Figure 5From: Abnormal nociception and opiate sensitivity of STOP null mice exhibiting elevated levels of the endogenous alkaloid morphine Thermal Nociceptive thresholds and behaviors of WT and STOP null mice. A. Mechanical von Frey thresholds of WT (n = 17) and STOP null (n = 16) mice. B. Thermal hot nociceptive thresholds (B1) and behaviors (B2: total number of jumps between 30 and 43°C) for WT (n = 16) and STOP null mice (n = 16). C. Thermal cold nociceptive thresholds (C1) and behaviors (C2: total number of jumps between 20 and 0°C) for WT (n = 10) and STOP null mice (n = 18). Statistical significance between STOP null versus WT mice is indicated as follow: * p < 0.05, ** p < 0.01, *** p < 0.001.Back to article page
