Review the computational models, signal processing pipelines, and inverse problem methodologies used to localize neural electrical activity with magnetoencephalography and electroencephalography.
Synthesized computational formulations for calculating forward electromagnetic fields from known neural source configurations.
Analyzed parametric and imaging-based mathematical approaches to solve the biomagnetic and bioelectric inverse problem.
Summarized signal processing frameworks including digital filtering, 3D image analysis, blind source separation, and phase synchrony estimation.
Magnetoencephalography and electroencephalography provide temporal resolution below 100 ms, enabling real-time tracking of cell assembly dynamics.
Integration of forward field modeling with parametric and distributed inverse solvers allows noninvasive spatial localization of cortical source generators.
