A Method for Analyzing Community Dynamics in Temporal Networks Applied to Emotional Recollection in fMRI Data

Casey J. Wood, Western University

Abstract

Temporal networks exhibit evolving patterns of connectivity, making the study of community organization a critical component of their analysis. Communities within a network are characterized by entities displaying higher interconnectivity within the community than outside it. In temporal networks, these communities can change over time, requiring a more nuanced analysis compared to static networks. However, there is a scarcity of statistical tools designed to quantify and compare dynamic community organization in temporal networks. In this study, we introduce a measure tailored for this purpose. We use this measure to discriminate between functional brain networks in which subjects were tasked with recollecting different emotional states under fMRI.
