Altered amplitude of low‐frequency fluctuations and regional homogeneity in drug‐resistant epilepsy patients with vagal nerve stimulators under different current intensity

Abstract

The spontaneous neural activity changes in DRE patients caused by VNS were in an ongoing process. Increased ALFF/ReHo in frontal cortex, cingulate gyri, precentral/postcentral gyri, parahippocampal gyri, precuneus, parietal cortex, and cerebellum may implicate in VNS-induced improvement in seizure frequency.
