It is definitely more than just a variable resistor - there are time
dependent effects. It appears (though is far from proven) that the
hair cells are electrically tuned to approximately their
characteristic frequency. This tuning depends on a feed back loop
between voltage-gated Ca++ channels (open with depolarization) and
Ca++-gated K+ channels (open with increased Ca++ and hyperpolarize
