DeepLabCut (DLC) with Simple Behavioral Analysis (SimBA) accurately quantifies mouse grooming duration, but both DLC/SimBA and HomeCageScan (HCS) struggle with accurately measuring grooming bout counts compared to manual scoring.

Area of Science:

  • Behavioral Neuroscience
  • Machine Learning Applications
  • Animal Behavior Analysis

Background:

  • Automated behavioral analysis tools are increasingly important in neuroscience.
  • Standardized quantification of animal behavior is crucial.
  • Machine learning advances drive the development of these tools.

Purpose of the Study:

  • Compare automated tools (DeepLabCut/SimBA, HomeCageScan) against manual scoring for mouse grooming.
  • Evaluate accuracy in measuring grooming duration and bout counts.
  • Assess tool performance under different behavioral conditions.

Main Methods:

  • Recorded mouse grooming behavior at baseline and after stress treatments (water spray, restraint).
  • Analyzed videos using DeepLabCut/SimBA, HomeCageScan, and manual scoring.

  • Quantified total grooming bouts and total grooming duration.

    • Main Results:

    • Both treatments increased grooming duration and bout counts.
    • HomeCageScan overestimated grooming duration compared to manual scoring.
    • DeepLabCut/SimBA duration measurements closely matched manual scoring.
    • Both automated methods showed significant differences in grooming bout counts versus manual scoring.

    Conclusions:

    • DeepLabCut/SimBA offers a high-throughput, accurate method for quantifying mouse grooming duration.
    • Neither DeepLabCut/SimBA nor HomeCageScan reliably measured grooming bout counts compared to manual scoring.
