We hypothesized that manipulating contrast would influence the rate and prevalence of PHS.
We tested over 200 participants under conditions of differing thermal contrast. As thermal contrast increased, the number of individuals reporting non-painful PHS also increased!

Contrast enhancement emphasizes regions of transition, like edges in visual scenes.
To test our theory that PHS depends on thermal contrast, we adapted classical measures of PHS, the Thermal Sensory Limen task, to manipulate thermal contrast (the distance between warm and cold temperatures).
