Neural Pathways in Hearing and Restoration Techniques Quiz

Cochlear nerve fibers synapse in the thalamus and then transmit information to the auditory cortex

Cochlear nerve fibers synapse with interneurons in the brainstem, then information is transmitted to the thalamus and auditory cortex (correct)

Cochlear nerve fibers transmit information to the brainstem, then directly to the auditory cortex without involving the thalamus

Cochlear nerve fibers directly transmit information to the auditory cortex bypassing the brainstem and thalamus

Cochlear implants replace damaged components of the ear with artificial machinery to restore hearing

Cochlear implants stimulate the auditory cortex directly to compensate for damaged components of the ear

Cochlear implants directly amplify existing sounds in the ear canal

A speaker placed on the outside of the head picks up noises and transduces them into electrical impulses, which are sent to the vestibulocochlear nerve via electrodes, bypassing the damaged components of the ear (correct)

To directly stimulate the auditory cortex to compensate for reduced sensitivity

To pick up noises and transduce them into electrical impulses for transmission to the vestibulocochlear nerve

To replace damaged components of the ear with artificial machinery

To amplify existing sounds by using an amplifier placed in the auditory canal (correct)
