An electrophysiological study on coding of acoustic signals by auditory interneurons in cicada Cryptotympana atrata

Two types of auditory interneurons in cicada Cryptotympana atrata different in discharge patterns have been studied in terms of the response threshold-frequency relationships and the coding of intensity and temporal features of the acoustic signals.The results show that they can function as a simple sound intensity and timing coder and impulse marker,respectively.
