Altered structural and functional connectivity between the bilateral primary motor cortex in unilateral subcortical stroke

A large number of functional imaging studies have focused on the understanding of motor-related neural activities after ischemic stroke. However, the knowledge is still limited in the structural and functional changes of the interhemispheric connections of the bilateral primary motor cortices (M1s) and their potential influence on motor function recovery following stroke. Twenty-four stroke patients with right hemispheric subcortical infarcts...
