    Area of Science:

    • Neuroscience
    • Biomedical Engineering
    • Sensory Physiology

    Background:

    • Investigating the neural processing of complex cutaneous stimuli, like moving textures, requires advanced and adaptable stimulation tools.
    • Existing devices may lack the versatility needed for detailed studies on tactile sensation and neural pathways.

    Purpose of the Study:

    • To describe the construction and application of a novel, cost-effective instrument for generating versatile moving cutaneous stimuli.
    • To provide researchers with a flexible tool for exploring the neural basis of tactile perception.

    Main Methods:

    • The instrument's electronic component features a variable rate integrator, integrated with a Grass P5 plug-in for precise control.
    • A P5 driver amplifier powers a pen motor mechanism, generating controlled tactile movements.
    • The system allows for selection of stimulus velocity, excursion, and direction.

    Main Results:

    • The constructed instrument successfully generates a range of moving cutaneous stimuli with adjustable parameters.
    • The device is relatively inexpensive and utilizes commonly available neurophysiological laboratory equipment.
    • The system demonstrates reliable operation for delivering controlled tactile input.

    Conclusions:

    • This versatile and affordable instrument facilitates advanced research into the neural processing of moving cutaneous stimuli.
    • The developed device offers a practical solution for laboratories studying tactile sensory mechanisms and neural responses.
