  1. Brain Signaling for Food By George Han, Sean Feng

  2. INTRO • Essential part of life, nutrition, vitamins • Brain signals the quantity intake of food • Affected by smell, sight, and memory • Brain turned on by taste and emotion

  3. Hypothalamus signals nerves in the stomach • Determines specific appetite • Amino acids (protein), fatty acids (fat), glucose (carbohydrates) • Insulin hormone sends brain message

  4. Low glycogen level/Low blood sugar level • Stimulate activity in hypothalamus • Increasing sweet/starchy food desire • Ghrelin/Leptin circulation • NPY • Different types of food • Sweet/Starchy • High calories • Fat food

  5. Leptin levels increase= cause of fullness • Inhibit firing of NPY • Galanin fat connection • Stores up fat • Evening • Enough calories to last through night

  6. Food digested feeds body cells • Chlecystokinin (CCK) • Causing fullness, less appetite • Bulimia • Over eating disorder • Binge purge syndrome • CCK mechanism doesn’t function • Anorexics • Suffering from extreme thin • CCK mechanism is oversized

  7. To sum up… • Human body has a complex system that signals our body for hunger. • Brain plays a big part of our survival instinct. • Bulimia and anorexia are caused by CCK malfunction.
