Coordinates [x, y, z] refer to the Montreal Neurological Institute (MNI) standard stereotactic space.
LOI = Leyton Obsessional Inventory; NAcc = nucleus accumbens; PMd = dorsal premotor cortex; PFC = prefrontal cortex; SLF = superior longitudinal fascicle I, II or III; SI = primary somatosensory cortex.
