PSYB65H3 Lecture Notes - Chopsticks, Caudate Nucleus, Cerebral Achromatopsia
Document Summary
We talked about how ns put together and what can go wrong w/ it. Sensory system is in parietal cortex and motor fxn in frontal cortex, divided by central sulcus and on either side of the sulcus are the gyri. Post-central gyrus = primary sensory input from body other than special senses. What happens when those areas get damaged (stroke, tumor etc;) Visual system = specialized = occipital cortex at back of head. Temporal lobe & auditory cortex = primarily hearing but also speech (understanding language, decoding and re-encoding and making language) To get to the 2 separate parts of the brain, the optic chiasm separates apart and goes into brain; part where they are separating and going to back = optic tract. Group of axons that come together: if outside the cns = nerve; inside. Nerves from temporal (outside) portion of each retina remain on same side and go up to cortex.
