Which of the following is true of rate coding along the basilar membrane?
A) Rate coding occurs for frequencies greater than 500 Hz.
B) The basal end of the basilar membrane shows the greatest movement to a frequency of less than 200 Hz.
C) Lower frequencies are coded by rate of firing that is cued to the movement of the apical end of the basilar membrane.
D) Cochlear implants can be used to signal frequencies up to 20,000 Hz.
E) Rate coding is due to volleys of neurons that fire in sequence.
Question 2

C) the contractile capacity of inner hair cells.
D) the contractile capacity of outer hair cells.
E) longitudinal tension of the basilar membrane.
