Combining fMRI and TMS allows investigators to test causal inferences of neural function, which cannot be done by using only one of these methodologies. fMRI measures changes in blood flow that are associated with neural activity, but it cannot establish causality. TMS can cause a temporary disruption of neural activity in a specific area, allowing investigators to infer causation. Combining the two methods provides a way to establish a causal relationship between neural activity and behavior. The other options (A, C, and D) can be achieved using either fMRI or TMS alone.
