Document Summary
On center ganglion cells when center is bright and surround is dark. When light is in surround there is inhibitory response. When some of surround is lit but all of center is lit excitatory response. Oct. 17th: center surround comes from horizontal cells (gabaergic) Binocular visual field sees mostly what both the right and left eye see but it has a left monocular portion and a right monocular portion (a part which only the left or right eye can see) Left visual field activates nasal retina of left eye and temporal retina of right eye and vice versa for right visual field. Optic nerve (cranial nerve #2) only exists before chiasm (after optic chiasm axons are called optic tract) lateral geniculate nucleus is part of thalamus that received input. Lgn sends many axons (axons radiate and have a topography) hippocampus important for memory. Holes are ventricles and hold csf (cerebrospinal fluid)
