What is superior and inferior Brachium?
The superior brachium establishes the connection between the two superior colliculi, the lateral geniculate body and the optic tract. The inferior brachium links the two inferior colliculi with the medial geniculate body, which in turn is connected to the auditory cortex.
What is a Brachium of superior colliculus?
The brachium of superior colliculus (or superior brachium) is a branch that extends laterally from the superior colliculus, and, passing between the pulvinar and medial geniculate body, is partly continued into an eminence called the lateral geniculate body, and partly into the optic tract.
What is Quadrigeminal Brachium?
a band of fibers from the optic tract that bypasses the lateral geniculate body to terminate in the superior colliculus and pretectal region.
What is the inferior colliculus role in auditory processing?
2.45. 7 Inferior Colliculus. The inferior colliculus (IC) is a major site of convergence in the auditory system. The IC receives multiple parallel streams of ascending and descending information and has its main auditory output to the auditory thalamus.
What is a superior colliculus in anatomy?
The superior colliculus is a paired structure in the rostral midbrain that is involved in incorporating environmental stimuli and coordinating gaze shifts involving both eye and head movements.
What does the pulvinar nucleus do?
The pulvinar nucleus of the thalamus, for example, is involved in filtering or suppressing irrelevant stimuli in a cluttered display. However, the cortical region that plays the most significant role in the control of spatial attention is the posterior parietal region.
What are the inferior Colliculi?
The inferior colliculus (IC) is a major site of convergence in the auditory system. The IC receives multiple parallel streams of ascending and descending information and has its main auditory output to the auditory thalamus.
What is inferior colliculus and superior colliculus?
The inferior colliculi of the midbrain are located just below the visual processing centers known as the superior colliculi. The inferior colliculus is the first place where vertically orienting data from the fusiform cells in the dorsal cochlear nucleus can finally synapse with horizontally orienting data.
