The midbrain acts as a relay station for auditory and visual information (Kumar, 2012). Not only does the midbrain control auditory and visual systems, it also controls eye movement. The midbrain has two main parts the tegmentum and the tectum. The Tegmentum is located within the brainstem and forms the base of the midbrain.The tegmentum consists of the reticular formation, periaqueductal grey matter, and the red nucleus. The reticular formation is involved in sleep, arousal, attention, and other basic reflexes. The periaqueductal grey matter controls instinct movements such as fighting and mating. The red nucleus helps with motor coordination. The tegmentum, altogether controls motor functions, regulates awareness and attention, and regulates a few autonomic functions (NINDS, 2015). The tectum is located towards the back of the midbrain. It has two parts, the superior colliculi, and the inferior colliculi. The tectum controls the auditory and visual responses. The colliculi are responsible for processing visual information from the ears and eyes. The superior colliculi processes visual information then relays it to the primary visual cortex which is located in the occipital lobe. The inferior has a different job, which is to process auditory information before the information is relayed to the primary auditory cortex (Davies,
