| Outline of Final Research Achievements |
The imitative learning can be viewed as a process of integrating the external world into the neural representation. To study the neural representation of external world and its influence the action selection, we used both songbirds and mice. In songbird studies, we recorded neural activity in the higher vocal area and its surrounding regions. In mice studies, we found that mice can learn the meta-parameter of the task, i.e., when the task parameter changes. Well learned mice often made predictive actions such as changing the action just before or right on the timing of task parameter changes. We performed two-photon calcium imaging to observe neural activities of the mouse frontal cortex and found that those neurons represented the value of future action guided by the model of the external world.
