| Outline of Final Research Achievements |
The aim of this study was to image the activities of the neurons which regulate decision making and ultimately to elucidate the neural mechanisms of decision making by taking advantage of the minimum size of the telencephalon of the adult zebrafish. We revealed that two different neural ensembles in the telencephalic pallium encode the behavioral rules for escape and stay. We also showed that the activities of the neurons in the ventral habenula and their direct targets, the serotonergic neurons in the median raphe,encode the expectation value of the future negative reward. We further have succeeded in establishing the virtual reality environment in which the neural activities of the whole brain of live adult zebrafish can be observed.
