Mingyur went through another batch of tests, this time with fMRI, which renders what amounts to a 3-D video of brain activity. The fMRI gives science a lens that complements the EEG, which tracks the brain’s electrical activity. The EEG readings are more precise in time, the fMRI more accurate in neural locations. An EEG does not reveal what’s happening deeper in the brain, let alone show where in the brain the changes occur—that spatial precision comes from the fMRI, which maps the regions where brain activity occurs in minute detail.
