Analysis of Circadian Photoresponses in Drosophila Using Locomotor Activity

Yong Zhang¹, Xueyan Pang¹, Zhenxing Liu¹

¹Department of Biology, University of Nevada Reno

Drosophila locomotor activity is a robust and quantitative measurement of circadian photo-responses. We describe protocols for designing behavior experiments for circadian photo-responses and analyzing the data. Studying the circadian photo-responses is important for dissecting the neuronal and molecular mechanisms of light entrainment.

¹Institute of Nuclear and New Energy Technology, Key Laboratory of Advanced Reactor Engineering and Safety of Ministry of Education, Collaborative Innovation Center for Advanced Nuclear Energy Technology, Tsinghua University, ²Institute of Nuclear and New Energy Technology, Beijing Key Laboratory of Fine Ceramics, Tsinghua University

Key procedures to optimize the sealing process and achieve real-time monitoring of the metal-to-glass seal (MTGS) structure are described in detail. The embedded fiber Bragg grating (FBG) sensor is designed to achieve online monitoring of temperature and high-level residual stress in the MTGS with simultaneous environmental pressure monitoring.
