Plasticity In Selective Phonotaxis And Neuronal Responses Of Acheta Domesticus, Benjamin Alejandro Navia Jun 2005

Plasticity In Selective Phonotaxis And Neuronal Responses Of Acheta Domesticus, Benjamin Alejandro Navia

Loma Linda University Electronic Theses, Dissertations & Projects

Plasticity of phonotaxis in Acheta domesticus was evaluated in 207 young (5-7 days) and 328 old (28 days) female crickets. Of those that responded (508), their phonotaxis was grouped into selective (80% of young and 34% of old) and unselective (66% of old and 20% of young) on the basis of their responses to syllable period (SP). Two additional subcategories were also found. Some females were selective to the longer syllable periods (18% young, 20% old) while others were selective to the shorter syllable periods (7% young and 12% old). The L3 prothoracic auditory interneuron exhibits a decrementing response to …
