Feasibility of blood–brain barrier opening using MRgFUS in the hand control region of the right primary motor cortex. a Hand control region mapping using motor-task functional MRI (fMRI). b, c show confirmation of successful blood–brain barrier permeabilization in the sonicated primary motor cortex area as demonstrated by new gadolinium enhancement in T1-weighted imaging. Subject two is represented in the top row and subject three in the bottom row
