Lipid metabolism in rats with isolated medial hypothalamus.

: Based on determinations of the serum total cholesterolemia, triglyceridemia, free fatty acids and obesity Lee index, performed in rats with isolated medial hypothalamus--VMH included--which had either free food access, or after 24 hours of starvation, or maintained on limited food intake, it has been concluded that the VMH nucleus is involved in the control of lipid metabolism especially through its inhibitory action on the lateral hypothalamic parasympathetic area.
