Controlled lamp temperature (CLT) on the underside of glass floor produces reproducible epicutaneous thermocouple temperatures (ETT) on plantar hind paw of anesthetized rats. Representative digital oscilloscope traces (a) illustrate CLT (lower panel) and ETT (upper panel). The stimulator was set to 40.0°C for the first stimulation and increased in 2.5°C steps to a cut-off temperature of 70.0°C. Each temperature was applied 4 times per animal and 24 traces were obtained from 6 animals. Second-by-second ETT values were averaged from the 24 traces, and are shown in b. Each data point represents the average ETT ± SEM.
