It works a bit like a FET or valve.
Cray stopped research ages ago, but they principle has been applied in making standard voltage cells, SQID's and single electron transistors.
The frequency of the "gate" current vs the voltage across the junction is very linear.
Building an amplifier where the gain is controlled by gate frequency rather than voltage or current sounds really tricky.
Try clove oil or cinnamon stick, both are good topical anesthetics.
