In class yesterday a distinct image popped into my head while we were discussing auditory and visual signals/ action potentials: A telephone operator controlling a switchboard. If the action potential that propogates when you hear something is the same as when you hear something, does that really means that we potentially could move the extension from the auditory to the visual "box"? And are our Nervous Systems really like switch boards that propogate input manually because the signals aren't created uniquely for specific functions? I really don't like the battery analogy and am interested to see where we go with it.
