Mice Are Trained on a Difficult Auditory Detection Task

We trained mice on a difficult tone in noise detection task. The animals were sitting on a rotating cylinder and were free to walk. They heard random series of noisy auditory stimuli. If the stimulus contained a pure tone, then the animal could lick for a liquid reward. If the animal missed the tone or licked at the wrong time, he got a time out. The intensity of the tone was varied randomly above and below threshold for detection, making the task difficult to perform perfectly.
