Before revision: To do this, noninvasive neuroimaging methods are typically used to record direct neurophysiological markers of brain activity through electrical activity Electroencephalography (EEG), Magnetoencephalography (MEG) or through indirect metabolic Positron-emission tomography (PET) and neurovascular measures of neural activity including Functional magnetic resonance imaging (fMRI), Functional near-infrared spectroscopy (fNIRS), transcranial Doppler (TCD) sonography.
