Adaptation to warming but not cooling at slow rates of stimulus change in thermal threshold measurements

The relationship between thermal detection threshold and rate of temperature change of the thermal stimulus when slow (<1 degrees C s(-1)) rates of change are employed was investigated. Using both the reaction time (RT) inclusive Method of Limits and RT exclusive Method of Levels healthy volunteers had warming (WDT) and cooling detection thresholds (CDT) measured at four different rates of temperature change (0.3, 0.5, 0.7 and 1.0 degrees C...
