Document Summary
Where dopamine cells are produced important in drug use. Spinal cord, hindbrain breathing, heart rate. Forebrain thinking, humans have much more surface area in forebrain. A lot of research on brain effects is based on animal research. Dopamine cells control how drug is active. Effects differ from one species to the next. Reticular formation wake up cells and allow them to function, center for arousal. Pons relay info from brain into spinal cord. Responsible for a lot of drug taking behavior and reward. Superior colliculus, inferior colliculus send info for processing. Hypothalamus connects thalamus to pituitary gland. Ventral tegmental pathway (vta) role in reward (addiction) and schiz. Passes into nucleus accumbens processes reward and info. Tells you that you like something and that you should go get something. Stimulates cells to produce acts to go acquire the drug motor cortex. Substantia nigra is main cell groups for da production in whole brain, implicated in movement.
