Detailed Description

Spike generation can be performed using spike generators. Spike generators are dummy-neurons that have their spikes specified externally either defined by a Poisson firing rate or via a spike injection mechanism. Spike generators can have post-synaptic connections with STDP and STP, but unlike Izhikevich neurons, they do not receive any pre-synaptic input. For more information on spike generators see Section Neuron groups: Spike generators in the Tutorial.

For fine-grained control over spike generation, individual spike times can be specified per neuron in each group. This is accomplished using a callback mechanism, which is called at each time step, to specify whether a neuron has fired or not.

Member Function Documentation

virtual unsigned int nextSpikeTime ( CARLsim *  s, int  grpId, int  i, unsigned int  currentTime, unsigned int  lastScheduledSpikeTime, unsigned int  endOfTimeSlice  )

pure virtual

Attention

The virtual method should never be called directly

Parameters

s	pointer to the simulator object
grpId	the group id
i	the neuron index in the group
currentTime	the current simluation time
lastScheduledSpikeTime	the last spike time which was scheduled
endOfTimeSlice	the end of the current scheduling time slice. Spike times after this will not be scheduled.

Implemented in SpikeGeneratorFromFile, SpikeGeneratorFromVector, PeriodicSpikeGenerator, InteractiveSpikeGenerator, and PrePostGroupSpikeGenerator.
