  • When Neuropeptide Y is injected into the hypothalmus of rats it causes overeating

4. Which does neuropeptide Y do in terms of controlling eating behaviour?

  • It's produced by fat cells and impulses are sent to the brain about the amount of fat cells present, obese rats have a high levels of leptin
  • It stimulates the hypothalamus increasing appetite
  • It stimulates the hypothalamus decreasing appetite
  • It's produced by fat cells and impulses are sent to the brain about the amount of fat cells present, obese rats have a deficiency in leptin
