The left side was ipsilateral and the right side was contralateral to the stimulation. Sign indicates whether the structure showed a signal increase or decrease. Percent Δ indicates signal intensity, whereas P value (expressed as 10−x) indicates statistical significance of general linear model (GLM) model fit. Talairach coordinates of the activated cluster are presented with x (medial–lateral), y (anterior–posterior), and z (superior–inferior). The proportion of individual subjects who demonstrated changes seen with group analysis is also given. Subthreshold response denoted by (*).
