Neural Mechanisms

1. Geneticallt manipulated mice so they didn't produce NPY. Found no decrease haviour compared to normal mice. Suggest injections may simply be an experimental side effect and cause behaviour that doesn't translate into real world settings (5, 2, 2)
2. For hunger to be adaptive, must be able to anticipate and prevent energy deficits, not just react to them. __________ commentary (11)
7. Injected NPY into hypothamus of rats. Caused them to immediately begin feeding even when satiated (7)
9. Amgdada- selection of foods on basis previous experiances. Inferior prefrontal cortex- recieves messages regarding smell. If damaged, can affect taste of food. (6, 10)
10. Lutter et al. Found body produced extra ghrelin when stressed. Associated with a boost in appetite and comfort eating (6, 3, 6)

2. Hypothamuls is gland responsible. Boy's tendancy to maintain constant internal state. Decline in glucose levels activates LH. Rise in glucose levels activates VMH\ (11)
3. Damage to ___ causes animals to overeat (hyperphagia). Situlation of ___ inhibits feeding and gives feelings of satiation. PVN damage alone causes hyperphagia (3)
4. Repeated injections of NPY into hypothamuls of rats produces obseisty in just a few days (7, 2, 2)
5. Surgically removed amygdada in rats. Found they would consume both famular and novel foods indiscrimantley (5, 3, 5)
8. Ethics. Determinist. Reductionist. (4)
