  We report experimental studies of synchronization phenomena in a pair of
biological neurons that interact through naturally occurring, electrical
coupling. When these neurons generate irregular bursts of spikes, the natural
coupling synchronizes slow oscillations of membrane potential, but not the fast
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.
