| Abstract(in English) | Decision making in a dynamic environment rests critically on the identification of the environmental dynamics. When the environment is partially observable, it is neccessary to estimate the hidden state using the uncertain observation is needed. Despite considerable interests in the estimation function of the prefrontal cortex, the functional dissociation between the hidden state estimation and dynamics identification has not been studied yet. In this study, we designed a decision making task in which the subjects were required to estimate both the hidden state and the dynamics model using the uncertain information, as an extention of 'Tiger problem' a typical partially observable problem. Our fMRI results showed that the activation of the left anterior prefrontal cortex and the right lateral prefrontal were correlated with the uncertainty of state and dynamics estimation, respectively. |
