This class represents a neuron, which is able to fire spike events (thus it implements the NeuronOutput interface) and receive spikes indirectly via Synapses.

Constructor Summary | |
Neuron()
Default constructor with no arguments. |
Method Summary | |
void |
addInput(NeuronOutput sender)
This method adds another input to this Neuron, but the given input object does not have to be a Synpase, it just has to be some object implementing NeuronOutput. |
void |
addInputSynapse(Synapse synapse)
Adds a single synapse object to the list of input synapses. |
void |
addListenerVariable(mosaic.sim.kernel.variable.Variable v)
This implementation of VariableChangeListener.addListenerVariable does nothing. |
double |
computeTimeOfFire()
Computes the next fire time according to the current potential and threshold parameters. |
double |
getCurrentPotential()
Returns the current neuron potential. |
Synapse[] |
getInputSynapses()
Returns the list of currently registerd input synapses. |
Synapse |
getMasterSynapse()
Returns the master synapse object used for creating new synapse objects on the fly in the method addInput(). |
Potential |
getPotential()
Returns the potential object. |
int |
getPriority()
This implementation of VariableChangeListener.getPriority always returns 0. |
Threshold |
getThreshold()
Returns the threshold object. |
void |
processSimEvent(mosaic.sim.kernel.simevent.SimEvent e)
This method is called by the simulation framework when a time event occurs. |
void |
propertyChange(java.beans.PropertyChangeEvent e)
This implementation of VariableChangeListener.propertyChange does nothing. |
boolean |
removeInput(NeuronOutput sender)
Removes a NeuronOutput object from the input list of this neuron. |
boolean |
removeInputSynapse(Synapse synapse)
Removes a single synapse object from the list of input synapses. |
void |
removeListenerVariable(mosaic.sim.kernel.variable.Variable v)
This implementation of VariableChangeListener.removeListenerVariable does nothing. |
void |
reset()
This overrides the default behaviour of reset() by also resetting the associated potential and threshold objects. |
protected void |
scheduleNextFiring()
This method calculates the next firing time of this neuron (by using the method computeTimeOfFire) and schedules the neuron for activation at this time if a firing occurs or deactivates it if no firing will occur. |
void |
setInputSynapses(Synapse[] synapses)
Set the list of registered input synapses. |
void |
setMasterSynapse(Synapse master)
Sets the master synapse object used for creating new synapse objects on the fly in the method addInput(). |
void |
setPotential(Potential potential)
Sets the potential object. |
void |
setThreshold(Threshold threshold)
Sets the threshold object. |
void |
spikeEventFrom(Synapse sy)
This method is called by the synapses from the inputs list whenever they receive a spike event from their sender object. |
void |
variableChange(mosaic.sim.kernel.variable.VariableChangeEvent e)
This method is called by the simulation framework whenever a variable that this object is listening on changes. |
