2. Which of the following statements is FALSE:
A. INCORRECT. During transduction of auditory stimuli, ion
channels located at the tips of the stereocilia are mechanically opened,
resulting in depolarization of the inner hair cell.
B. INCORRECT. The tonotopic representation of frequency is
passed from the lateral geniculate nucleus to the primary auditory cortex
C. INCORRECT. The main function of the middle ear is to
match the impedance of air to the impedance of the fluid in the cochlea.
D. CORRECT.
Basilar membrane vibration is frequency dependent: High frequency sounds produce larger
deflections in the base of the cochlea, and low frequency sounds in the apex.
