Synchronous pacemaker
WebFeb 11, 2011 · Synchronous vs Asynchronous. Synchronous and asynchronous are two big words that seem intimidating but are quite simple. Synchronous simply means that all events are occurring in a certain time order that can be predicted. A certain event would always follow another and they can’t be interchanged. Asynchronous is the opposite of … WebLike pacemaker neurons in central pattern generators, subtypes of cortical cells fire bursts of spikes (brief clusters of spikes) rhythmically at preferred frequencies. Bursting neurons have the potential to serve as pacemakers for synchronous network oscillations, and bursts of spikes may underlie or enhance neuronal resonance.
