c.ii.1. The level of glucose is noted by your liver which monitors
whether glucose has been deposited or not
c.iii. Signaling your brain
c.iii.1. The signals from your liver go to the hypothalamus
c.iii.1.a. If lateral hypothalamus stimulated-start feeding
c.iii.1.b. If ventromedial hypothalamus stimulated-stop feeding
c.iii.1.c. EXAMPLE- Rat with no ventromedial hypothalamus vs.
one with
