What is the meaning of noise in biological systems?
Biological resistance can be conceptually translated as “noise.” The less the biological resistance, the less the “noise.” Nano amperes (one over a billion of an ampere) cause minimal resistance because of their miniscule nature. By the same reasoning, micro-current (one over one million of an ampere) will cause greater resistance and therefore more noise and miliamp (one over one thousand of an ampere) will cause even greater resistance, and therefore a considerable increase of noise.
