Laterality of Poststroke Cortical Motor Activity during Action Observation Is Related to Hemispheric Dominance
Figure 5
Laterality index in regions of interest. Left: nondisabled participants, middle: participants with left hemisphere stroke, right: participants with right hemisphere stroke; each during left hand (blue) and right hand (red) action observation; in the inferior frontal gyrus pars opercularis (IFG-Op), inferior frontal gyrus pars triangularis (IFG-Tri), supramarginal gyrus (SMG), and precentral gyrus (Precentral). . Positive values indicate left hemisphere laterality; negative values indicate right hemisphere laterality.
