title: Dominant limb motor impersistence associated with callosal disconnection.
abstract: Motor impersistence occurs more frequently after right than left hemispheric lesions. Following a callosal lesion, motor impersistence may thus occur more frequently in the right (dominant) than left limb. After an infarction involving the right medial frontal lobe and corpus callosum, a 66-year-old right-handed man demonstrated right limb motor impersistence on bedside evaluation, which was substantiated experimentally. Results demonstrated hemispatial effects with greater impersistence in the neglected (right) space.
