The inferior colliculi of the midbrain are located just below the visual processing centers known as the superior colliculi. The inferior colliculus has three subdivisions – the central nucleus, the dorsal cortex by which it is surrounded, and an external cortex which is located laterally. [1]
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. The corpora quadrigemina are reflex centers involving vision and hearing.
The commissure of inferior colliculus, also called the commissure of inferior colliculi is a thin white matter structure consisting of myelinated axons of neurons and joining the paired inferior colliculi. It is evolutionarily one of the most ancient interhemispheric connections.
Anatomically, as the name suggests, the MLR is located in the mesencephalon (or midbrain), ventral to the inferior colliculus and near the cuneiform nucleus. [6] Although identifying the exact anatomical substrates of the MLR has been subject to considerable debate, the pedunculopontine nucleus (PPN), cuneiform nucleus, and midbrain ...
The colliculus as a whole is thought to help orient the head and eyes toward something seen and heard. [8] [34] [35] [36] The superior colliculus also receives auditory information from the inferior colliculus. This auditory information is integrated with the visual information already present to produce the ventriloquism effect.
This small artery supplies portions of the midbrain, [1] especially the superior colliculus, inferior colliculus, and tectum. Structure
IC = Inferior colliculus EE (Excitatory excitatory) type neurons are characterized by excitatory responses to monaural stimulations of both ears. This response may either be higher than the monaural response (EE– facilitation) Or lower (EE– occlusion)
The inferior colliculus is the principal midbrain nucleus of the auditory pathway and receives input from several peripheral brainstem nuclei, as well as inputs from the auditory cortex. Its inferior brachium (arm-like process) reaches to the medial geniculate nucleus of the diencephalon .
