Thermal sensory and pain thresholds. The effect of the two drugs (morphine and buspirone) on the tested thermal sensory qualities: a) HDT, b) HPDT, c) CDT and d) CPDT. Data are expressed as means ± SD of the difference between the baseline threshold values measured before and 60 or 120 minutes after the administration. * = statistical significance of change in threshold compared to pretreatment (p < 0.05). HDT = heat detection threshold, HPDT = heat pain detection threshold, CDT = cold detection threshold, CPDT = cold pain detection threshold.
