EEG + MEG

The combination of Electroencephalography (EEG) and Magnetoencephalography (MEG) offers a powerful approach to studying brain activity by integrating their complementary strengths. EEG measures the electrical potentials generated by neuronal activity on the scalp, providing excellent temporal resolution (milliseconds) but limited spatial resolution due to signal distortion by the skull and scalp. MEG, conversely, measures the magnetic fields produced by the same neuronal currents, offering superior spatial resolution for localizing brain sources, especially in deeper cortical areas, while also maintaining high temporal resolution. By combining these two modalities, researchers can achieve a more comprehensive spatiotemporal understanding of brain function, allowing for precise localization of neural sources in time, which is invaluable for both basic neuroscience research and clinical applications like epilepsy surgery planning.

• Comprehensive Spatiotemporal Resolution: Combines EEG's temporal precision with MEG's superior spatial localization.
• Complementary Signal Information: Measures both electrical (EEG) and magnetic (MEG) aspects of neural activity.
• Enhanced Source Localization: Improves the accuracy of identifying where brain activity originates.
• Clinical Diagnostics: Particularly valuable for pre-surgical mapping in epilepsy and understanding functional brain networks.
