Receptive field of ganglion cells

http://www.scholarpedia.org/article/Receptive_field WebbON ganglion cells have a receptive field centre that is activated by a light increase, OFF ganglion cells are activated by a light decrease in the receptive field center. These response characteristics are determined by their input neurons.

A midget cell is one type of retinal ganglion cell (RGC). Midget cells originate in the ganglion cell layer of the retina, and project to the parvocellular layers of the lateral geniculate nucleus (LGN). The axons of midget cells travel through the optic nerve and optic tract, ultimately synapsing with parvocellular cells in the LGN. how to draw princess bubblegum

Webb7 juli 2012 · By this measure, W3 cells have small receptive field centers, 120–160 μm in diameter, smaller than those of other ganglion cells in the mouse retina (Fig. 5C). Note that the receptive field for Off responses is systematically smaller than that for On responses. WebbGanglion Cells in the Parvocellular Pathway Receive Input from a Few Bipolar Cells Some ganglion cells receive inputs that are equivalent to a single or just a few bipolar cells. This small receptive field allows the ganglion cell to encode fine details of the visual field.
