Representation of Foreseeable Choice Outcomes in Orbitofrontal Cortex Triplet-wise Interactions. PLos Computational Biology. In short, the experiment consist of an interval discrimination task in rodent. The animal had to access the central socket in order to trigger a sequence of two 50 ms pure tones separated by either a short or a long inter-tone interval; by nose-poking either the left socket (for short ITI) or the right socket (for long ITI) to successfully retrieve the reward. After an incorrect trial, the previous ITI was repeated. Otherwise, the ITI was randomly drawn from a distribution of values which grade the difficulty of the task. The dataset consist of the stimulus characteristics, the behavioral responses and in vivo neuronal recordings in rodent Orbitofrontal Cortex. (see details below and in the paper).
