Area of Science:

  • Ethology
  • Chronobiology
  • Animal Behavior

Background:

  • Quantitative behavior studies often focus on short timescales, limiting understanding of longer temporal structures.
  • Investigating long-timescale animal behavior requires extended, continuous recording and advanced analysis techniques.

Conclusions:

  • Extended behavioral recording reveals complex temporal structures, including circadian rhythms and age-related changes.
  • Deep learning-based pose estimation is effective for generating large-scale behavioral datasets.
  • This study provides insights into the full temporal dynamics of animal behavior from daily cycles to lifespan changes.
