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

Figure 1

Design of the study. The figure illustrates the procedure for each experimental session. In the beginning of each session, 20 baseline single-pulse MEPs of SI 1 mV amplitude, RMT, AMT, and SICI/ICF were recorded. Afterwards, 1 mA tRNS, 20 Hz tACS, 140 Hz tACS, or sham stimulation was applied over the left primary motor cortex for 10 minutes, and then the SI 1 mV, SICI/ICF were recorded again directly as well as 30 and 60 minutes after stimulation (T0-T60). After finishing each experimental session, the participant was asked to complete a stimulation side effects questionnaire.
