L3 Auditory Interneuron Responses To Dual-Frequency Calling Songs In Female Crickets (Acheta Domesticus), Jeong Bin Lee
Honors Theses
Female crickets exhibit positive phonotaxis in response to calling songs with specific carrier frequencies (4-5 kHz), syllable periods (SP; 50-70ms), and other parameters. Among a number of ascending prothoracic auditory neurons identified, only L3 has been proposed to be involved in SP selective phonotaxis. L3 responds with selective decrement to 5 kHz stimulus with attractive SPs. Furthermore, L3 is highly tuned to 16 kHz auditory stimulus, which has been correlated with aversive phonotactic behaviors. L3’s cellular responses to simultaneous 16 kHz and 5 kHz stimuli were examined through extracellular recording, thereby further establishing the connection between L3’s selective decrement and …
