Directional hearing of a grasshopper in the field.


An electrophysiological method for making long-term recordings from the tympanal nerve was developed in Chorthippus biguttulus (Gomphocerinae) to gain insight into the ecophysiological constraints of sound localization in acridid grasshoppers. Using this 'biological microphone', the directional dependence of auditory nerve activity was monitored both in the… (More)
