Mapping Retinal Features in a Freely Moving Eye with Precise Control of Retinal Stimulus Position

摘要: The primate retina has evolved to cope with a diverse array of problems posed by complex natural environment. One solution employed the is regional specialization. At its center retinal fovea tightly packed cone receptors, exquisitely refined spatial acuity, and no rods. As one moves from into peripheral retina, visual acuity decreases rapidly (MILLODOT, (1)) along decrease in receptors an increase number only 20 degrees eccentricity, rods have reached their maximum density,and at more locations, density declines steadily (reviewed RODIECK (2)). Along these variations receptor populations, there are corresponding interneuron populations SNODDERLY (3)).
