OPAD - Orofacial pain assessment device

The OroFacial Pain Assessment Device (OPAD) provides an automated measurement of hot or cold orofacial pain assessment in the trigeminal nerve in rats and mice. Using an operant behaviour conflict paradigm, rodents voluntarily decide between receiving a reward or escaping an aversive stimulus.

The OPAD begins to work when the animal touches and presses between dual peltier-controlled temperature elements to obtain a liquid reward. As the temperature (hot or cold) becomes aversive, the animal can withdraw. The OroFacial Software will automatically track the number of licks, contact with elements, temperature at which contact is broken, and amount of liquid consumed.
