Analgesia
Thermal Place Preference
This behavioral assay will allow monitoring of temperature preferences, nociceptive thresholds and investigate the role of a given gene or compound on these thresholds. As advised by A. Moqrich and published in Moqrich et al (Science 2005, 307: 1468-72), this test allows researchers to work on unrestrained animals whom are free to choose their preferred position between two compartments at different temperatures. Completely investigator-independent, the Two Temperature Choice Test elicits a nociceptive response from the subject. The obtained value is a temperature or temperature range indicating the sensitivity of the subject. Using automatic detection software (optional), the user sets the temperature of each zone, defines a protocol of temperature changes or ramps, and starts the measurement process. Two animals can be observed simultaneously and independently, making the system remarkable efficient. The animals are video tracked and the software records their position vs. temperature and time. When the optional automatic detection software is not used, temperatures must be defined manually and the user must measure the time and animal position.
