According to question, in this situation we should use fMRI (Functional magnetic resonance imaging ).
An fMRI scan is a unique form of MRI that demonstrates how various brain regions function. They enable medical professionals to measure brain blood flow without the need for surgery. A safe, non-invasive method of diagnosing conditions and determining whether specific treatments are effective is fMRI imaging.
By monitoring changes in both the blood's oxygen content and blood flow, fMRI can identify brain activity. The use of fMRI data as markers for specific mental processes can provide information about the processes that are active when performing various tasks.
