Document Summary
Identifying the causes of behavior: what causes emotional and motivated behavior, biology, evolution, and environment, neuroanatomy of motivated behavior, stimulating emotion, control of regulatory behavior, control of nonregulatory behavior, neuroanatomy of motivated behavior, critical structures. Hypothalamus and associated pituitary gland: sends information to other brainstem circuits to produce behavior. Funnel metaphor: hypothalamus critical in maintaining homeostasis. Process that maintains critical body functions within a narrow, fixed range. Body wants balance: regulatory and nonregulatory behavior, regulatory behavior. Behavior motivated to meet the survival needs of the animal. Controlled by homeostatic mechanisms (detecting mechanism), which involve the hypothalamus. Thermostat mechanism: detects if temp drops and brings back to certain temp. Internal body temperature: eating and drinking, salt consumption, waste elimination. Nonregulatory behaviours: behaviour unnecessary to meet the basic survival needs of the individual animal, not controlled by homeostatic mechanisms, most involve the frontal lobes more than the hypothalamus. Newer behaviors (evolutionarily) as frontal lobes developed last: strongly influenced by external stimuli, examples:
