Question 1

The planum temporale is:

Accepted Answer

The answer of The planum temporale is:
...

Question 2

Barn owls' ears are at different heights on the left and right sides of their head.This unique feature helps them better locate sounds that are:

Accepted Answer

The answer of Barn owls' ears are at different heights...

Question 3

Damage to the _____ can cause problems with both language and taste perception.

Accepted Answer

The insula is a part of the brain that is involved in taste perception as well as in language processing. Damage to the insula can therefore result in problems with both taste perception and language function. The other options (left planum temporale, left Wernicke's area, and right parietal cortex) are also involved in language processing, but not in taste perception.

Question 4

The axons of _____ form the auditory nerve.

Accepted Answer

The answer of The axons of _____ form the auditory...

Question 5

_____ has a special role in processing music.

Accepted Answer

The answer of _____ has a special role in processing...

Question 6

Gerald is walking through the forest at night,and he hears what sounds like an animal walking somewhere to his left.Gerald localized the source of this sound using _____,which relies on neurons in the _____.

Accepted Answer

The localization of sound based on differences in arrival time between the two ears is known as interaural time difference. This is processed by neurons in the lateral superior olive. Loudness differences between the two ears are processed by neurons in the medial superior olive, but this is not the relevant mechanism for sound localization in this scenario.

Question 7

The left planum temporale is generally larger in:

Accepted Answer

Research shows that the left planum temporale is typically larger in right-handed individuals, who also tend to have language functions primarily localized to the left hemisphere of the brain.

Question 8

A study by Thaler and colleagues examined the brain regions involved in human echolocation by blind individuals.Their study found that echolocation in blind individuals seemed to rely on activation in:

Accepted Answer

The study by Thaler and colleagues found that blind individuals using echolocation showed activation in the visual cortex, suggesting that this area of the brain is repurposed for processing echolocation sounds.

Question 9

Rachael hears what sounds like a car alarm sounding off.In order for her to localize this high frequency continuous sound her auditory system will take advantage of:

Accepted Answer

The answer of Rachael hears what sounds like a car...

Question 10

Inputs from the _____ are sent to primary auditory cortex (A1).

Accepted Answer

Inputs from the ventral medial geniculate nucleus are sent to primary auditory cortex (A1).

Question 11

Damage to the left auditory cortex would lead to:

Accepted Answer

The answer of Damage to the left auditory cortex would...

Question 12

_____ is (are)often used to measure the functionality of the inner ear in newborn infants.

Accepted Answer

Otoacoustic emissions (OAEs) are sounds that are generated by the inner ear in response to external sounds. These emissions can be detected with a small microphone placed in the ear canal, and are often used to test the functionality of the inner ear in newborn infants. The presence or absence of OAEs can indicate whether there is a hearing problem, and can help determine the appropriate course of treatment or intervention. Frequency analysis, Fourier analysis, and auditory evoked potentials (AEPs) are other methods that can be used to evaluate hearing function, but OAEs are particularly useful for testing newborns because they are non-invasive and do not require the cooperation of the patient.

Question 13

Research on the tuning curves of individual inner hair cells indicates that:

Accepted Answer

Research has shown that each individual inner hair cell responds maximally to a particular frequency, which is known as its characteristic frequency. However, they also respond somewhat to nearby frequencies, resulting in a tuning curve that shows a range of frequencies to which the hair cell responds with varying degrees of sensitivity.

Question 14

Which of the following sequences is the correct auditory route to the cortex?

Accepted Answer

The answer of Which of the following sequences is the...

Question 15

The recognition of objects by sound is accomplished by the:

Accepted Answer

The ventral auditory pathway processes sound information for object recognition and identification, while the dorsal auditory pathway processes sound information for spatial localization and movement processing. The anterior and lateral auditory pathways are not involved in these specific functions.

Question 16

Bipolar cells receive input from:

Accepted Answer

The answer of Bipolar cells receive input from:
...

Question 17

Increases in loudness are coded by:

Accepted Answer

Increases in loudness are coded by an increased rate of firing in bipolar cells. As the sound waves become louder, the hair cells in the inner ear are stimulated more strongly, which leads to higher firing rates in the bipolar cells that transmit the information to the brain. This increased firing rate is interpreted as an increase in loudness.

Question 18

The thalamic relay nucleus for the auditory system is the:

Accepted Answer

The thalamic relay nucleus for the auditory system is the medial geniculate nucleus (MGN). The pulvinar nucleus is involved in visual and somatosensory processing, and the lateral geniculate nucleus is the thalamic relay nucleus for the visual system. The ventrolateral nucleus is involved in motor and somatosensory processing.

Question 19

The human A1 auditory area is found in:

Accepted Answer

The human A1 auditory area is found in Heschl's gyrus, a region of the temporal lobe that is primarily responsible for processing sound information. The other choices, the planum temporale, Wernicke's area, and Broca's area, are also located in the temporal lobe but are associated with language processing, not auditory processing.

Question 20

Studies with humans have shown that if two sounds presented through earphones are separated by as little as _____ microseconds,the sound will be perceived as being on the side of the leading ear.

Accepted Answer

Studies with humans have shown that if two sounds presented through earphones are separated by as little as 10 microseconds, the sound will be perceived as being on the side of the leading ear.
