part 3 (study guide)

Question 1

What makes up the peripheral auditory system

Answer 1

outer, middle, and inner ear

Question 2

What makes up the central auditory system

Answer 2

cochlear nuclei, superior olivary nuclei, lateral lemniscus, inferior colliculus, medial geniculate nuclei, and auditory cortex

Question 3

What is a characteristic delay

Answer 3

spike count reaches a maximum for a certain disparity between the time of arrival of sound at the two ears (interaural time delay is important for this, not frequency)

Question 4

what does a discharge rate show up on

Answer 4

Neural excitation pattern y-axis

discharge rate = the activity rate of a group of neurons resulting in an action potential

Question 5

What do the different spontaneous discharge rates mean (low medium and high)

Question 6

Neural spectrum specifics

Answer 6

for a neural spectrum, we want to look at how a whole bunch of neurons sample sound

how does the nerve represent that tone

aligns with the BM displacement graph because the neural excitation pattern shows the pattern of displacement of the neurons
