| Research Abstract |
Each animal moves in a certain speed. Though this observation seems obvious, it is still almost unclear how neural circuits generate speed of animal locomotion. In this study, using a motor circuit of Drosophila larvae as a model system, which is amenable to detailed analyses of neuronal networks, we examined the mechanisms of speed control of the larval locomotion. We found that a subset of interneurons, we named per-IN, regulate speed of locomotion by shortening the duration of motor neuronal activities.
