Document Summary
Psya02 lecture 8 sex and eating. Hypothalamic centers in the brain monitoring appetite. Memory of time elapsed since last meal. Stomach contractions (pangs) send signals to the brain making us aware of our hunger. Lack of eating, empty digestive system low blood insulin, so little glucose enters cells; appetite increases eating fills digestive system, increases insulin level; more glucose enters cells appetite decreases, digestive system empties. This is a feedback system between eating and insulin levels maintains homeostatic control of nutrition. Memory plays an important role in hunger. Due to difficulties with retention, amnesia patients eat frequently if given food. This suggests that part of knowing when to eat is our memory of our last meal. Body chemistry and environmental factors influence not only when we feel hunger but what we feel hungry for! Social context of eating (more than just homeostasis)
