    Purpose of the Study:

    • To describe a novel, inexpensive technique for visual system stimulation.
    • To enable precise, individual stimulation of color channels.
    • To facilitate advanced psycho- and neurophysiological studies.

    Main Methods:

    • Development of a compact instrument combining continuous interference filters and light fibers.
    • Utilizing narrow-band light for stimulation in mosaic or homogeneous compositions.
    • Ensuring separate control over all stimulation parameters.

    Main Results:

    • The technique provides adequate stimulation of the visual system.
    • Individual color channels can be stimulated independently.
    • Parameters of light stimulation are precisely controllable.

    Conclusions:

    • This method offers a simple and affordable approach to visual stimulation.
    • The instrument allows for detailed studies in psycho- and neurophysiology.
    • The precise control over stimulation parameters enhances research capabilities.
