Area of Science:

  • Neuroscience
  • Behavioral Science
  • Bioengineering

Background:

  • Accurate rodent behavior tracking is crucial for understanding neurological disorders and social interactions.
  • Existing systems can be costly, complex, and lack scalability for multi-animal studies.

Purpose of the Study:

  • To introduce PyMouseTracks (PMT), a cost-effective, scalable, and customizable system for rodent tracking and behavior analysis.
  • To validate the system's accuracy and explore its application in assessing sociability and motor deficits.

Main Methods:

  • Developed a Raspberry Pi-based system integrating computer vision and RFID for real-time data acquisition.
  • Implemented offline analysis tools for processing tracking data from multiple mice.
  • Validated system accuracy against manual tracking and interfaced with DeepLabCut and Traja for advanced analysis.

Main Results:

  • PMT achieved >85% accuracy in tracking up to six mice for extended periods.
  • Identified diurnal activity patterns and novel similarities in travel trajectories between non-cagemate mice, suggesting a measure of sociability.
  • Successfully resolved motor deficits in stroke models when combined with Traja analysis.

Conclusions:

  • PMT offers an affordable, open-source, and customizable solution for rodent behavior research.
  • The system provides valuable insights into animal sociability and motor function.
  • PMT facilitates advanced behavioral phenotyping and analysis in neuroscience research.
