PSYB65H3 Study Guide - Final Guide: Reuptake, Plantar Reflex, Brainstem
Document Summary
Nervous system: central nervous system = brain + spinal cord, peripheral nervous system = nerves. Little difference between the brain and the spinal cord: they are one. 3 major classifications of the brain: hindbrain. Controls functions that keep the individual alive: eating, drinking, fighting for food, sexual reproduction. Limbic system: number of brain structures (not a single structure) Animals with larger limbic systems have increased emotional repertoire. Cerebral cortex- part of forebrain i. e. dog vs turtle: also known as neo cortex (newest part of brain) Dolphins have the biggest cortex: responsible for intellectual function. Cerebral cortex was a huge change in evolution allowing for intelligence the size of a brain structure that controls a function is directly proportional to the need of that organism. Ontogeny recapitulated phylogeny: your development mimics that of your development as an evolutionary species. Most anterior structure of the brain= cortex: covers up the whole brain. Found even as far back as reptiles.
