The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Accurate localization of cortical and subcortical sources of M/EEG signals by a convolutional neural network with a realistic head conductivity model: Validation with M/EEG simulation, evoked potentials, and invasive recordings (2024, result): “Contrary to the long-held belief that deep brain structures are not discernible via M/EEG, recent studies have shown the potential of these techniques in detecting subcortical activity through simultaneous M/EEG and invasive electrode recordings (Pizzo et al., 2019; Seeber et al., 2019).”
Simultaneous invasive and non-invasive recordings in humans: A novel Rosetta stone for deciphering brain activity (2024, unknown): “Spatial filtering technique or independent component analysis (ICA) can potentially help disentangling signals seen at the surface and thus facilitate the comparison with depth signals (Coelli et al., 2023; L ´ opez-Madrona et al., 2022; Pizzo et al., 2019).”
Combining independent component analysis and source localization for improving spatial sampling of stereoelectroencephalography in epilepsy (2024, methodology): “It is used in non-invasive recordings to remove artifacts 13 or to extract activities of interest such as epileptic discharges or cognitive processes 14,15 .”
