Extracting the Multiscale Causal Backbone of Brain Dynamics

arXiv:2311.00118v2 Announce Type: replace
Abstract: The bulk of the research effort on brain connectivity revolves around statistical associations among brain regions, which do not directly relate to the causal mechanisms governing brain dynamics. Here we propose the multiscale causal backbone (MCB) of brain dynamics, shared by a set of individuals across multiple temporal scales, and devise a principled methodology to extract it.
Our approach leverages recent advances in multiscale causal structure learning and optimizes the trade-off between the model fit …
