BIOL 300 Lecture Notes - Lecture 17: Long Term Ecological Research Network, Lateral Geniculate Nucleus, Retina
Document Summary
Signals from the lateral geniculate nucleus arrive in the brain in the primary visual area (v1) and processing occurs as the signals work their way through a hierarchy of synapses back to the v2, v3, v4, v5, v6, v7, These signals percolate in two general directions into the brain from v1, one is ventrally in the temporal lobe and and the other is dorsally in the parietal lobes. The connection between the eyes, optic chiasm, and lateral geniculate those neurons send axons to the visual cortex. One of the things the visual system is really good at is making guesses as to the pattern of things you"re seeing and lling in where you don"t see very well. We don"t have fabulous resolution our visual system, only about a million axons coming through the optic nerves, and the resolution is not uniform across the eyes. We don"t see two black holes in our visual eld all the time because of completion.
