| Outline of Final Research Achievements |
Visual information processing in motion detection is an important topic of neuroscience. However, the details of motion detection circuits remain elusive. In this study, we used the fly visual center as a model to elucidate the structure and function of motion detection circuits.
As a first step, I constructed an insect area, in which various visual stimuli can be presented to a fly and its response can be quantified using an infrared sensor. Using this system, I examined the roles of potential motion detection neurons such as Mi1, Lawf1 and Lawf2. As a result, I found that Mi1 plays a central role in motion detection and that Lawf1 and Lawf2 act co-operatively.
