Michael, a researcher in the field of neuroscience, has a theory about a specific area of the brain causing difficulties in face recognition. To draw a solid causal inference, he intends to test his hypothesis on dogs by disrupting regions of their brains and examining the effects of this disruption on the dogs’ face-recognition capacity. Which of the following techniques should be used by Michael to achieve his purpose?a. transcranial magnetic stimulation (TMS)b. computarized axial tomography (CAT scan)c. functional magnetic resonance imaging (fMRI)d. magnetic resonance imaging (MRI)
