Activity of the brain is study outside of the head by this particular technique in which the magnetic fields emitted by changes in brain activity is picked up.
A)transcranial magnetic stimulation (TMS)
B)functional magnetic resonance imaging (fMRI)
C)electroencephalograms (EEGs)
D)magnetoencephalography (MEG)

Question

Quizplus · Accepted Answer

Magnetoencephalography (MEG) specifically picks up on the magnetic fields emitted by changes in brain activity, meaning that it can study brain activity outside of the head using this particular technique. Transcranial magnetic stimulation (TMS) is a technique that can stimulate brain activity, while functional magnetic resonance imaging (fMRI) and electroencephalograms (EEGs) both measure changes in blood flow and electrical activity in the brain, respectively, but not necessarily magnetic fields.
