Document Summary

Drive: biological trigger that tells us we need something, and therefore causes us to seek what is required. Motivation: physiological and psychological processes underlying the initiation of behaviours that direct one towards a certain goal. Contributes to homeostasis, physiological processes that maintain a consistent internal state. Influenced by allostasis, physiological processes that anticipate future needs. This ability is flawed, and affected by psychological processes. (cid:862)o(cid:374)(cid:863) a(cid:374)d (cid:862)off(cid:863) s(cid:449)it(cid:272)h for hunger is the hypothalamus. Lateral hypothalamus is the on switch, while ventromedial hypothalamus is off. Regulates level of glucose, a sugar that serves as a primary energy source for the brain and rest of the body. This regulation is an example of a negative feedback loop. Satiation: the point during a meal when one is no longer motivated to eat. Lots of brain areas are involved in this; when you eat a food to the point where you get sick of it, the reward center is no longer involved.
