    This study introduces a novel scatter diagram to visualize nerve impulse timings in three neurons. The

    Area of Science:

    • Neuroscience
    • Computational Neuroscience
    • Systems Neuroscience

    Background:

    • Understanding neural circuit function relies on analyzing the precise timing of nerve impulses.
    • Existing methods like cross-correlation histograms are limited to analyzing pairs of neurons.

    Purpose of the Study:

    • To develop a new visualization technique for analyzing the temporal relationships of impulse activity in three simultaneously recorded neurons.
    • To establish a method for inferring functional circuitry from neural impulse patterns.

    Main Methods:

    • A scatter diagram technique generalizing cross-correlation histograms was developed.
    • Time intervals between impulses from three neurons were plotted on triangular coordinates.
    • This generated a Joint Impulse Configuration Scatter Diagram, termed a 'snowflake' plot.

    Main Results:

    • The 'snowflake' plot reveals distinct patterns of spots and lines corresponding to specific three-neuron circuit configurations.
    • Illustrative examples of snowflake patterns for various three-neuron circuits are provided.
    • The technique offers a visualizable method for interpreting complex neural interactions.

    Conclusions:

    • The Joint Impulse Configuration Scatter Diagram is a powerful tool for analyzing multi-neuron activity.
    • This method facilitates the interpretation of functional circuitry in neural networks.
    • The catalog of snowflake types aids in the analysis of experimental neuroscience data.
