PSYB65H3 Lecture Notes - Middle Cerebral Artery, Arachnoid Mater, Visual Cortex
Document Summary
Corpus collosum is the pathway that connects the two hemispheres of the brain and allowing them to communicate with each other. Central sulcus is a very prominent groove. Sylvian or lateral fissure is the large fissure on the side. Brodmann mapped the cerebral cortex of the human, and put numbers on the areas; Homunculus- neurons for toes and feet are at the top of the brain, then hands, moving down to the body, then face on the sides of the brain. Paralysis refers to the inability to move not sense. Occipital lobe is at the posterior portion of the brain, just above the cerebellum; major function is vision and it receives information from the eyes; primary visual cortex is area 17; Temporal cortex is the in the ventral portion of the brain (on the side); ventral to the sylvian fissure; involved in hearing; primary cortex is area 41.
