DOI: 10.3791/54359-v
What you'll learn
  • ✓ Set up hardware and record C. elegans swimming behavior in liquid medium
  • ✓ Process video files and extract behavioral measurements using CeleST software
  • ✓ Analyze swimming kinematics to detect age-related behavioral changes
  • ✓ Implement open-source analysis pipeline with minimal equipment investment
Protocol

An efficient and simple methodology for computer-based analysis of nematode swimming behavior in liquid is described. The method requires little to no investment for C. elegans laboratories. The hardware used is standard, and the computer software for the behavioral analysis (CeleST) is an open source one.
