Acupuncture Enhances Communication between Cortices with Damaged White Matters in Poststroke Motor Impairment

Figure 4

FC alterations before and after acupuncture intervention in stroke patients and healthy controls. Connected by the SLF-FP, the adjoining PM and SMA had conspicuously increased FC with the SMG under acupuncture intervention in stroke patients. The green color indicates the stroke patients. The blue color indicates the healthy controls. P < 0.01 versus before acupuncture intervention; P < 0.001 versus the group of healthy controls. FC, Functional connectivity; PM, premotor cortex; SLF-FP, frontoparietal part of the superior longitudinal fasciculus; SMA, supplementary motor area; SMG, supramarginal gyrus.
