A03Dialogue between the predictive coding and brain mechanism for active inference

　The free-energy principle tries to offer an integrated account for the different brain functions. It advances a Helmholtz’s note to regard the brain as a homeostatic system for information. It is based on the predictive coding that the brain minimizes the prediction error (free-energy). However, it is not fully validated by experimental findings. It remains to be solved how a template for prediction can be conveyed and updated in the brain. The present study aims to elucidate the mechanism of active inference through a dialogue between the predictive coding and the experiments of humans and non-human primates. Our results will provide a new insight on how the brain orchestrates different modules for an adaptive function or a new direction for artificial intelligence.
