NROC64H3 Lecture Notes - Lecture 2: Amacrine Cell, Retina Horizontal Cell, Ganglion Cell
Document Summary
Synapse with either rods or cones: one group of bipolar cells receiving rod information and another receiving cone information and passes on info to the ganglion cells. Dendrites receive information from photoreceptors, and their axons transmit information to the ganglion cells: can be direct or indirect (via amacrine cells) Diffuse- receives input from up to 50 photoreceptors and pools it before passing it on to single source: characteristic of rod pathway, better for visual sensitivity. Midget- receives input from single source and passes it on to single source: characteristic of cone pathway, better for visual acuity. Cones: rf that are non-uniform can be on or off, half cells in signal in light (on, the other half cells convey signal when there is in the light (off) Rods: all of the on variety. Photoreceptors release glutamate to talk to bp cells. On bipolar cell has mglur6 receptors which is inhibitory. Off bipolar cells has ampa which is excitatory.
