PSYB65H3 Lecture Notes - Corpus Callosum, Dura Mater, Basilar Artery
Document Summary
Psyb65 lecture 2: function of the cerebral hemispheres, brain vascular supply, Sulci: the valleys, the indentations dividing the brain. Burn on left hand is crossed over to the right side of the brain. Long tudinal fissure: very deep, dividing the left hemisphere from the right. Everything in the right is controlled and sensed by the left side of the brain and vice versa. Pathway connecting the two hemispheres is called corpus callosum* The cortex is divided into lobes, as well as hemispheres. Each lobe has two different types of cortex: primary cortex and associational cortex. Primary cortex deals with the primary thing that the lobe does. Primary cortex surrounded by the tissues further controlling the primary function called associational cortex associational cortex is able to process more complicated material. Broddman mapped the brain, numbering each part of the brain with numbers. The most anterior portion to the central sulcus.
