PSYB65H3 Study Guide - Gwn7, Dorsal Root Of Spinal Nerve, Lateral Geniculate Nucleus
Document Summary
1. diencephalon (sensory/motor info) thalamus: gateway for channeling sensory info traveling to cerebral cortex relays info btw cortical areas relays info btw forebrain and brainstem e. g. optic tract info to lateral geniculate nucleus processes info and sends to visual region of the cortex in each hemisphere: hypothalamus: controls production of hormones, interacts with pituitary gland. 2 types: new: neocortex (only mammals) and old: limbic cortex (chordates, mammals) neocortex creates perceptual world so you can respond to the world limbic cortex controls motivational states cortical lobes: occipital lobe: visual (shape/color, parietal lobe: tactile c. d. temporal lobe: visual (faces), auditory, gustatory frontal lobe: motor/executive because it integrates sensory and motor functions and formulates plans of action cortical layers neocortex is made of 6 layers of gray matter on top of a layer of white matter each layer has diff types of cells density of cells in each layer varies diff in appearance relate to functions of cortical layers in diff regions.
