Document Summary

Note: when the light flashes below where the person is looking, it lights up vi about the calcrine but then it lights up two other areas above the calcrine, those areas are called v2 and v3. From v1 (primary visual cortex) information is sent to higher order visual areas, first v2 and then to. V3: v1 is around the calcrine, v2 & v3 are both above and below the calcrine. The calcrine is a deep valley: around it, is v2 and around v2 is v3. Lateral side (outside of the brain) you can hardly see v1 but you can see v2 and v3. In each area the retina is re-represented 3 times, once in each area v1, v2, v3. Note: the diamond is seen in the right lower visual field and is represented in the left upper v1. It is represented 3 times, once in each area v1, v2, and v3.
