The MNI standardized stereotaxic coordinates (mm) representing changes in cerebral blood flow. x, medial‐to‐lateral distance relative to the midline (positive, right); y, anterior‐to‐posterior distance relative to the anterior commissure (positive, anterior); z, superior‐to‐inferior distance relative to the anterior commissure‐posterior commissure line (positive, superior).
