What is an auditory pathway?
Auditory messages are conveyed to the brain via two types of pathway: the primary auditory pathway which exclusively carries messages from the cochlea, and the non-primary pathway (also called the reticular sensory pathway) which carries all types of sensory messages.
What are the 5 main major parts of the auditory pathway?
These nuclei include 1) cochlear nucleus, 2) superior olivary nuclei, 3) lateral lemniscus, 4) inferior colliculus, and 5) medial geniculate nuclei. [6] Auditory information ascending through the auditory pathways start at the auditory nerve.
What is the significance of the central auditory pathway?
This complex chain of nerve cells helps to process and relay auditory information, encoded in the form of nerve impulses, directly to the highest cerebral levels in the cortex of the brain.
What is the descending auditory pathway?
Descending auditory pathways originate from multiple levels of the auditory system and use a variety of neurotransmitters, including glutamate, GABA, glycine, acetylcholine, and dopamine. Descending pathways from the auditory cortex can evoke plasticity in subcortical centers.
What is unique about the way the auditory pathway travels to the brain quizlet?
Cochlear nerve; temporal lobe. What is unique about the way the auditory pathway travels to the brain? The auditory pathway is a unique sensory pathway because the ascending pathways cross in addition to sending signals to the same side of the brain. Nerve deafness occurs from damage to the nerve pathway.
What are auditory organs?
the sense organ that detects sound. In vertebrates it also provides information about the animal’s relationship to gravity, and its acceleration.
Do auditory nerves cross over?
Once they leave the cochlear nucleus, most of the axons of the cochlear nucleus cells cross over to the opposite side (contralateral side) of the brain (Figure 27 ). This means that most of the auditory information processed by each half of the brain comes from the ear on the other side of the head.
What are the four task of the auditory system?
What are the four tasks of the auditory system? – Pick up stimulus energy from the world around us. – Change that energy into a pattern of neural impulses. – Carry those impulses to the proper locations in the brain.
