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 (Pix<sub>ON</sub>-RGC). Pix<sub>ON</sub>-RGCs have medium-sized dendritic arbors and non-canonical center-surround receptive fields. From their receptive field center, Pix<sub>ON</sub>-RGCs receive only excitatory input, which encodes contrast and spatial information l ...[more]
