What do you mean by tectum?

The anterior commissure, on the other hand, connects the two cerebral hemispheres, enabling the exchange of information between them. The corpora quadrigemina, as a whole, contributes significantly to the integration of sensory information and motor output.

A bodily structure that serves as a protective covering, resembling a roof, is typically referred to as a cranial vault or simply a skull. It encapsulates the brain and provides structural support for the facial features.

Within the cranial vault, the dorsal part of the midbrain holds significant neurological importance. This region, often referred to as the tegmentum of the midbrain, houses vital nuclei and fiber tracts that facilitate communication between the forebrain, hindbrain, and spinal cord.

Among these structures within the dorsal midbrain, the corpora quadrigemina stands out. This quadrate group of four rounded elevations, located at the superior aspect of the midbrain, is comprised of the superior and inferior colliculi as well as the posterior and anterior commissures.

The superior colliculi are involved in visual reflexes and eye movements, while the inferior colliculi play a role in auditory processing. The posterior commissure connects the left and right halves of the midbrain, facilitating communication between them.
