L3 Auditory Interneuron Responses To Dual-Frequency Calling Songs In Female Crickets (Acheta Domesticus), Jeong Bin Lee
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 …

Selective Processing By The L3 Auditory Interneuron In Acheta Domesticus : Juvenile Hormone Iii And Protein Kinase C, Ashley Ranae Lynch
Master's Theses
Juvenile Hormone III (JHIII) is a prolific and essential hormone in insects, controlling many aspects of insect physiology such as egg development, nymphal and larval maturation, diapause and metamorphosis. In female crickets, Acheta domesticus, JHIII increases selectivity in phonotactic behavior, narrowing phonotactic choices for Syllable Periods (SPs) of the Calling Songs (CSs) that most closely resemble the natural call of the male. JHIII has been suggested to work through a pathway that activates the protein kinase C (PKC) molecule. Chelerythrine Chloride (CC) is a potent inhibitor of PKC action. This study analyzes the responses of the L3 auditory interneuron, which …
