Damage to the midbrain can result in a wide variety of movement disorders, difficulty with vision and hearing, and trouble with memory. Because the midbrain houses the hypothalamus, it also plays a major role in automatic body functions.
What does the diencephalon do?
The diencephalon is involved in many crucial bodily functions including coordinating with the endocrine system to release hormones, relaying sensory and motor signals to the cerebral cortex, and regulating circadian rhythms (the sleep wake cycle).

What makes up the mid brain?
The midbrain consists of various cranial nerve nuclei, tectum, tegmentum, colliculi, and crura cerebi. The hindbrain, also referred to as the brainstem, is made of the medulla, pons, cranial nerves, and back part of the brain called cerebellum.

What is the tectum of the midbrain?
Anatomically, the tectum is that portion of the mesencephalon, or midbrain, sitting between the hindbrain and the forebrain. The name is the Latin word for roof and reflects the view of early anatomists that the tectum formed a roof over the fluid-filled cerebral aqueduct and the tegmentum.
