    Area of Science:

    • Neuroscience
    • Ophthalmology
    • Biomedical Engineering

    Background:

    • Optokinetic nystagmus (OKN) involves rhythmic eye movements.
    • Maximal OKN is elicited by a fully encompassing visual field stimulus.
    • Traditional optokinetic drums are large, heavy, and require powerful motors.

    Purpose of the Study:

    • To describe the construction of a novel optokinetic drum.
    • To design a drum that minimizes moment of inertia.
    • To create a cost-effective optokinetic stimulus device.

    Main Methods:

    • Detailed construction blueprints and material specifications for a lightweight optokinetic drum.
    • Design focused on reducing the moment of inertia for rapid acceleration.
    • Utilized cost-efficient materials and assembly techniques.

    Main Results:

    • Successfully constructed an optokinetic drum with significantly reduced moment of inertia.
    • The novel design allows for rapid acceleration and deceleration.
    • The construction costs were substantially lower than conventional drums.

    Conclusions:

    • The developed optokinetic drum is suitable for eliciting OKN.
    • This design offers a more accessible and efficient tool for visual-motor research.
    • Facilitates advanced studies on eye movement control and visual perception.
