And then there was the time a pair of Princeton researchers turned a cat into a living telephone – FOR SCIENCE! To the pair’s astonishment, the signals detected from the cat’s auditory nerve were remarkably clear, almost as if they had been produced by a mechanical telephone transmitter. In every case transmission abruptly stopped, confirming that the signals were indeed coming from the auditory nerve. This was based on an observation made during the telephone cat experiments that the frequency of many perceivable sounds exceeds the maximum known firing frequency of nerve cells. Shortly after the publication of their 1930 paper on the cat telephone experiments, it was discovered that several of their major conclusions were in fact mistaken.
