Why might a researcher be justified in wanting to use transcranial magnetic stimulation (TMS)?
A) If correctly targeted, TMS can generate auditory hallucinations of whatever speech sounds the researcher is interested in investigating.
B) When "naturally occurring" damage interferes with brain activity, it often affects many brain regions beyond those the researcher can hypothesize about.
C) The pulses of magnetic stimulation are totally reversible and will not affect the functioning of the brain after they are turned off.
D) Brain disorders do not occur naturally in children during the ages when they are learning to produce speech.

Question

Quizplus · Accepted Answer

TMS can be used to target specific regions of the brain and investigate their function, but if "naturally occurring" damage has affected multiple brain regions, TMS can still be used to investigate the remaining functional regions. However, options A, C, and D are incorrect as TMS should not be used to purposely induce auditory hallucinations, the effects of TMS are not always completely reversible, and brain disorders can occur in children.
