Grand-average change from baseline in MEP amplitude recorded from the right FDI muscle at 5–60 min following cTBS of the left motor cortex in ASD and NT subjects with BDNF Met− genotype. Error bars represent standard error of the mean. ASD, autism spectrum disorder; BDNF, brain-derived neurotrophic factor; cTBS, continuous theta-burst stimulation; ΔMEP, natural log-transformed, baseline-corrected amplitude of motor evoked potential; FDI, first dorsal interosseous; Met, metionine; NT, neurotypical.
