Dr. Poulet at the Federal Polytechnical School of Lausanne in Switzerland, said that crickets had a very simple nervous system and made very loud noises. Several years ago, Dr. Poulet and Dr. Hedwig discovered that at the precise instant a cricket moved its forewing muscles to create a chirp, its auditory neurons became inhibited, or desensitized, presumably by some chemical neurotransmitter. Dr. Poulet used a trial and error approach to discovering the signal pathway, recording electrical discharges in neurons while a cricket was making chirping motions. James F. A. Poulet, who is now at the Federal Polytechnical School of Lausanne in Switzerland, said that Crickets have a very simple nervous system and make very loud noises. Several years ago, Dr. Poulet and Dr. Hedwig discovered that at the precise instant a cricket moved its forewing muscles to create a chirp, its auditory neurons became inhibited, or desensitized, presumably by some chemical neurotransmitter. He also found that there were no corollary signals produced when the cricket was flying -- which it does by moving its wings, but in a different pattern than when chirping.
