In what way is transcranial magnetic stimulation (TMS) different than other techniques researchers use to study brain activity, such as PET scans, fMRIs, and MEG?
A) TMS requires the use of radioactive materials.
B) Other techniques take much longer to acquire data compared to TMS.
C) TMS records the activity of glial cells as well as neurons.
D) TMS is used to actually change the activity in the brain by either stimulating or disrupting activity.

Question

Quizplus · Accepted Answer

Transcranial magnetic stimulation (TMS) differs from other brain imaging techniques such as PET scans, fMRIs, and MEG in that it is used to physically change the activity in the brain through stimulation or disruption. Other techniques simply record existing brain activity without altering it. TMS does not require radioactive materials and does not record glial cell activity. While TMS is relatively fast, other techniques such as EEG can provide even faster data acquisition.
