What is the inferior colliculus role in auditory processing?
What is the inferior colliculus role in auditory processing?
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.
Is the auditory reflex center in the inferior colliculus?
The inferior colliculus (IC) (Latin for lower hill) is the principal midbrain nucleus of the auditory pathway and receives input from several peripheral brainstem nuclei in the auditory pathway, as well as inputs from the auditory cortex.
Where does the inferior colliculus project auditory impulses to?
The inferior colliculus receives both crossed and uncrossed auditory fibres and projects upon the medial geniculate body, the auditory relay nucleus of the thalamus.
What is the Brachium of the inferior colliculus?
The brachium of the inferior colliculus is a pathway carrying fibers between the inferior colliculus and the ipsilateral medial geniculate body, which is located in the metathalamus, the caudal subpial portion of the thalamus.
What conveys auditory Fibres to the inferior colliculus?
The second major relay in the brain stem is in the superior olivary complex: the majority of the auditory fibres synapse there having already crossed the midline. Leaving this relay, a third neuron carries the mesage up to the level of the inferior colliculus (mesencephalus ).
What conveys auditory fibres to the inferior colliculus?
What is the auditory pathway for hearing?
Brain cells, known as sensory neurons, transmit the sound information to various areas of the brain, including the thalamus, temporal lobe, and auditory cortex, the National Institutes of Health explains. These are known as the auditory pathways.
Where does the auditory pathway Decussate?
These fibers synapse in the dorsal cochlear nucleus, and may function as a general warning (as when you might jump from a loud sound). These fibers decussate and ascend in the lateral lemniscus to the inferior colliculus. Ascending pathway for most auditory afferents.
What is inferior Brachium?
The Brachium of inferior colliculus (or inferior brachium) carries auditory afferent fibers from the inferior colliculus of the mesencephalon to the medial geniculate nucleus.
