Synchronous behavior of two coupled biological neurons

We report experimental studies of synchronization phenomena in a pair of bi ological neurons that interact through naturally occurring, electrical coup ling. When these neurons generate irregular bursts of spikes, the natural c oupling synchronizes slow oscillations of membrane potential, but not the f ast spikes. By adding artificial electrical coupling we studied transitions between synchrony and asynchrony in both slow oscillations and fast spikes . We discuss the dynamics of bursting and synchronization in living neurons with distributed functional morphology.
