Edge functional connectivity

An application of Edge centric perspective to Neuroscience. The key idea is to define an edge time series by doing a “temporal unwrapping” of the Pearson correlation measure and use them to define edge-edge connectivity (correlation).

• Esfahlani2020high: High-amplitude co-fluctuations in cortical activity drive resting-state functional connectivity

• Rick Betzel‘s twitter thread: 1/ Thrilled to share two related pre-prints in which we introduce an edge-centric approach for modeling functional brain networks. Buckle in, this thread is going to be longer than normal.

Novelli2022mathematical argues that the results using eFC can be derived from the nFC with a simple null hypothesis.
