The role of negative links in brain networks.

Fabrizio Parente, Alfredo Colosimo


This paper provides a contribution to understand anti- (or negative) correlations between brain regions in fMRI
studies. We report about: 1) characterizing negative correlations under physiological conditions through a
careful analysis of records from healthy people; 2) reproducing a (homeostatic) equilibrium between different
brain areas by a Multi Agent System and a negative retroaction mechanism on a small network model.
