Deep brain stimulation stops limb tremors in Parkinson's patients. But positioning the stimulation electrode in the brain must be done very precisely to avoid undesired side-effects.

She has found an ingenious way to localize this 'magic area': by using MRI to visualize the pathways in the brain that lead to it. read more..
