Fig. 4From: Electroencephalographic spectral power as a marker of cortical function and disease severity in girls with Rett syndromeEEG stability over time in girls with RTT versus TD controls. Change scores were calculated by subtracting power (log10 transformed) in each frequency band at visit 1 from power at visit 2. Data are reported as individual values with lines representing the mean and standard error of the mean. a Change scores in girls with RTT vs. TD controls in the frontal ROI. b Change scores in girls with RTT vs. TD controls in the central ROI. c Change scores in girls with RTT vs. TD controls in the temporal ROI. d Change scores in girls with RTT vs. TD controls in the occipital ROI. TD typically developing, RTT Rett syndrome. Asterisks indicate significance. *p < 0.05Back to article page
