Document Summary
The visual pathway: rods and cones pass their signals to the bipolar cells, which relay them to the ganglion cells (4. 26). The axons of ganglion cells form the optic nerve, which leaves the eyeball and begins the journey toward the brain: ganglion cells, for example, can be broadly classified into 2 categories. Smaller ones called parvo cells ganglion cells that, because of their sensitivity to differences in hue, are particularly suited to perceiving color and form. Play crucial role in our perception of pattern and form. Larger ones called magno cells ganglion cells that, because of their sensitivity to brightness changes, are particularly suited to perceiving motion and depth. Play central role in detection of motion and perception of depth. Parallel processing in the visual cortex: cells in visual cortex seem to have a preferred stimulus and each cell fires most rapidly whenever this special stimulus is in view.
