Traveling Wave
This term describes how different frequencies are represented at different locations along the cochlea (basilar membrane).
What is tonotopic organization?
This protein allows OHCs to change length and amplify sound vibrations.
What is prestin?
This positive resting potential in the scala media drives potassium into hair cells.
What is the endocochlear potential?
This cranial nerve carries auditory and vestibular information from the cochlea to the brain.
What is vestibulocochlear nerve (CN VIII)?
The base of the cochlea responds to high frequencies; the apex of the cochlea responds to low frequencies.
What is base; What is apex?
This period occurs after depolarization when the hair cell cannot respond to another stimulus.
What is refractory period?
This fluid contains sodium and contributes to the negative endocohlear potential.
What is perilymph?
12
What is the number of cranial nerves that carry information to and from the CNS and PNS.
This theory explains how how frequency is represented by the location of displacement along the basilar membrane.
What is place theory?
Damage to the OHCs would cause this type of hearing loss.
What is sensorineural hearing loss?
Theory that states that the firing limit of a single neuron can be overcome with a sum of multiple neurons.
What is volley theory?
Patients will report having difficulty hearing noise despite having a normal audiogram.
What is cochler synaptopathy?
