PS102 Lecture Notes - Lecture 5: Occipital Lobe, Visual Cortex, Temporal Lobe
Document Summary
Black or white: stare at certain colour, neural processes become fatigues, have rebound" effect with receptor responding with its opponent opposite reaction. Retinal ganglion cells: project information from the retina to the brain via the optic nerve, are arranged in opposing cells: red-green, yellow-blue, black-white. Support for this theory- we cannot see mixes of certain colours: reddish green or bluish yellow. Dual process theory: combines trichromatic and opponent-process theories (picture) The optic nerve carries messages from each eye (visual field) to the visual cortex (occipital lobe)- arrangement of crossing is to use both left and right hemispheres of our brain. The optic nerve contains the axons of 1 million ganglion cells: that exit the eye via the blind spot, and project to the thalamus. From the thalamus, neurons project to the visual cortex (what happens if visual cortex is damaged, won"t be able to transform the sense into a signal)
