Document Summary
Somatic interventions: manipulating the brain and body directly. Behavioral interventions: manipulate behavior to see how it affects the brain. Correlational studies: measure two different variables; somatic or behavioral. Apical dendrite lots in the hippocampus. Shape can change through learning and memory. Dendritic arbors can receive lots of signals. Astrocytes: large glia cells, 1) help to form the blood brain barrier by connecting to blood vessels, removing nutrients and transferring them to neurons. Cns vs. pns: cns contains brain and spinal cord pns is everything else. How is the brain protected: ventricles, meninges. Mechanisms of action: agonist vs. antagonist, competitive vs. noncompetitive. Classes of drugs: psychiatric disorders, alcohol, cannabis, nicotine, cocaine, methamphetamine, hallucinogens, ecstasy. Brain development: proliferation, migration, differentiation, process growth and synaptogenesis, cell death, synaptic rearrangement. Exogenous vs. endogenous control of circadian rhythms: external cues, superchiasmatic nucleus. Endocrine glands: anterior vs. posterior pituitary, adrenals, gonads. Two major stress responses: fast response (sympathetic-adrenal-medullary, slow response (hypothalamus-pituitary-adrenal)
