using the OroFacial Software, a module of our popular ANY-maze software. Modulation of the system with hydrolase inhibitors of anandamide (AEA) or 2-arachidonyl glycerol (2-AG) has proved effective in reducing migraine-like features in animal models of migraine. ANY-maze is a flexible video tracking system designed to automate testing in. This model may help elucidate the underlying neural mechanisms that mediate the effects of repeated stress on orofacial pain. The endocannabinoid system exerts an important role in pain processing and modulation. These findings suggest that repeated stress can produce hyperalgesia, which is, at least in part, due to alterations in the activity of opioid systems.

The stressed rats displayed decreased morphine effects on nociception compared to unstressed controls. Anxiety-like behaviors and re- sponse to acute and chronic noxious stimuli were assayed using the elevated plus maze, eye wiping test, and orofacial formalin. After 40 days of restraint, morphine was injected i.p. Rats submitted to acute restraint presented a performance similar to unstressed controls in the TMJ formalin test, whereas chronically stressed rats showed an increase in nociceptive responses.

Then, animals were killed immediately to collect blood for hormonal determinations by radioimmunoassay, or submitted to the TMJ formalin test to evaluate nociception.

Animals were initially submitted to one session of acute restraint stress (1 h) or exposed to chronic stress (40 days-1 h/day). energy from fat (free of animal origin) Diet with 70 energy from fat, obesity-inducing.

The maze was placed 50 cm above the floor in a 5 lux illuminated room and consisted of two open arms and two closed arms (5 × 30 cm and 15 cm wall height for the closed arms). Diet with 60 energy from fat, obesity-inducing. In this study, the temporomandibular joint (TMJ) formalin test was used to evaluate the effects of acute and chronic restraint stress on nociceptive responses in rats. The elevated plus-maze test was performed on the next day of the open-field test, unless otherwise noted. The activity levels of animals housed in the enriched environment, as measured by rearing events and duration, were significantly less than those exhibited by rats in. However, the influence of stress on an experimental deep nociception model is not understood. There was no significant effect of test day on rearing behavior, but there was a significant effect of housing on rearing events (F 1,48 39.168) and duration (F 1,48 10.238).

It has been reported that stress can alter nociception from superficial tissues, such as skin and subcutaneous region.
