|Outline of Final Research Achievements
We performed two-photon imaging of the mouse parietal cortex during an Auditory Virtual Navigation Task. By using Bayesian decoder of the target location from neural activities, we showed that the target location is updated by prediction even during no-sound periods and that the target location is disambiguated during sound presentation, which are the signatures of Dynamic Bayesian Filtering.
We recorded and analyzed the striatal neural activities of rats during a probabilistic reward task and revealed that the many neurons in the dorsomedial striatum encode action values. We also used a miniature endoscope microscope to image the neural activities of the hippocampus and the striatum and showed that reward predictive responses develop in the striatum during learning of conditioned responses.
