to changing in time of the spot area too. The on-neurons respond to enlargening of the area while the off-neurons - to its reducing. The on- and off-responses of these fields occurred at the moment of passing of the margin of reducing (growing) spot across a certain point of neuron's receptive field. This point changed when the speed of reducing (growing) of the test spot changed.
