1.   But for the visual cortex, light flashes work pretty well.

2.   For example, our visual system maps visual space on to the surface of our visual cortex.

3.   In the case of the visual cortex, no one knows yet.

4.   Indeed, it is extremely difficult to distinguish between the primary visual cortex and surrounding areas in this species.

5.   It can also influence learned and voluntary reactions to visual stimuli when the visual cortex is absent.

6.   Matters are further complicated by the fact that information from the two eyes is brought together in the primary visual cortex.

7.   Part of the problem is that they are often on tasks that are also severely impaired after destruction of primary visual cortex.

8.   Surely, everyone thought, something fancy happened in those six layers, all of which send axons to the visual cortex.

9.   The strongest evidence for such a contribution comes from studying the effects of removal of the primary visual cortex.

10.   This suggests that the visual mechanisms involved in discrimination performance change after visual cortex ablation.
