Two studies reported declined FA in the corticospinal tract[21] and increased MD in the corpus callosum,[22] respectively, with insignificant changes in the cortical GM.
One hypothesis posits that mirror movements occur because of abnormally uncrossed corticospinal fibers originating in primary motor cortices (M1) (23).
Testing of the muscle strength of individual muscles such as the deltoid, neck flexors or trapezius with the Oxford grading scale was conducted taking into account the combined nerve innervations of the respiratory muscles and the deltoid, neck flexors and trapezius muscles via the corticospinal pathway and the possibility of interneuron activation (C1 - C6).

Transcranial magnetic stimulation (TMS) and its motorevoked potential (MEP) have been widely used to study corticospinal excitability and connectivity noninvasively [1].
Although transcranial magnetic stimulation studies suggest that corticospinal motor pathways are fully developed in early adolescence [31, 32], there is other evidence suggesting further development of the motor cortex and its associated cortical oscillations well into the adolescent period.
