Shifting attention in viewer- and object-based reference frames after unilateral brain injury

► 29 unilaterally brain injured patients (13 left, 16 right). ► Reaction time measured for vertical midline and lateral targets. ► Viewer- and object-based reference frames probed. ► Spatial impairments map onto object-based reference frames contralesionally. ► Side of brain injury did not modulate object-based effects.
