PSYC2007 Final: PSYC2007 Study Guide
Document Summary
Composed of two symmetrical hemispheres - left and right, connected by commissures, the largest is the corpus callosum. Inner hollow tube filled with cerebrospinal fluid (csf) cushions brain and removes metabolic waste. Cerebral cortex - outer layer of wrinkled tissue. Features of the cortex: gyrus/gyri fold/s of the cortex. Large sulci = fissures, eg: longitudinal fissure divides the two hemispheres: divided into four lobes, frontal lobe who we are as a person. Complex: thinking, emotional control, linking meaning to words: temporal lone - hearing, memory acquisition, object perception, parietal lobe - sensory integration, space perception, truth, motor control, proprioception, occipital lobe - initial visual processing. How brain related to rest of nervous system: cns brain + spinal cord, skull protects the brain vertebrae protects spinal cord, peripheral nervous system (pns) - fibres that carry information to and from the cns.
