WebSep 1, 2024 · The spatial resolution of EEG is lower as compared to other imaging methods. Still, an important role is being played by EEG as the temporal resolution of EEG is higher than other MRI imaging methods. Also, neuronal activation is directly accessible through EEG [ 5 ]. Thus, EEG is one of the clinically acknowledged diagnostic methods [ … WebEEG can readily have a high temporal resolution, (although sub-millisecond resolution generates less meaningful data), because the two to 32 data streams generated by that number of electrodes is easily stored and processed, whereas 3D spatial technologies provide thousands or millions times as many input data streams, and are thus limited by …

WebElectroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) stand as state-of-the-art techniques for non-invasive functional neuroimaging. On a unimodal basis, EEG has poor spatial resolution while presenting high temporal resolution. WebJan 15, 2009 · EEG-only source localization is an inherently underconstrained problem, whereas fMRI by itself suffers from poor temporal resolution. Combining the two modalities transforms source localization into an overconstrained problem, and produces a solution with the high temporal resolution of EEG and the high spatial resolution of fMRI.

WebThe biggest potential advantage of MEG over EEG is that it permits a much better spatial resolution in addition to the excellent temporal resolution. One MEG study showed that the M170 (equivalent to the N170 of ERP) is sensitive both to facial expressions (angry, happy, neutral) and to facial orientation that may indicate status (aloof or ...
