Spike-timing-dependent plasticity in 'small world' networks
نویسندگان
چکیده
Biologically plausible excitatory networks develop a stable synchronized pattern of activity due to synaptic refractoriness (short term depression). The introduction of spike-timing-dependent plasticity (STDP) modifies the weights of synaptic connections in such a way that synchronization of neuronal activity is considerably weakened. By changing network connections to include long-distance connections according a power law distribution (’small world’ topology) we found that synchronization could be much better sustained, despite STDP influence.

Spike timing dependent plasticity: mechanisms, significance, and controversies
Long-term modification of synaptic strength is one of the basic mechanisms of memory formation and activity-dependent refinement of neural circuits. This idea was purposed by Hebb to provide a basis for the formation of a cell assembly. Repetitive correlated activity of pre-synaptic and post-synaptic neurons can induce long-lasting synaptic strength modification, the direction and extent of whi...

متن کاملRole of STDP in regulation of neural timing networks in human: a simulation study
Many physiological events require an accurate timing signal, usually generated by neural networks called central pattern generators (CPGs). On the other hand, properties of neurons and neural networks (e.g. time constants of neurons and weights of network connections) alter with time, resulting in gradual changes in timing of such networks. Recently, a synaptic weight adjustment mechanism has b...

متن کاملSmall-world structure induced by spike-timing-dependent plasticity in networks with critical dynamics
The small-world property in the context of complex networks implies structural benefits to the processes taking place within a network, such as optimal information transmission and robustness. In this paper, we study a model network of integrate-and-fire neurons that are subject to activitydependent synaptic plasticity. We find the learning rule that gives rise to a small-world structure when t...
