Action Training in Stroke Patients

A vast majority of stroke patients with right hemisphere lesions show hemispatial neglect, a severe visuospatial impairment, where they fail to perceive items presented in the contralesional part of space. Currently, it is strongly debated whether these patients also fail to reach out and grasp objects presented in that same space. I will argue that immediate on-line actions are not impaired in neglect. I will also show that neglect patients have difficulties in delayed and anti-pointing tasks which require explicit off-line, allocentric processing and argue that the anatomical areas critically associated with these off-line deficits are located in the temporal lobes. Importantly, I will show that the spared actions can be exploited successfully for stroke rehabilitation.
