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 5

Schematic diagram of corticospinal tract projection in the less-affected hemisphere. Ipsilateral corticospinal tract (iCST) wiring related to the paretic hand (dotted line) was observed on the less-affected side of the pons before decussation of the lower medulla. Due to this iCST projection, the DTI-CST of the less-affected hemisphere cannot reflect purely the less-paretic hand and the DTI-CST of the more-affected hemisphere cannot reflect purely the more-paretic hand.
