Background

  • One of the few methods available for orofacial preclinical research.
  • Orofacial pain is one of the most common neurological complaints.
  • The Orofacial Stimulation Test by Ugo Basile uniquely measures hypersensitivity to thermal or mechanical stimulation of the trigeminal nerve in rats and mice
  • Fehrenbacher, Henry, Hargreaves method, hence the credibility of highly cited scientists
  • Integrates higher-order brain (cognitive) functions into measurements of orofacial nociception

High throughput, simultaneous measurement

  • Rats voluntarily access a food reward or avoid the aversive stimulus.
  • Simultaneous measurement of nociceptive responses to thermal and/or mechanical stimulation.
  • Non-invasive - does not require shaving. Stimulator contacted with animal vibrissae pad.
  • Metrics include duration of feeding and the number of feeding attempts measured by interruption of an infrared barrier as the animal attempts to obtain the reward.
  • Water temperature can be adjusted from ambient to 70ºC.
  • High throughput - data from up to 16 cages can be recorded simultaneously and displayed in real time using ORO-Software.
  • Data can be displayed in numeric and graphic format.
  • Data are automatically analysed across time according to an adjustable time window, independently viewable for each of the 16 cages. 
  • Test results can be saved in spreadsheet format for easy transfer to other programs for more analysis.
  • Adaptors for Mice are available. 
  • Device fits in standard home cages for easy training and testing

Orofacial pain problems are common and involve structures and mechanisms unique to the trigeminal nerve. Few methods are currently available for orofacial preclinical research, and none incorporates parallel measurement of mechanical or thermal stimulation within the same experiment.

Moreover, while most of the current assays measure unlearned behaviors, such as flinching or withdrawal reflexes, the new Orofacial Stimulation Test, developed by Fehrenbacher, Henry and Hargreaves, integrates higherorder brain functions into measurements of orofacial nociception.

This innovative approach permits highly integrated nociceptive responses to thermal or mechanical stimulation.

Animals are trained & tested in standard home cages. Tests are performed in the presence of thermal or mechanical stimuli contacting the vibrissal pad. Following treatment to induce hypersensitivity, (e.g., trigeminal ligation or injection) trials are repeated to determine the effect of treatment on feeding behavior/reward. Assay sensitivity (inflammation-induced decreases in feeding behavior and reversal of hypersensitivity by local and systemic administration of analgesics) has been proven (Hargreaves et alia, ms in prep.); the feeding behavior is strongly correlated to mechanical or thermal orofacial nociception, as the animal must contact the stimulator in order to access the food reward.
