The results of this experiment strongly suggest that there is a connection between eating behavior
and the activity of these two regions of the hypothalamus
The rat on the left had the ventromedial hypothalamus destroyed and it became very fat
The rat on the right had the lateral hypothalamus destroyed and it lost a great deal of body weight
But the sugery does not seem to have removed the rats ability to feel hungry or feel satisfied
After a period of adjustment, each of these rats showed a pattern of eating and body weight
That had stabilized around a new higher or lower body set point suggesting
that the VMH and LH are links in a complicated set of brain networks that regulate food consumption.
