| This is a test of learned
helplessness and measures immobility, climbing and swimming
behaviors. When rats or mice are forced to swim in a deep
cylinder with tepid water they become nearly immobile and
cease trying to escape. This characteristic immobile posture
is thought to reflect a depressive-like state and is readily
influenced by a wide variety of antidepressants. In rats,
this can pick up differences in the effects of SSRIs vs
Tricyclic antidepressants. | |
|
|
|  |
|
| Tricyclics (Desipramine) show decreased immobility and increased climbing, while SSRI's (Fluoxetine) show decreased immobility and increased swimming in the rat forced swim test. |
|
|  |
|
| Reduced immobility and increased climbing are observed with the SNRI (Venlafaxine) in the rat forced swim test. |
|
|  |
|
| The effect of triple reuptake inhibitors, Desipramine and DOV 21947 as observed in the rat forced swim test. |
|
|  |
|
| Significantly more climbing observed with desipramine and significantly more swimming observed with buproprion in the rat forced swim test. |
|  |
|
| DBA mice are the most responsive to Sertraline in the mouse forced swim test.. |
