Class SYNNeuron

java.lang.Object

cnslab.cnsnetwork.SYNNeuron

All Implemented Interfaces:

Neuron, Serializable

public final class SYNNeuron
extends Object
implements Neuron, Serializable

Sync neuron (fake neuron, id is the last neuron index), used to synchronize between NetHosts, used to send half minimum synaptic delay time ticks, send buffered spikes
