Correlation between activation parameters (impaired forelimb stimulation-induced ΔCBVmax[act.] in ipsilesional M1/S1fl; laterality index) and cerebral tissue injury (ADC and T2 in ipsilesional M1/S1fl; lesion size) and neurologic status (neurologic score) at 1 (1d), 3 (3d), and 14 d after stroke (14d)
