| Outline of Final Research Achievements |
The neuronal activity underlying the value-based decision makings depends on the satiety state of animals. I investigated the neural basis for this function during three years: H27-H29. I recorded the neuronal activity from the striatum, which are thought to play crucial roles in this process, and analyzed the data, that brought the following two conclusions.
First, neurons in the ventral striatum showed stronger value modulation with a shorter latency of their responses compared to dorsal striatum one.
Second neurons in the ventral striatum reflect expected values of rewards in contrast to the dorsal striatum neurons, which reflect probability or magnitudes of rewards, individually.I will publish this result soon, while I have seven publications as a part of this research project during the three years.
