An optimal connection radius for long-range synchronization

We demonstrate, by means of computer simulations of a realistic cerebellar circuit model, the existence of an optimal axonal length (connection radius) for establishing long-range synchronous oscillations. Beyond the optimal axonal length, conduction delays hamper synchronization. The conduction delays also codetermine the oscillation frequency, making synchrony frequency-dependent. Large conduction delays and also doublet firing may stabilize low-frequency oscillations.
