      abstract     = {The ability to rapidly establish a memory link between
                      arbitrary sensory cues and goal-directed movements is part
                      of our daily motor repertoire. It is unknown if this ability
                      is affected by middle cerebral artery stroke. Eighteen
                      right-handed subjects with a first unilateral middle
                      cerebral artery stroke were studied while performing a
                      precision grip to lift objects of different weights. In a
                      "no cue" condition, a noninformative neutral visual stimulus
                      was presented before each lift, thereby not allowing any
                      judgment about the object weight. In a "cue" condition
                      arbitrary color cues provided advance information about the
                      weight to be lifted in the subsequent trial. Subjects
                      performed both conditions with either hand. During "no cue"
                      trials subjects scaled their grip force according to the
                      weight of the preceding lift, irrespective of the hand
                      performing the lift or the hemisphere affected. The
                      presentation of color cues allowed patients with right
                      hemispheric stroke, but not those with left hemispheric
                      stroke, to scale their grip force according to the weight in
                      the upcoming lift when lifting the weight with the
                      unaffected hand. Color cues did not allow for a predictive
                      scaling of grip force according to the weight of the object
                      to be lifted when lifting with the affected hand,
                      irrespective of the affected hemisphere. These data imply
                      that the ability of visuomotor mapping in the grip-lift task
                      is selectively impaired in the affected hand after right
                      middle cerebral artery stroke, but in both hands after left
                      middle cerebral artery stroke.},
