Table Note: AIS – Arterial ischemic stroke, PVI – Periventricular venous infarction, cc – Cubic centimeters, Les – lesioned, SC – Structural connectivity, FC – Functional connectivity, CST – Cortical spinal tract, FA – Fractional anisotropy, MD, AD, RD – Mean, axial, and radial diffusivity, M1 – Primary motor cortex, S1 – Primary sensory cortex, SMA – Supplementary motor area. In TDC participants, non-lesioned refers to the dominant hemisphere (left) and lesioned refers to the non-dominant (right) hemisphere.
