    Summary

    This study introduces a new neuromagnetic data analysis method to investigate synchronized spontaneous activity (SSA). The technique successfully distinguished two distinct signals from a single evoked response, suggesting separate neural sources.

  • Resolution of distinct signals within a single evoked response.

    • Main Results:

    • The novel approach successfully resolved two different signals from a single evoked response.
    • Evidence was provided for the existence of two possibly distinct neural sources.
    • The findings support a model where sensory stimuli can synchronize spontaneous neural activity generators.

    Conclusions:

    • The presented technique offers a powerful new tool for analyzing neuromagnetic data.
    • This method advances the study of synchronized spontaneous activity (SSA) and neural source localization.
    • The results contribute to understanding the dynamic interplay between spontaneous neural activity and sensory stimulation.
