Models of nociception: hot-plate, tail-flick, and formalin tests in rodents.
Experimental models of pain include tests of response thesholds to high intensity stimuli (acute pain tests) and changes in spontaneous or evoked behavioral responses in animals with peripheral injury or inflammation (persistent pain models). Acute thermal pain is modeled by the hot-plate and tail-flick test, while persistent pain can be modeled by the formalin test. This unit presents protocols for all three of these tests, including preparation of animals (rats or mice), administration of a compound being tested for its analgesic properties and data collection.

There are now three models of neuropathic pain in the rat that are in widespread use: the chronic constriction injury, the partial sciatic ligation model, and the spinal nerve ligation model. The procedures to create these models and the behavioral assays used to quantify the resulting abnormal pain sensations are described in this unit.

A more complete understanding of alcohols reinforcing actions is obtained when multiple behavioral procedures are used, some of which bypass taste factors. This unit describes a method for assessing the reinforcing effects of alcohol in mice using the most widely accepted procedure for assessing drug reward: intravenous self-administration.
