This is a model of a fully connected network with 10 neurons. The neurons are represented by leaky integrate and fire artificial spiking cells that are spontaneously active.

When isolated from all synaptic input, each cell fires at its own natural interspike interval (ISI), so the network is asynchronous (see raster plot above; horizontal axis in ms, vertical axis "cell number"). |
|
Synchrony can be achieved by making synaptic connections inhibitory (negative weights) and propagation delays > 0, although the slowest cells may miss some beats or drop out entirely. Notice the slight phase delay with increasing natural ISI. |
