The electrochemical gradient of hair cells is directly related to the amount of calcium present in these cells. This is because these cells have a very high calcium concentration, causing constant leakage. These leaks are the main responsible for the release of the neutrotransmitters that will participate in the synapses.
In addition, this amount of calcium present in the hair cells is what makes these cells have an incredible speed in responding to mechanical stimuli, which makes all the difference within a biological system.
