WebApr 12, 2024 · In contrast, the EEG (electroencephalogram) measures the electrical activity of the neurons right underneath the electrodes itself and provides high temporal resolution, unlike fNIRS. However, a simultaneous recording of both fNIRS and EEG signals in one single device is highly beneficial.

WebThe specific appeal of the combination is related to the fact that both methods are complementary in terms of basic aspects: EEG is a direct measurement of neural mass activity and provides high temporal resolution. FMRI is an indirect measurement of neural activity and based on hemodynamic changes, and offers high spatial resolution. WebConsidering the specificity of neuronal activity assessment using the neuroimaging modality of EEG, which can measure the dynamics of a neural network with excellent temporal resolution and allows for an examination of the whole-brain network functional connectivity in many frequencies, our results await further investigation into whole-brain ...

WebDec 31, 2024 · In contrast to fMRI, EEG can capture the electrical activity with a high temporal resolution (typically in milliseconds).
