Network Attractors driven by Time-Delay Plasticity

Abstract

We develop a framework for collective frequency selection and attractor formation by means of delay plasticity. Specifically, we consider adaptive axonal delays (AADs), motivated by activity-dependent myelination in the brain which regulates signal propagation speeds and thus communication delays. We demonstrate frequency selection and explosive network relaxation oscillations in systems of delay-coupled phase oscillators with AADs on brain connectivity data and fully coupled ring networks.
