title: Exploratory-motor task to evaluate right frontal lobe damage.
abstract: An exploratory-motor (E-M) task was performed by 20 patients with right hemispheric damage and unilateral spatial neglect and by 15 adult controls. None of the subjects in the control group demonstrated E-M neglect, other types of unilateral spatial neglect, or motor impersistence. In the unilateral spatial neglect group, 14 of 20 patients revealed E-M neglect. The presence or absence of E-M neglect related to word fluency, digit span recall (backward), and motor impersistence. In addition, E-M neglect frequency was observed in patients with lesions in the frontal lobe. The frontal lobe may play an important role in the performance of an E-M task. Therefore, we think that E-M task performance is a useful method for evaluating the site of right frontal lobe damage.
