Correct Answer
Afferent fibers
Question 8
The process during the action potential when sodium is rushing into the cell causing
the interior to become more positive.
Correct Answer
Depolarization
Question 9
dorsal cochlear nucleus
Correct Answer

,Question 12
auditory nerve spikes only occur for one direction of the BM vibration
Correct Answer
Half-wave rectification
Question 13
cues sound location that requires just one ear
Correct Answer
monaural cues
Question 14
high frequencies (>5000 Hz)
Correct Answer
Poor synchrony happens at...
Question 15
cues sound location that requires both ears
Correct Answer
binaural cues
Question 16
a delay line and coincidence detector model for processing. The ladder like delay lines
transmit inputs from both ears to each coincidence detector. Due to the length
difference between delay lines, different neurons will fire with different ITDs
Correct Answer
The Jefferess Model

, Question 17
the cochlea encodes different frequencies at different locations along the basilar
membrane
Correct Answer
Place code
Question 18
A specialized ion channel that opens or closes in response to changes in membrane
potential
Correct Answer
Voltage-gated Ion Channels
Question 19
The increase in spike rate for any auditory nerve only happens over a 30-50 dB
dynamic range, above which the neural spike rate saturates
Correct Answer
What are the limits that rate code has?
Question 20
MSO cells fire maximally when the left and right ear inputs arrive the cell body at the
same time
Correct Answer
Coincidence detection at MSO
Question 21
Post-Stimulus Time(PST) Histogram, Inter-Spike Interval (ISI) Histogram, and Phase-
Locked PST Histogram
Correct Answer
What are the graphs are used to show temporal processing?
