Q. Basic working of Midbrain?
Midbrain: Also known as the mesencephalon, this part is located behind the frontal lobes and in the center of the entire brain. It deals with functions such as hearing, vision, body and eye movements. The midbrain can be divided into three parts called the tectum, tegmentum and cerebral peduncles. The midbrain is the smallest region of the brain that acts as a sort of relay station for auditory and visual information. The midbrain controls many important functions such as the visual and auditory systems as well as eye movement. Portions of the midbrain called the red nucleus and the substantia nigra are involved in the control of body movement. The darkly pigmented substantia nigra contains a large number of dopamine-producing neurons. The degeneration of neurons in the substantia nigra is associated with Parkinson's disease.
