P105. Network dynamics engaged in the modulation of motor behavior in chronic stroke patients

Affected hand movements are associated with a successive increase of neural activity in both hemispheres in the first weeks after stroke, which then return to levels observed in healthy controls, particularly in patients making full motor recovery. Little is known about the changes of the interplay of brain regions that enable the modulation of motor performance after stroke. In healthy subjects, an important feature of faster hand movements is mediated by a more effective coupling between distinct cortical and subcortical motor areas.
