Tail flick test apparatus. The tail flick test is a test of the pain response in animals, similar to the hot plate test. It is used in basic pain research and to measure the effectiveness of analgesics, by observing the reaction to heat. It was first described by D'Amour and Smith in 1941. [1]
Example of a traditional set-up for the tail flick assay. The tail flick assay or tail flick test uses a high-intensity beam of light aimed at a rodent's tail to detect nociception. [1] In normal rodents, the noxious heat sensation induced by the beam of light causes a prototypical movement of the tail via the flexor withdrawal reflex. [2]
The hot plate test is a test of the pain response in animals, similar to the tail flick test. Both hot plate and tail-flick methods are used generally for centrally acting analgesic, [1] while peripherally acting drugs are ineffective in these tests but sensitive to acetic acid-induced writhing test. [2] The hot plate test is used in basic pain ...
Nonhuman animal pain measurement techniques include the paw pressure test, tail flick test, hot plate test and grimace scales. Grimace scales are used to assess post-operative and disease pain in mammals. Scales have been developed for ten mammalian species such as mice, rats, and rabbits. [68]

Of Mice and Men is a 1937 novella written by American author John Steinbeck. [ 1 ] [ 2 ] It describes the experiences of George Milton and Lennie Small, two displaced migrant ranch workers, as they move from place to place in California , searching for jobs during the Great Depression .
Rodents have been employed in biomedical experimentation from the 1650s. [1] Rodent studies up to the early 19th century were mainly physiological or toxicological.The first rodent behavioral study was carried out in 1822, a purely observational study [2], while quantitative rodent behavioral testing began in the late 19th century [1] [2].
The main strength of the tail suspension test is its predictive validity– performance on the test can be altered by drugs that improve depressive symptoms in people. Specifically, if antidepressant agents are administered before the test, the animal will struggle for a longer period of time than if not and exhibit more escape behaviors. [1]
