Document Summary

Next time: perception (scan p. 152-158; 170-176) Horizontal cells in the layer between the bipolar and receptors, amacrine between bipolar and ganglion (both inhibitory) Rods: operate at low intensity, sensitive for brightness, none in the fovea (in peripheral they are densely packed, monochrome (black & white, no colour) Cones: operate at higher intensities, insensitive for brightness don"t work for low levels, concentrated in fovea, full colour. Chemical in rods and cones that break down exposure to light (visual pigment) Cones: chlorolabe (green, erythrolabe (red, cyanolabe (blue) How to demonstrate this: dark adaptation, spectral sensitivity. Project spot of light on screen & move until output maximum. This is retinal area serves by that ganglion cell.
