Question

What is one reason why animals with a lesion in the lateral hypothalamus eat so little?

Answer 1

The hypothalamus is the part of the brain where the activity of the autonomic nervous system and the endocrine glands, which control various systems in the body.

If there is an injury in one of these parts, they tend to have difficulty eating
The metabolism of carbohydrates is accommodated within the scheme of regulation hypothalamic appetite, glucose sensitive structure.
A glucoreceptor mechanism hypothalamic has been postulated. The ingestion of food or the administration of intravenous glucose produces electrical activity in the hypothalamic ventromedial region. The use of glucose is based on an arterio-venous difference.Conversely, food deprivation produces hypoglycemia decreasing the electrical activity in the hypothalamus, simultaneously the electrical activity in the lateral hypothalamus tends to vary in the opposite direction. The amount of sugarin the blood decreases and seems to be a major determinant in the hypothalamic response.
