Emergence of local synchronization in neuronal networks with adaptive couplings Synchronization in neuronal networks

Abstract

'Timothy Killingback' 'Jun Ma'] Local synchronization, both prolonged and transient, of oscillatory neuronal behavior in cortical networks plays a fundamental role in many aspects of perception and cognition. Here we study networks of Hindmarsh-Rose neurons with a new type of adaptive coupling, and show that these networks naturally produce both permanent and transient synchronization of local clusters of neurons. These deterministic systems exhibit complex dynamics with 1/f*η* power spectra, which appears to be a consequence of a novel form of self-organized criticality.
