The Effects of 1 mA tACS and tRNS on Children/Adolescents and Adults: Investigating Age and Sensitivity to Sham Stimulation

Figure 2

Analyses on age groups. The main effect of age group as well as all interactions were nonsignificant (all ). An asterisk indicates . (a) Mean SI 1 mV MEP amplitudes (± SEM) of stimulation conditions. The -axis depicts normalized and log-transformed MEP amplitudes. The linear mixed model for the SI 1 mV MEP amplitudes revealed a significant main effect of stimulation (). The post hoc tests for all 43 participants showed significant higher amplitudes following 140 Hz stimulation compared to sham stimulation. (b) Mean SI 1 mV MEP amplitudes (± SEM) of stimulation conditions in the children/adolescents and adults group. The -axis depicts normalized MEP amplitudes. The SI 1 mV MEP amplitudes did not differ between age groups for any of the stimulation conditions (all ). (c) Time course of mean SI 1 mV MEP amplitudes (± SEM) for each age group and each stimulation. The -axis depicts the timepoints before and after stimulation. The -axis displays normalized MEP amplitudes.
