Group data for the effect of stimulation intensity on TMS maps (n = 12). Three different stimulation intensities (110, 120 and 130 % of resting motor threshold) were compared. All statistical testing was performed using the non-parametric Friedman Test and any significant difference were further explored using the Wilcoxon Signed-Rank Test. Statistical significance between pairs was declared when P < 0.017 (Bonferroni adjusted) and is indicated by *. a, b Group data for both x- and y-coordinate of the centre of gravity. No effect was found for stimulation intensity. c–e Group data for the effect of stimulation intensity on map area, map volume and aspect ratio. A significant effect of stimulation intensity on map area and volume was found with all pairs being significantly different. No effect was found for stimulation intensity on the aspect ratio
