Imagine that a sound wave has traveled through the ear and caused a mechanical vibration within the fluid of the inner ear. This vibration has successfully triggered the sensory receptor cells to generate a neural impulse. What is the direct and immediate next step in the pathway for this signal to be processed as sound?

A person is listening to an orchestra and can simultaneously distinguish the high-pitched notes of a flute from the low-pitched notes of a cello. Which structural feature of the nerve that transmits sound information from the inner ear is most critical for this ability to perceive multiple, distinct pitches at once?
