Fig. 5From: Quantitative neuromagnetic signatures of aberrant cortical excitability in pediatric chronic migraineThe latencies of the first and second spectral components in 5–100 Hz in chronic migraine subjects, acute migraine subjects, and healthy control subjects. The x-axis measures time in milliseconds. The bars show the mean and standard error of latencies of spectral components in each group of subjects. The double asterisk indicates p < 0.001; and a single asterisk indicates p < 0.01Back to article page
