Visuospatial neglect is a common neurological symptom which appears following strokes on regions of the right hemisphere of the brain. It affects patient's self representation and awareness of the space, impairing functional rehabilitation and adaptation back to a normal life. The primary purpose of this protocol is to assess the impact of 10 daily sessions of a non-invasive brain stimulation technique, low frequency repetitive Transcranial Magnetic Stimulation (rTMS), applied on the intact hemisphere of the brain to treat post stroke visuospatial neglect at the chronic stage. The hypothesis is that a regime of real but not sham rTMS on the left posterior parietal cortex of the brain will long-lastingly ameliorate visuospatial neglect in stroke patients as revealed by clinical paper-and-pencil and computer-based tests assessing search, detection and discrimination of stimuli presented in different areas of the visual field.
