The Neurobehaviour Core

Tail Suspension Test



To test for failure, to try to escape an aversive stimulus.



Tail Suspension Test (TST) measures the duration of immobility that is inferred as an index of behavioural despair (the animal has resigned escaping). Following an initial period of vigorous struggling, the animal gradually abates into immobility. Duration of immobility detected in the TST is sensitive to antidepressants action. TST is a good tool to study the neurobiology of depression in gene-modified mice.
