Outline of Final Research Achievements |
To start a high-through put analysis of the acoustic behavior of fruit flies, we developed an automatic system'ChaIN', to quantify the typical acoustic behavior of flies using machine-vision. By using this ChaIN software, we analyzed the acoustic behavior in response to sound of different patterns and found that the flies changed their response behavior immediately after the sound shift.This behavioral change was observed even in a memory mutant strain that lacks the rutabaga adenylyl cyclase gene, showing that the neural mechanism that discriminates sound patterns is independent of this gene. This project established a novel method to explore the neural mechanism how the brain discriminates different temporal pattern of acoustic stimuli.
