Stabilizing synchrony by inhomogeneity
We show that for two weakly coupled identical neuronal oscillators with strictly positive phase resetting curve, isochronous synchrony can only be seen in the absence of noise and an arbitrarily weak noise can destroy entrainment and generate intermittent phase slips. Small inhomogeneity-mismatch in the intrinsic firing rate of the neurons-can stabilize the phase locking and lead to more precis...
متن کاملSelf-stabilizing Virtual Synchrony
Virtual synchrony (VS) is an important abstraction that is proven to be extremely useful when implemented over asynchronous, typically large, message-passing distributed systems. Fault tolerant design is critical for the success of such implementations since large distributed systems can be highly available as long as they do not depend on the full operational status of every system participant...

متن کاملBreaking synchrony by heterogeneity in complex networks.
For networks of pulse-coupled oscillators with complex connectivity, we demonstrate that in the presence of coupling heterogeneity precisely timed periodic firing patterns replace the state of global synchrony that exists in homogenous networks only. With increasing disorder, these firing patterns persist until a critical temporal extent is reached that is of the order of the interaction delay....
متن کاملEnhancing Synchrony with Plasticity
In the previous lab, we explored spike timing-dependent plasticity (STDP) as well as its role in achieving precise timing in a feedforward network. In this lab, we study how STDP compensates for neuronal variations and input noise in a network of recurrently connected neurons. In this prelab, we consider how a recurrent network with STDP synapses and (sinusoidal) global theta inhibition (8.75Hz...
