Document Summary

Vision 2: primary visual cortex: from eye to brain (lecture 6, primary visual cortex (lecture 6-7, from eye to brain (lecture 6) Broad outline of how visual info is carried to the primary visual. The optic chiasm is where nerve fibres from half of each retina cross over to the opposite side of the brain. Information from the nasal part of the retina will cross to the other side; the lateral part of the retina will stay on the same side, and this is how the left and right visual fields are separated. If you completely lesion the right optic nerve: the right eye no longer sees the left or right visual field, but the left eye can still see the left or right visual field. The nasal part of the retina is looking to the right visual field, and it"s the part that crosses to the left part of the brain.
