Hello!!

In the brain, the corpora quadrigemina (Latin for "quadruplet bodies") are the four colliculi—two inferior, two superior—located on the tectum of the dorsal aspect of the midbrain. They are respectively named the inferior and superior colliculus. ... It basically connects the forebrain and the hind brain.

Hi there ,

Hope you're having a great day.

I would like to inform you that Corpora quadrigemina is the Latin terminology (https://www.kenhub.com/en/library/anatomy/anatomical-terminology) for the quadruple bodies, also known as the colliculi. These round eminences are located on the posterior surface of the midbrain, just below the t (https://www.kenhub.com/en/library/anatomy/thalamus) halamus. There are two superior and two inferior colliculi,with one of each sitting on either side of the midline. The entire region, consisting of the four colliculi, is known as the tectum, or tectal plate. The superior colliculi play an important role in the visual pathway, while the inferior colliculi are important in the auditory pathway.

If you have any further questions just let me know in the comments section below, Ill help you out as soon as possible.

Thanks a lot and best of luck for your future ahead.

Hello Kumar Gaurav,

The corpora quadrigemina are reflex centers involving vision and hearing. It consists of groups of nerve cells-grey matter scattered in white matter. It basically connects the forebrain and the hind brain. It has four corpora quadrigemina which are the reflex centres of eye movement and auditory responses. The superior part of corpora quadrigemina are called superior colliculi, and inferior part as inferior colliculi.

Hope this helps you...
