The first two columns give values for resting motor threshold (rMT) and the intensity required to evoke a 1 mV p-p MEP response (both expressed as percentage of maximum power output). The last column gives the actual MEP amplitude achieved in each condition to approximate the 1 mV target value. Errors are standard error of the mean. Asterisks represent statistically significant differences between rows in the columns (p < 0.05).
