Member Function Documentation

advanceNeuron()

virtual void AllSpikingNeurons::advanceNeuron ( int index )

protectedpure virtual

Helper for advanceNeuron. Updates state of a single neuron.

Parameters

index

Index of the neuron to update.

Implemented in AllIZHNeurons, and AllLIFNeurons.

advanceVertices()

void AllSpikingNeurons::advanceVertices ( AllEdges & synapses, const EdgeIndexMap & edgeIndexMap )

virtual

Update internal state of the indexed Neuron (called by every simulation step). Notify outgoing synapses if neuron has fired.

Parameters

synapses	The Synapse list to search from.
edgeIndexMap	Reference to the EdgeIndexMap.

Implements AllVertices.

Definition at line 65 of file AllSpikingNeurons.cpp.

clearSpikeCounts()

void AllSpikingNeurons::clearSpikeCounts

(

)

Clear the spike counts out of all Neurons.

Definition at line 48 of file AllSpikingNeurons.cpp.

fire()

void AllSpikingNeurons::fire ( int index )

protectedvirtual

Initiates a firing of a neuron to connected neurons

Parameters

index

Index of the neuron to fire.

Fire the selected Neuron and calculate the result.

Parameters

index

Index of the Neuron to update.

Reimplemented in AllIZHNeurons, and AllLIFNeurons.

Definition at line 121 of file AllSpikingNeurons.cpp.

getSpikeHistory()

uint64_t AllSpikingNeurons::getSpikeHistory	(	int	index,
		int	offIndex )

Get the spike history of neuron[index] at the location offIndex. More specifically, retrieves the global simulation time step for the spike in question from the spike history record.

Parameters

index	Index of the neuron to get spike history.
offIndex	Offset of the history buffer to get from.

Get the spike history of neuron[index] at the location offIndex. More specifically, retrieves the global simulation time step for the spike in question from the spike history record.

Parameters

index	Index of the neuron to get spike history.
offIndex	Offset of the history buffer to get from. This indicates how many spikes in the past we are looking, so it must be a negative number (i.e., it is relative to the "current time", i.e., one location past the most recent spike). So, the most recent spike is offIndex = -1

registerHistoryVariables()

void AllSpikingNeurons::registerHistoryVariables ( )

overridevirtual

Helper function for recorder to register spike history variables for all neurons. Option 1: Register neuron information in vertexEvents_ one by one. Option 2: Register a vector of EventBuffer variables.

Register spike history variables for all neurons. Option 1: Register neuron information in vertexEvents_ one by one. Option 2: Register a vector of EventBuffer variables.

Implements AllVertices.

Definition at line 28 of file AllSpikingNeurons.cpp.

serialize()

template<class Archive >

void AllSpikingNeurons::serialize

(

Archive &

archive

)

Cereal serialization method.

Definition at line 144 of file AllSpikingNeurons.h.

setupVertices()

void AllSpikingNeurons::setupVertices ( )

overridevirtual

Setup the internal structure of the class (allocate memories).

Setup the internal structure of the class. Allocate memories to store all neurons' state.

Reimplemented from AllVertices.

Reimplemented in AllIFNeurons, and AllIZHNeurons.

Definition at line 14 of file AllSpikingNeurons.cpp.

Member Data Documentation

fAllowBackPropagation_
