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

Model 89550A


  • A test of impulsivity and decision making
  • All training paradigms and advice included
 

Details

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.
