Document Summary

Parts of the eye: descriptions/functions/ associated disorders or problems for each part: d. the retina, 1. General description/function: photo pigments, rhodopsin (red, retinal molecule and opsin, the retina registers the presents of the object using rods and cones, 2. Collector cells: a. bipolar/horizontal/amacrine, b. retinal ganglion cells (retinal ganglia, right behind of the rods and cones, 4. The blind spot: at the back of the eye, not black but are just nothing there, 5. It has the highest ability to see fine detail. Why does this particular after-image occur: neurons, when something is on white, it means the cells looking at it will produce a lot of ap and the collector cells are getting that ap. Two ways that collector cells summarize information: rods and cones, many rods are connected to the ganglion cells, summation, a. convergence and spatial (lateral) summation, 1. Effects of summation (review: adding up the activity in many neurons, b. lateral inhibition, 1.
