Researchers developed Wake-Forest Visual Experimentation (WaVE) software for precise control in psychophysical and neurophysiological studies. This free, customizable Matlab-based tool offers high-speed stimulus delivery and response monitoring.

Area of Science:

  • Neuroscience
  • Psychophysics
  • Computational Neuroscience

Background:

  • Psychophysical and neurophysiological research demands precise control over experimental devices for stimulus delivery and response monitoring.
  • Existing systems are often complex, proprietary, and have limited hardware compatibility.
  • There is a need for flexible, accessible software solutions for experimental control.

Purpose of the Study:

  • To introduce the Wake-Forest Visual Experimentation (WaVE) software, a novel solution for high-speed experimental control.
  • To demonstrate the software's capabilities in presenting visual stimuli and collecting data.
  • To highlight the software's flexibility and customization for diverse research needs.

Main Methods:

  • Developed a software solution entirely within the Matlab environment.

  • Utilized existing Matlab libraries and toolboxes for stimulus presentation, data collection, and inter-computer communication.
  • Validated performance through simulation, demonstrating sub-millisecond sampling rates and updating precision.

    • Main Results:

    • Achieved high-speed control of experimental and behavioral variables.
    • Demonstrated sub-millisecond sampling rate and updating precision on standard desktop PCs.
    • Confirmed the software's capability to present visual stimuli, collect data, and manage behavioral variables.

    Conclusions:

    • WaVE software provides a simple, flexible, and powerful alternative to costly, proprietary systems.
    • The software is freely available under the GNU public license, promoting accessibility in research.
    • Its portability allows customization for various operating systems and laboratory setups.
