Neural function is more a chemical reaction than it is an electrical transmission.
The synapse, then, is the "guts" of the perceptual processes (to be discussed next), which involve the control and structuring of these neural impulse wave patterns created through transduction.
The importance and mode of operation of the synapse underscores the role of chemicals in the thought processes; and in my mind the need for good nutrition to keep these processes functioning correctly is worth consideration.
Although the hair cells can generate electrical potentials that mirror in number the frequency of a sound wave, the connecting nerve cells are relatively limited.
A nerve cell can fire (replenish its nutrients to create and carry a potential) no more than 1000 per second and then no more than for a second.
If many cells are involved in such a massive operation, they simply "poop out" and we experience a Temporary Threshold Shift.
