Document Summary
Drives: restoring homeostasis and avoiding painful states of tension. The body"s ability to physiologically regulate its inner environment to ensure its stability in response to fluctuations in the outside environment and weather: self regulation: temperature energy. Thermal regulations: in hypothalamus in immediate situations or in anticipation. Dual center theory: hypothalamus = go center for eating; ventromedical region = stop center o (simplified) Hypothalamus is only one of go centers for feeding. Why so many cues: safety (back-up systems) Psyc w1001: different aspects of nutritional needs, different roles in overall control of feeding. Cues to make other cues more persuasive (potentiate) What else contributes to eating: culture, memory (cid:0) hungry. Less sensitive to leptin, vulnerable to npy: efficiency in digestive apparatus (extract more calories, metabolic level: less nutrient fuel burned up, more fat stores. Critical physiological process to make sure we"re getting enough energy o. Size of plate: cultural factors (affect eating behaviours)
