Summary: The spike trains of retinal ganglion cells (RGCs) are the only source of visual information to the brain. Here. we genetically identify an RGC type in mice that functions as a pixel encoder and increases firing to light increments (PixON-RGC). PixON-RGCs have medium-sized dendritic arbors and non-canonical center-surround receptive fields. https://www.themightyhobbyers.shop/product-category/mystery-minis/
