Final answer:
The corpora quadrigemina is composed of the superior and inferior colliculi, which are involved in processing visual and auditory sensory information, respectively.
Step-by-step explanation:
The corpora quadrigemina is composed of superior and inferior colliculi. These are four prominences located in the tectum of the midbrain and they play a crucial role in processing sensory information. The superior colliculi are involved in visual processing and the coordination of eye movements, whereas the inferior colliculi are part of the auditory pathway and help in the perception of sound.
The inferior colliculus is part of the auditory brain stem pathway and projects auditory information to the thalamus for conscious perception of sound.
