TMS-fMRI can show the effects of TMS on distal brain regions in different experiments and observe the dynamic connections between brain networks at 100 ms resolution, which is an important progress in exploring time-specific brain region functional connectivity. In the exploration of the interaction between brain regions, TMS-fMRI can evaluate the impact of TMS on the cerebral cortex and the interaction of brain regions, help people understand the neural mechanism behind attention control, and study the brain's processing of somatosensory; TMS-fMRI can also be used to study the pathogenesis and therapeutic effects of neurological and psychiatric diseases, and to study the effects of psychoactive compounds on brain regions.
