Researchers successfully traced the flow of dopamine using functional MRI with paramagnetic haem protein BM3h as a contrast agent in the ventral striatum. The tracer was injected into live mice, and the medial forebrain bundle was electrically stimulated. The approach allowed identification of areas of high dopamine concentrations. The technique described in the journal Science could be used to study Parkinson's disease, according to researchers.
