The midbrain is the topmost part of the brainstem, the connection central between the brain and the spinal cord. There are three main parts of the midbrain – the colliculi, the tegmentum, and the cerebral peduncles. Of the 12 cranial nerves, two thread directly from the midbrain – the oculomotor and trochlear nerves, responsible for eye and eyelid movement.
At the top of the midbrain are the colliculi, which derives its name from the Latin word for ‘hill. It contains two pairs of bulging, layered bundles of neurons called the superior and inferior colliculi.
The tegmentum (Latin for ‘hood’) actually stretches down the length of the brainstem, but a portion of it forms a part of the midbrain. It contains two areas named after specific colours: the iron-rich red nucleus (which actually looks pink) is involved in the coordination of movements; the periaqueductal grey is a dense region of grey matter and is involved in suppressing pain.
The back of the midbrain contains a pair of large nerve fibre bundles that connect the rest of the brainstem to the forebrain.
These cerebral peduncles are the main highway for signals that need to be transported from the cortex to other parts of the central nervous system (CNS), and are especially important for body coordination.
What is the main function of the midbrain?
Midbrain, also called mesencephalon, region of the developing vertebrate brain that is composed of the tectum and tegmentum. The midbrain serves important functions in motor movement, particularly movements of the eye, and in auditory and visual processing. It is located within the brainstem and between the two other developmental regions of the brain, the forebrain and the hindbrain; compared with those regions, the midbrain is relatively small.
