PSYB65H3 Study Guide - Recapitulation Theory, Internal Carotid Artery, Lateral Sulcus
Document Summary
Psyb65 cumulative lecture notes weeks 1 11. Thalamus is the relay center to convey information into neocortex. Critical basic life processes occur in the brainstem mostly in medulla. Reticular formation plays a role circadian rhythm; sleep and wake cycles. Hypothalamus controls hunger, thirst, territoriality and sexual behaviour (if it feels good it"s there, 4fs) Size of a structure directly related importance of use and function in particular species. Ontogeny recapitulates phylogeny what an individual goes through in development (ontogeny) Limbic system plays a role in learning and memory, and emotion from conception to maturity is similar to process of species evolution. Maclean"s triune theory has 3 basic component, the human brain is 3 in 1: reptilian brain (the oldest and consist of brain stem up to thalamus), it still exists. There is evolutionary pressure for humans to be smarter. Human brains have sulcis (grooves) and gyri (convolusions)
