Motor Organization in Schizencephaly: Outcomes of Transcranial Magnetic Stimulation and Diffusion Tensor Imaging of Motor Tract Projections Correlate with the Different Domains of Hand Function

Figure 7

Schematic description of the dominance of iMEP according to muscle. iMEP tends to be more predominant in the distal muscle (FDI) than proximal muscles (BB, deltoid) in the upper extremity, which may be attributed to the tendency of iCST withdrawal failure in the distal muscle rather than in the proximal muscles. iMEP: ipsilateral motor evoked potential; FDI: first dorsal interosseous; BB: biceps brachii; iCST: ipsilateral corticospinal tract.
