Functional and structural cortical characteristics after restricted focal motor cortical infarction evaluated at chronic stage – indications from a preliminary study

Highlights • TMS and DWI show changes in chronic stroke patients with minor motor symptoms. • Affected hemisphere is less excitable to produce strong responses. • At chronic stage, neuronal structure remains disrupted in the affected motor cortex.
