Mean (±SEM) X, Y, and Z co‐ordinates in Montreal Neurological Institute space within the contralateral dorsal posterior insular cortex following injection of hypertonic saline (5%) into the masetter, deltoid, flexor carpi radialis, first dorsal interossous, and tibilais anterior muscles

	X (±SEM)	Y (±SEM)	Z (±SEM)
Face [masetter muscle: (Nash et al.,2009)]	37.3 ± 0.8	−15.4 ± 0.8	12.2 ± 0.8
Shoulder (deltoid muscle)	37.1 ± 0.6	−15.5 ± 0.8	15.5 ± 1.0
Forearm (flexor carpi radialis muscle)	37.7 ± 0.6	−18.6 ± 0.9	15.7 ± 0.9
Hand (first dorsal interosseous muscle)	38.6 ± 0.5	−17.1 ± 0.8	14.6 ± 1.1
Leg [tibialis anterior muscle; (Henderson et al.,2007)]	36.1 ± 0.6	−18.5 ± 1.0	14.7 ± 0.8

Images used for the analysis of masetter and tibialis anterior muscle pain were collected in previous studies.
