Document Summary

Lateral inhibition: shining lights and measuring frequency of firing. All lights off and one bright spotlight, increase frequency of firing. If you have 3 receptors, the middle one higher will increase firing. If you excite one side, it goes down from max: middle shining gets max. Recoriding from visual cortex: electrical signal from brain generated from recording electrode from eyes to brain, hubel and wiesel. Retinal ganglion cell respond to spots of light. In cortex, response is to a slit of light. Simple cell: fires to a slit at a particular orientation on a specific retinal location, stationary, retinal ganglion cells. Has to be vertical line movement for the on center to work. They are arranged vertically, so they can only recognize vertical lines of light when shot vertically and this generates the maximum response i. e a vertical slit at a particular retinal address would hit all on centers. Complex cells: responds to moving slits at particular orientation.
