The number of subjects for each experimental condition is listed, along with the gender distribution, the mean age, and baseline TMS metrics (± SD). SI1mV refers to the stimulus intensity required to produce an average motor evoked potential (MEP) of 1 mV. Baseline MEP refers to the average amplitude of the 25 baseline recordings. No factor differed significantly between session and experimental group.
