QUADRIGEMINA Meaning and Definition

1. Quadrigemina refers to a complex of four rounded protuberances or prominences found on the midbrain known as the colliculi, which are responsible for various sensory and motor functions. The two pairs of colliculi, collectively called the quadrigeminal bodies, are located on the dorsal side of the midbrain, specifically in the posterior region of the superior tectum.

   The quadrigemina are divided into two groups: the superior colliculi and the inferior colliculi. The superior colliculi, also termed the upper or posterior corpora quadrigemina, play a crucial role in processing visual information and regulating eye movements. They receive input from the retina and relay visual signals to various brain regions involved in visual perception and coordination of eye movements.

   On the other hand, the inferior colliculi, also known as the lower or anterior corpora quadrigemina, are primarily involved in the processing and integration of auditory stimuli. They receive input from the inner ear and relay auditory information to the auditory cortex, enabling the perception of sound and assisting in sound localization and auditory reflexes.

   Overall, the quadrigemina, as part of the midbrain, contribute significantly to sensory processing, integrating visual and auditory stimuli, facilitating visual-motor coordination, and imparting precise control over eye and auditory reflexes.

2. Corpora quadrigemina; see colliculus inferior and colliculus superior.
