Fig. 5: a) The psychophysical threshold, computed as the 50% just noticeable difference for comparing the sensory thresholds (median±IQR) of thumb,index and middle fingers for both gratings. b) 50 % psychophysical thresholds for all finger types across both types of gratings were averaged for each participants. The resulting thresholds (median±IQR) were compared between the right and left hand. c) The same procedure was performed to compare the psychophysical thresholds (median±IQR) between both types of gratings.
