Auditory evoked responses recorded at the brain of the cricket, Acheta domesticus

Response specificity of the brain in cricket hearing has not been primarily studied. In this study the cricket was fixed and placed in a calibrated sound field. Pure tones were presented between 4kHz and 40kHz with a Blackman envelope. The stimuli were 2 msec in duration. The response epoch was averaged over 20 msec and the electrophysiologic responses were averaged to minimize biologic noise and strengthen the obtained response. Both the morphology of the response and audibility curve of cricket was obtained.
