If escape is impossible, the animal will eventually stop trying (\u201cgive up\u201d). In the tail suspension (TST), a mouse is suspended by the tail so that its body dangles in the air, facing downward. When the animal stops struggling and hangs immobile it is considered to have \u201cgiven up\u201d.\u00a0 Longer periods of immobility are characteristic of a depressive-like state.<\/p>\n\n\n\n<p>Antidepressants reduce immobility.<\/p>\n\n\n\n<p>Some strains (e.g., C57BL\/6J) may not perform well in the TST due to tail climbing behaviour. Strains with vestibular deficits may show an abnormal spinning phenotype and should also not be used in the TST. Other mouse phenotypes that display neurological abnormalities that lead to unusual leg clasping behaviour or that influence immobility times may also not be appropriate animals for this test<sup>1<\/sup>.<\/p>\n\n\n\n<p>1.
