Where is the pineal gland located in the brain?
Quick Answer
The pineal gland is deep in the center of the brain, near the thalamus and between the two hemispheres. It is best known for producing melatonin, which helps regulate sleep cycles.
The Full Story
The pineal gland is a small endocrine structure located near the center of the brain, attached to the roof of the third ventricle and close to the thalamus. It lies between the two hemispheres in a region called the epithalamus. The gland secretes melatonin, a hormone involved in circadian rhythms and sleep timing. Its role in biological timing made it famous long before modern neuroscience identified its exact anatomy and function.
