| Abstract(in English) | Fixation, holding one's eyes on an object, plays a key role in the perception of visual scenes. The miniature fluctuation, microsaccades, drifts and tremors, are involved in the fixation even the eyes seem still. Although the functional roles of the miniature eye movements have gradually been uncovered, the detail of those still remains mysteries. Here, we constructed a large scale visual system model to investigate contribution of the miniature eye movement on the visual functions -especially focusing on the processing in the retinal photoreceptors. The model consists of brainstem (eye movement control), eye optics, and photoreceptors; and those models are constructed based on the known anatomical and physiological evidence. We simulated fixation of the several scenes using the constructed model and evaluated photoreceptor responses by information rate. We confirmed that the information rate for the photoreceptor responses was increased with the miniature eye movement, while it was decreased without miniature eye movement. We also confirmed that increasing of the information rate resulted from increasing the responses for the edges of objects by the miniature eye movement. These results suggest that visual information is already enhanced at the retina level by miniature eye movement. |
