Document Summary
Cerebral hemispheres make up the most of brain, for a rat there"s more of the sub regions below hemispheres b/c they don"t absorb a lot of info but need to control organs and muscles. Superficial cortical layer of gray matter containing neuronal cell bodies. Thin grey (darker opaque) layer around surface of cross section. Must have major connectivity with rest of brain ex need to be connected to regions controlling muscles in tongue. Many connections just in cerebral cortex which allow us to do our intense thinking. Deeper layer of white matter containing fibers connecting cell bodies to other cortical areas and the rest of the brain. Basal ganglia - deepest layer of large collections of neuronal cell bodies. Cerebrum contains basal ganglia deep layer of neurons that have circuits with cerebral cortex to coordinate behavior functions. Sensory and motor areas simple + higher sensation and movements. Gyri (ridges) and sulci (grooves) provide anatomical separation of areas.
