Document Summary
Flourens: conducted experiments on rabbits and pigeons, depending on the region removed of the brain, the animals lost their ability to coordinate muscles, control breathing, or perform certain cognitive functions, brain keeps us alive. Cerebellum: motor movements, posture, balance, coordination, speech, etc. Cell communication: action potentials, axons shoot chemicals (neurotransmitters) across the synaptic cleft, these nt change the voltage of the next cell to continue the ap. Glia: tiny cells that make up the brain, supporting cells, clean up nearby molecules and neurotransmitters. Insulate axons with a fatty coating myelin sheath. Cerebrum: the brain tissue is wrinkly and folded on itself so it can fit all of the cells, gyri (gyrus) mountains of the folds, sulci (sulcus) valley. Amygdala: almond-sized areas roughly behind the temple, behavior linked to basic survival, (cid:862)fight-or-flight(cid:863) (cid:271)eha(cid:448)io(cid:396)s, emotional regulation. Hypothalamus: cluster of nuclei regulating hunger, sleep, and stress, sits under the thalamus ( - main relay station of the brain)
