Presentation
As advised by A. MOQRICH, and published in Moqrich et al (Science 2005, 307: 1468-72), this Thermal Place Preference Test allows researcher to work on unrestrained animals (mice and rats) let free to choose their preferred position (comfort zone) between 2 compartments set at different temperatures. This behavioural assay will allow monitoring temperature preferences, nociceptive thresholds and state in the role of a given gene or a compound on these pain thresholds associated to cold and hot stimulation.
This Temperature Choice Test from Bioseb is investigator-independent, unlike the cold and/or hot plate test: using the traditional plates, an operator can measure the reaction time of an animal (mouse or rat) exposed to a certain temperature. The "two Temperatures Choice Test" will return a nociceptive response without any action from the operator, and the obtained value is a temperature or a temperature range indicating the sensitivity of the animal (mouse or rat) resulting to the exposure to different stimulations (cold or heat).
2 animals (rat or mouse) can be observed simultaneously and independently, making the Thermal Place Preference system remarkably attracting for your analgesia research.
The position of each animal (rodent) can be obtained very easily with the automatic detection software. Results can be transferred directly as an Excel file or as a txt format.
Measured parameters: for each animal, you can retrieve your data as the time spent in each temperature zone, the time of each zone trespassing and the temperature of each zone.
This test is easy to setup :
Using the optional automatic detection software: the operator defines the temperature of each zone. Once the temperatures are stabilized, animals are placed and the acquisition can be launched. The operator doesn't have to be present any more during the nociceptive experiment.
If not using the automatic detection software, temperatures have to be defined manually, and the operator has to measure the time himself.
During the thermal analgesia experience, the operator can visualize the position and movements of each animal on the screen. Raw data acquisition files are stored in a proprietary format to match GLP norms, while a .txt version of the file can be used for further analysis in MS Excel.
Options :
Automatic detection software to measure the position and presence time of the animal (mouse or rat) in each zone, comes with 3 USB cables and a webcam.
