PSYB65H3 Lecture Notes - Lecture 2: Thalamus, Temporal Lobe, Subarachnoid Space
Document Summary
Human brain starts off smooth, through develop it pushes back and crunches together and folds upon itself. Central sulcus/fissure separates the brain anterior from pariotal (front/back) Sylvian sulcus/fissure (lateral) seperates out the temporal lobe. Right receives info from left hand side of body and controls it. Left receives info from right and controls it. Cerebal cortex has 4 lobes: each has major primary function. Within in each lobe two types of tissue (primary cortex, associational cortex) Primary cortex performs basic input/output functions (gets info from environment and processes it/acts) Each lobe has a primary area where basic input comes in. Associational cortex- higher order functions, more recently evolved, thought processing part of brain. Frontal - begins in anterior goes back up to central sulcus, involved in motor(muscle) movement, planning and inhibition of inappropriate behaviours (delayed gratification)precentral gyrus right infront of central sulcus , primary motor strip motor.
