Contribution Of Retinal Ganglion Cells To Brown-Norway Rat Spatiotemporal Visual Perception And The Electroretinogram, Nicholas P. Johnson
USF Tampa Graduate Theses and Dissertations
Retinal Ganglion Cells (RGCs) are the sole cells through which visual information is transmitted from the eye to the brain. As such, RGC dysfunction has a dramatic effect on vision and perception. Retinal neurodegenerative diseases, such as glaucoma, are one of the leading causes of blindness worldwide. The study of these diseases requires well-characterized models in order to swiftly and effectively develop diagnostic tools and therapeutics. This dissertation aims to characterize specific properties of the visual system of the Brown-Norway rat. First, visual processing was evaluated in awake, freely moving rats. Contrast sensitivities of Brown-Norway rats were characterized by discrimination-driven …
