Efficacy and Interindividual Variability in Motor-Cortex Plasticity following Anodal tDCS and Paired-Associative Stimulation

Figure 1

Experimental course and design. At baseline RMT and S1mV were recorded for single-pulse (SP) and paired-pulse (PP) TMS-measures. Then, 40 MEP with test stimulus intensity pulses (P), SICI and ICF (15 test stimuli and 10 paired stimuli for each ISI), and IO-curves were obtained followed by either anodal tDCS or PAS. After stimulation 20 MEP were recorded at five different time points for 30 minutes with SICI/ICF and IO-curves measured at 15 and 25 minutes.
