What are the two main types of VIII nerve neurons?
The two main types of VIII nerve neurons are:
? High-threshold neurons require a higher intensity and encompass the higher end of our auditory system of signal intensity. Thus high-threshold fibers may process higher levels of sound.
? Low-threshold neurons may process near-threshold sounds. Low threshold fibers respond at very low signal levels and display random firing even when no stimulus is present.
