Question 1

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-The best frequency of a neuron

Accepted Answer

The best frequency of a neuron is referred to as its characteristic frequency, which is the frequency at which a neuron is most responsive or has the lowest threshold for activation.

Question 2

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-The area benefit, in decibels

Accepted Answer

The area benefit, in decibels, refers to the amplification provided by the difference in area between the tympanic membrane and the oval window, which is approximately 25 dB.

Question 3

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-The change in VIII nerve firing rate when the crossed olivocochlear and uncrossed olivocochlear bundles are stimulated

Accepted Answer

Stimulation of the olivocochlear bundles typically results in a decrease in the firing rate of the auditory nerve (VIII nerve).

Question 4

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-The first level of brainstem processing of the auditory signal

Accepted Answer

The cochlear nucleus is the first level of brainstem processing of the auditory signal, where initial processing and integration of auditory information occur.

Question 5

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-Responses that have a slowly increasing firing-rate response to a stimulus during depolarization

Accepted Answer

Build-up responses are characterized by a slowly increasing firing-rate response to a stimulus during depolarization.

Question 6

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-The level of threshold seen in low spontaneous rate neurons

Accepted Answer

Low spontaneous rate neurons typically have a high threshold level, meaning they require a stronger stimulus to activate compared to high spontaneous rate neurons.

Question 7

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-Response that has delayed onset relative to other neurons

Accepted Answer

Pausers are neurons that have a delayed onset relative to other neurons.

Question 8

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-Structure that, in combination with the oval window, provides an area benefit

Accepted Answer

The tympanic membrane, in combination with the oval window, provides an area benefit that contributes to the impedance matching function of the middle ear.

Question 9

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-The bone upon which the tensor tympani muscle exerts a restraining force

Accepted Answer

The tensor tympani muscle exerts a restraining force on the malleus, which is one of the small bones in the middle ear.

Question 10

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-Increase of signal intensity causes this in the rate of firing of auditory nerve neurons

Accepted Answer

An increase in signal intensity typically causes an increase in the rate of firing of auditory nerve neurons.

Question 11

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-Structure that, in combination with the incus, provides the lever benefit of the middle ear system

Accepted Answer

The answer of Match each term to the correct descriptor....

Question 12

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-A tuning curve that has this characteristic will reveal greater specificity to a stimulus

Accepted Answer

Sharpness refers to the tuning curve's specificity to a stimulus. A sharper tuning curve indicates greater specificity.

Question 13

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-End of the cochlea at which low-frequency sounds are processed

Accepted Answer

Low-frequency sounds are processed at the apical end of the cochlea.

Question 14

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-Cochlear potential that arises directly from stimulation of a large number of hair cells simultaneously, eliciting nearly simultaneous individual action potentials in the VIII nerve

Accepted Answer

The whole-nerve action potential is the cochlear potential that results from the simultaneous stimulation of many hair cells, leading to nearly simultaneous action potentials in the auditory nerve (VIII nerve).

Question 15

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-The lever benefit, in decibels

Accepted Answer

The lever benefit in the middle ear, which is the gain provided by the lever action of the ossicles, is approximately 2 dB.

Question 16

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-End of the cochlea at which high-frequency sounds are processed

Accepted Answer

High-frequency sounds are processed at the basal end of the cochlea.

Question 17

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-The bone upon which the stapedius muscle exerts a restraining force

Accepted Answer

The stapedius muscle exerts a restraining force on the stapes bone in the middle ear.

Question 18

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-Response that is unrelated to stimulus frequency but reveals a chopped, periodic temporal pattern as long as the stimulus remains present

Accepted Answer

Chopper responses are characterized by a chopped, periodic temporal pattern that continues as long as the stimulus is present, unrelated to the stimulus frequency.

Question 19

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-Response in which there is an initial response to the stimulus, followed by neural silence

Accepted Answer

Onset responses are characterized by an initial response to a stimulus followed by a period of neural silence.

Question 20

Match each term to the correct descriptor. Terms may be used more than once or not at all.
-Defined as resistance to the flow of energy

Accepted Answer

Impedance is defined as resistance to the flow of energy.
