If a 1-nm deflection can produce a 0.2 mV voltage change in the hair cell, how many nm must the hair cell be deflected to move the resting membrane potential of -70 mV to a threshold of -50 mV?

Question

The voltage change needed is from -70 mV to -50 mV, which is a 20 mV change. Since 0.2 mV corresponds to a 1-nm deflection, a 20 mV change would require a 100-nm deflection (20 mV / 0.2 mV per nm = 100 nm).
