The hypothalamus thus has widespread effects on the body and behavior, which stem from its role in maintaining homeostasis and its stimulation of hormone release.

Is hypothalamus located in midbrain?

The forebrain, midbrain and hindbrain make up the three major parts of the brain. The structures in the forebrain include the cerebrum, thalamus, hypothalamus, pituitary gland, limbic system, and the olfactory bulb. The midbrain consists of various cranial nerve nuclei, tectum, tegmentum, colliculi, and crura cerebi.
