| Outline of Final Research Achievements |
In this study, we tried to estimate the activity propagation path in the brain and elucidate the existence of rules and features in the propagation path. Specifically, when the start site and the termination site of brain activity are clear, we aimed to clarify the nature of the propagation pathway such as whether the neural activity propagates in parallel or in series in the brain circuit. In the beginning, path estimation was performed on a small number of ROIs using fMRI measurement data (data obtained by measuring responses of the brain upon optogenetic activation of the hippocampus of an anesthetized mouse; Takata et al. 2015 PLoS One). As a result, we could estimate three paths as potential candidates.
