Transcranial Stimulation (tDCS) and Prism Adaptation in Spatial Neglect Rehabilitation

The present study aims to compare the relative therapeutic efficacy of prism adaptation therapy combined with real versus sham tDCS. The investigators will test the hypothesis that the magnitude and duration of neglect improvement will be increased when prism therapy is combined with real tDCS compared to sham tDCS. A second objective is to test whether individual differences in baseline clinical or brain imaging measures can predict: 1) neglect severity or 2) inter-individual differences in patients\' therapeutic response. A third goal is to use brain imaging to characterize the patterns of neural change induced by the intervention to identify brain structures that mediate therapeutic response.
