Receptive field mechanisms of ganglion cells in the cat retina

Receptive field mechanisms of ganglion cells in the cat retina

On the basis of anatomical and physiological results of the vertebrate retina, a method is proposed for analyzing the respective fields of ganglion cells in the cat retina. In the model, the following was assumed: Ganglion cells receive their input from bipolar and/or amacrine cells; the nonlinearity of ganglion cell responses is due to the activities of transient type amacrine cells. The method proved to be effective. According to the results of this investigation, the receptive field properties of X type and Y type ganglion cells are heterogeneous. Apparently, their receptive fields consist of center and surround mechanisms. The receptive field properties of X-cells are almost linear, and the X-cells seem to receive most of their input from bipolar cells. The ones of Y-cells are highly nonlinear. Consequently, it is conceivable that the Y-cells receive their input mainly from transient type amacrine cells.
