Stimulation target refers to the cortical area controlling the named muscle (abductor pollicis brevis or abductor digiti minimi). In dataset 10, no hand muscle areas were found and stimulation was given to area usually responsible for controlling the right hand. The stimulus intensities are given with respect to the resting motor threshold (MT) intensity. When noise masking was given, it was adjusted until the subject reported to not hearing the click. Interstimulus interval (ISI) either varied randomly between 2 and 3 s or among 1, 3, and 5 s.
