Functions of the Midbrain


The midbrain is mainly involved in the motor functions of the body such as vision, basic movements,
and hearing. A part of the midbrain called the substantia nigra plays a role in releasing
dopamine-producing neurons. Because the midbrain is involved in muscle movement, the death of
neural cells in the substantia nigra can lead to Parkinson's disease, a condition in which a person loses
voluntary control of the muscles and experiences body tremors.

The six sections of the midbrain are the:
-Tegmentum: consciousness
-Superior Colliculus: vision
-Inferior Colliculus: hearing
-Cerebral Peduncle: motor function
-Red Nucleus: motor function
-Substantia Nigra: motor function
