Piezo-mediated mechanosensation contributes to stabilizing copulation posture and reproductive success in Drosophila males
iScience · Volume 26, Issue 5 · 2023
DOI: 10.1016/j.isci.2023.106617
We discovered that Piezo, a mechanosensitive ion channel, is involved in postural control during copulation in male fruit flies. We further showed that destabilizing the male copulation posture by blocking Piezo can reduce reproductive performance. These findings indicate that males actively maintain their posture during copulation via mechanosensation, and that doing so contributes to reproductive success. This work is expected to help reveal the full picture of the molecular and neural mechanisms that control copulation behavior in animals.
Protocol to investigate the neural basis for copulation posture of Drosophila using a closed-loop real-time optogenetic system

We report a new experimental method for optogenetically silencing neurons exclusively during copulation in Drosophila. In this approach, copulation is detected in real time using DeepLabCut-Live!, a machine learning-based tool for real-time pose estimation in animals, and the detection output is used to control laser illumination.

Event-triggered feedback system using YOLO for optogenetic manipulation of neural activity
IEEE. 2023 IEEE PerCom Workshops · 2023
DOI: 10.1109/PerComWorkshops56833.2023.10150245
We showed that YOLO (YOLOv5), a deep learning-based object detection algorithm, can recognize copulation behavior in fruit flies. By performing this recognition in real time, we further proposed a system that can intervene in behavior using the behavior itself as a trigger.
