    This study introduces two microcomputer programs for digitizing neurophysiological signals. These programs offer flexible timing and high sampling rates for efficient analog-to-digital conversion.

    Area of Science:

    • Neuroscience
    • Biomedical Engineering
    • Computer Science

    Background:

    • Accurate digitization of neurophysiological signals is crucial for research.
    • Existing analog-to-digital conversion methods may lack flexibility or speed.
    • Microcomputer-based solutions offer potential for accessible data acquisition.

    Purpose of the Study:

    • To present two novel microcomputer programs for analog-to-digital (A-to-D) conversion of neurophysiological data.
    • To provide flexible control over signal timing and sampling parameters.
    • To enable efficient and accessible data acquisition for neuroscience research.

    Main Methods:

    • Implementation of two microcomputer programs: TIMET for pulse train timing and ADC8 for A-to-D conversion.
    • TIMET offers continuous or triggered pulse trains with adjustable onset delay.

  • ADC8 supports high sampling rates (up to 30 kHz single channel, 9 kHz multi-channel) with minimal inter-channel lag.

    • Main Results:

    • Successful implementation of TIMET and ADC8 programs for neurophysiological signal digitization.
    • Achieved flexible control over A-to-D conversion timing and parameters.
    • Demonstrated high sampling capabilities and efficient data storage.

    Conclusions:

    • The developed microcomputer programs provide a flexible and efficient solution for analog-to-digital conversion of neurophysiological signals.
    • These tools enhance data acquisition capabilities for neuroscience research.
    • The system allows for interactive data visualization and storage.
