Analgesia
Thermal Gradient Test
Independent Thermal Test Demonstrates Place Preference and Temperature Comfort Thresholds for Rodents!
As described by Moqrich et al. 2005, our Thermal Gradient Test monitors thermal nociception completely independently on freely moving rodents. A continuous temperature gradient (5 to 55°C) is established over a 120 cm long base plate on which the animal is free to walk. After an exploration period of acclimation, the animal clearly shows a distinct zone preference. Our model is an automated system which maintains the temperature gradient stable over the surface and over time. The accompanying software, coupled to a video camera, displays for each animal the time spent in each temperature zone, together with overall distance travelled. The encrypted data and video images are recorded synchronously in real time during the experiments and the user is able to replay the files to analyze or review.
