4-Choice Gambling Task (4C-GT) for Mice

Model 89550A

 

Adapted for mice, this test is based on the Iowa Gambling Task, sensitive to serotonergic and dopaminergic agents.

 

Based on the Iowa Gambling Task, the rodent chooses from four illuminated windows. A touch in any of the windows will result in either a Win (food reward is delivered) or a Loss (timeout period with no reward). Each window is associated with a different amount of reward. The larger the associated reward, the lower the probability of receiving a Win and the longer the timeout if the trial results in a Loss. The subject must learn to avoid the high-risk, high-reward options in order to maximize earnings. The test is sensitive to serotonergic and dopaminergic agents.
