Explanation:

Midbrain: The midbrain of a human being's brain is also referred to as mesencephalon and is considered as the developing vertebrate region of the brain which is composed of tegmentum and tectum. It comprises three distinct parts including cerebral peduncles, the colliculi, and the tegmentum.

Function: Motor movement including eye movement, visual, and auditory processing.

Any damage or malfunctioning to the midbrain of an individual causes vision difficulty, movement disorders, hearing difficulty, and memory trouble.
