00:00:05.000 --> 00:00:11.000
The results of this experiment strongly suggest that there is a connection between eating behavior

2
00:00:11.000 --> 00:00:16.000
and the activity of these two regions of the hypothalamus

3
00:00:16.000 --> 00:00:22.000
The rat on the left had the ventromedial hypothalamus destroyed and it became very fat

4
00:00:22.000 --> 00:00:29.000
The rat on the right had the lateral hypothalamus destroyed and it lost a great deal of body weight

5
00:00:29.000 --> 00:00:36.000
But the sugery does not seem to have removed the rats ability to feel hungry or feel satisfied

6
00:00:29.000 --> 00:00:42.000
After a period of adjustment, each of these rats showed a pattern of eating and body weight

7
00:00:42.000 --> 00:00:47.500
That had stabilized around a new higher or lower body set point suggesting

8
00:00:47.500 --> 00:00:56.000
that the VMH and LH are links in a complicated set of brain networks that regulate food consumption.
