  • Utilizes a microcomputer, a low-budget framegrabber, and a standard video camera for data acquisition.
  • The VIEWER software records animal position at up to 25 frames/s, determining location and orientation.
  • Processes movement velocity, direction, activity levels, and complex behavioral patterns online.

    • Main Results:

    • The system accurately records and analyzes a wide range of behavioral parameters in real-time.
    • Data can be presented in graphical or tabular formats and exported for further analysis.
    • Demonstrates an inexpensive, fast, and easy method for analyzing both simple and complex behaviors.

    Conclusions:

    • The VIEWER system offers a practical solution for behavioral analysis in diverse research settings.
    • It facilitates the study of animal responses to various stimuli and experimental conditions.
    • Provides a valuable tool for advancing research in pharmacology, toxicology, and behavioral neuroscience.
