Hierarchical Bayesian inference for community detection and connectivity of functional brain networks

no code implementations18 Jan 2023 Lingbin Bian, Nizhuan Wang, Leonardo Novelli, Jonathan Keith, Adeel Razi

The method can robustly detect the group-level community structure of weighted functional networks that give rise to hidden brain states with an unknown number of communities and retain the variability of individual networks.

A mathematical perspective on edge-centric brain functional connectivity

1 code implementation20 Jun 2021 Leonardo Novelli, Adeel Razi

Edge time series are increasingly used in brain functional imaging to study the node functional connectivity (nFC) dynamics at the finest temporal resolution while avoiding sliding windows.

Deriving pairwise transfer entropy from network structure and motifs

2 code implementations7 Nov 2019 Leonardo Novelli, Fatihcan M. Atay, Jürgen Jost, Joseph T. Lizier

The pairwise (or bivariate) transfer entropy from a source to a target node in a network does not depend solely on the local source-target link weight, but on the wider network structure that the link is embedded in.
