Stroke researchers have confirmed that damage to the right frontal-subcortical network may cause ipsilateral spatial neglect. More patients with ipsilateral neglect had frontal subcortical damage than anticipated -- 83 percent vs the expected 27 percent. A difference was also seen in spatial bias, ie, the type of spatial errors among this group tended to be 'where'(perceptual-attentional) rather than 'aiming' (motor-intentional) errors.
