Simple Constraints for Zero-Lag Synchronous Oscillations under STDP

摘要

Zero-lag synchronous oscillations have been confirmed several times in biological experiments as well as successfully reproduced and simulated by theoreticians. But it has not been analyzed yet how synap-tic changes develop through STDP (spike timing-dependent plasticity) in a neural network of this type, and which physiological parameters have a qualitative influence on the synaptic strengths in long-term behavior. We analytically calculate these synaptic changes based on a simplified scheme which enables us to make conclusions about local and global connectivity patterns with the ability to produce zero-lag synchronous oscillations.
