Detailed Description

Base class for all spiking neurons, i.e. spike emitting objects.

It maintains a list of emitted spikes. Outgoing synapses are granted to have access to this list to implement arbitrary long transmission delays. This is a memory efficient implementation since it would need more memory (for long delays)to store the spikes at each individual synapse.

Public Member Functions

• virtual ~SpikingNeuron ()

  The destructor clears the list of spikes.
  
  

• virtual void reset (void)

  Reset the SpikingNeuron.
  
  

• virtual int fired (void)

  This method should return 1 (0) if the spiking neuron fired a spike during the current time step.
  
  

• virtual int isRefractory (void)

  This method should return 1 (0) if the spiking neuron is in its absolute refractory period.
  
  

• int nSpikes (void)

  Return the number of spikes the object has emitted since t=0.
  
  

• double spikeTime (int i)

  Return the time of the i-th spike.
  
  

• void copySpikes (double *buffer)

  Copy the array of spike times to the given buffer.
  
  

• virtual int addIncoming (Advancable *S)

  Add an incoming synapse S.
  
  

• virtual int addOutgoing (Advancable *S)

  Add an outgoing synapse S and check whether S is derived from SpikingSynapse.
  
  

Protected Attributes

• bool hasFired

  Should be set to true (false) during an implementation of nextstate() if the neuron fires (does not fire).
  
  

Private Member Functions

• void propagateSpike (void)

  Notifies all spike destination about the spike at SimulationTime.
  
  

• void saveSpike (void)

  Add a spike at SimulationTime to the internal spike time list.
  
  

Private Attributes

• bool outSpike

  If true (false) all spike detinations will be informed about a spike at SimulationTime.
  
  

• double * Spikes

  An array of all spikes emitted.
  
  

• int nEmittedSpikes

  Number of spikes emited.
  
  

• int nSpikesAlloc

  Number of spikes which can currently be hold by the array.

• class SpikingInputNeuron
