Synchronization driven by correlated inputs

We consider how correlated inputs can ensure a group of neurons (the integr ate-and-fire model or the Hodgkin-Huxley model) to synchronize their activi ties. Without interactions, the shortest synchronization time occurs when t he coefficient of variation of efferent spike trains of single neuron is gr eater than 0.5. The application of synchronization driven by correlated inp uts to signal detection is also taken into account. (C) 2000 Elsevier Scien ce B.V. All rights reserved.
