In this study, we performed a simulation experiments using a mathematical model of retina considering peripheral characteristics to evaluate the influence of fixation eye movements. Recent studies indicate that drifts and tremor enhance particular spacial frequency components, and microsaccades emphasize the difference of contrast on the visual stimuli. However, the influence of fixation eye movements on the retina, especially on the peripheral retina, is not elucidated. The proposed model considers the distribution function of cone cells and reproduces the property of increase in the size of peripheral receptive fields of ganglion cells. The simulation results show that drifts and tremor enhance the response of ganglion cells for high spatial frequency input, and microsaccades enhance the response for low spatial frequency inputs. These trends are more prominent for in the M-type ganglion cells at some distance from fovea. Furthermore, it suggests that fixation eye movements might derive a synchronous fluctuation on the response of ganglion cells. |
