PSYB65H3 Lecture Notes - Lecture 2: Posterior Cerebral Artery, Central Canal, Meddle
Document Summary
As the human brain develops, it start up smooth! and eventually grows! because of the high number of dendrites and tissues! therefore they form gyrus (highly folded) Sulcus (sulci ) the vallies! if they are really huge they are called fissure! Gyrus are the mountains! right side of the brain receives information from the left side of the body! Longitudinal fissure divides the two hemispheres into right and left! The two hemispheres are connected and interchange information! not directly on the top! Collusum! the fiber pathways cross over the corpus collusum! it goes straight through! There are three main sulci: 1) longitudinal fissure 2) central sulcus (fissure) frontal lobe and parietal lob 3) sylvian sulcus runs up the side of the brain and it separates out the temporal lobe. Cerebral cortex has 4 lobes => 1) frontal 2) parietal 3) temporal 4) occipital. Each lobe has one major primary function!
