Document Summary

Motivation = biological & psychological processes that compels us to act to achieve essential. Drives = stimulation that our brain generates to push us to address basic biological needs. Homeostasis = processes that allow us to maintain balance in our biological systems. Allostasis = processes that allow us to develop a state of readiness for anticipated future. Signal that gives us drives of things like hunger, originate in the hypothalamus demands on our biological systems. Signal to stop eating comes from the ventromedial region of the hypothalamus. Satiation = the experience of being full and uninterested in eating anymore. The hypothalamus receives info about glucose levels based on messages sent by special. Damage here causes overeating - and obesity neurons called glucostats sense a drop in glucose. When we eat, expansion of our intensives stimulates neurons to release cholecystokinin (cck) When the hypothalamus detects enough cck, it stimulates feelings of satisfaction.
