Retinal Ganglion Cells Underlying Visual Perception And Predation In Mice, Keith Patrick Johnson
Arts & Sciences Electronic Theses and Dissertations
The spike trains of retinal ganglion cells (RGCs) are the sole source of visual information to the brain. In mice, more than 40 RGC types send signals to more than 50 brain areas. RGCs that perform nonlinear operations to extract specific visual features (e.g., the motion of an object against a background) are called feature detectors. Those that linearly integrate local changes in light inten-sity are known as pixel encoders. Most mouse RGC types are feature detectors. In the first part of my dissertation, I discovered a pixel encoder RGC type in mice, the PixON-RGC. I revealed how the unique …
