Fig. 2

The change in intensity of different sensations (∆ values, means ± SEM, panels ae) occurring by moving from the uniform temperature condition (20 or 40 °C) to the thermal grill condition (20 and 40 °C interleaved). To assess sex differences, Student’s t test for unpaired samples was performed and significant differences are marked by asterisks. In panel e, sensations evoked by the 20 or 40 °C stimulus were pooled because stimulation with uniform temperatures did not induce any pain sensation
