Brain activation can be evaluated by a bimodal fMRI protocol that utilizes hemodynamics based fMRI and manganese-enhanced MRI (MEMRI) in combination. The present study demonstrates a striatal CBV response accompanied by enhanced nigrostriatal activity detected by MEMRI following peripheral electrical stimulation.
