Electroencephalogram (EEG), magnetoencephalogram (MEG), event-related potential (ERP), and functional magnetic resonance imaging (fMRI), and brain-computer interface (BCI) techniques are covered, with an emphasis on the biophysical basis of acquired signal, source localization, and valid post-processing of data.
Among the techniques that are being used, we can mention the following: ERPs, magnetic resonance imaging (MRI), fMRI, single photon emission computed tomography (SPECT), PET, magnetoencephalogram (MEG), repetitive transcranial magnetic stimulation (rTMS), etc.
Edwin May, Wanda Luke, Virginia Trask, and Thane Frivold provide an abstract of an experiment in which the root mean square phase shift in a percipient's magnetoencephalogram corresponded, not only to sinusoidal gratings presented to an agent, but also to "pseudostimuli" (control stimuli consisting of simple time markers during the experiment).
