A Unified Mathematical Model for the Non-Classical Receptive Field of Ganglion Cells in the Retina

摘要

A mathematical model for receptive field of retinal ganglion ceil is proposed. This model includes the effect of the non-classical receptive field, which is resulted from the cross-inhabitation between the amacrine cells. This model also concerns the nonlinear effect of the photoreceptors so that unifies the X and Y ganglion cells. The null-test response of the X celt, the on-off response of the Y cell, spot-area response curves and spatial frequency tuning curves of the X and Y cells are all simulated successfully. These results show that the non-classical receptive field is important on the spatial frequency response of the retinal ganglion cell.
