Summary:
The way in which brain structure constrains the brain’s functional activity is one of the critical questions in the field of neuroscience. In this research, first, we reconstructed causal interactions among neurons from the hippocampus using spike trains, which were recorded on a 512 electrode array system. Next, we separated the network structures by using several community detection analysis techniques, and extracted the subgroups of neurons communicating with each other. As a result, we could compare the estimated separation line and the structural dividing lines among Dentate Gyrus (DG), CA3, CA1 hippocampal regions. In this paper, we show the primitive result. In the main conference, I will also talk about the advanced result and discuss how it relates to the concept of ?euronal Avalanches [1].
