Response Dynamics Of Retinal Ganglion And Early Visual Cortical Cells To Simulated Optical Blur, Michael Lance Risner

All ETDs from UAB

Visual neurons are highly sensitive to changes in luminance around the mean level of light. The effects of changes in luminance contrast on the responses of retinal ganglion cells (RGCs) and V1 neurons have been extensively studied. Sharp transitions in luminance signify edges, which are key features in the visual environment. However, edges are rarely sharp and may be blurred. Edges are generally blurred because eyes have a restricted depth of field, sources of light are rarely point sources, edges are typically smooth, and rapid motion induces blur. The purpose of this research was to understand how RGCs and V1 …
