Cerebral activation related to movement imagery on the unaffected hand (left-sided patients and feigners were flipped).

Coordinates refer to the voxels of maximum activation within significant clusters (P*CP = conversion paresis, NC = normal controls, FC = feigning controls;**k = contralateral/ipsilateral cluster extent, when separate clusters are involved;*** = activation spreads bilateral and included frontal eye fields;****spreads bilaterally.
