Detailed Description

Base class for all analog neurons.

The delays of post-neuron synapses are implemented via a single queue (delayQueue) in the neuron itself to avoid storing the same data several times. A class derived from AnalogNeuron must store its membrane potential which is usually calculated during nextstate() in the variable Vm. The method output() of the neuron calls putInQueue() and then getFromQueue() for each of its post-neur synapses with the correct delay d of the corresponding synapse.

Public Attributes

• double Vm

  The current output (potential) of this neuron [readonly; units=V;].
  
  

• float Vresting

  The resting membrane voltage. [units=V; range=(-1,1);].
  
  

• double Inoise

  The noise of analog neurons [readwrite; units=A^2;].
  
  

Protected Attributes

• double VmOut

  The vlaue wich will actualle be propagated to the outgoing synapses.
  
  

Private Member Functions

• double getFromQueue (int delayIndex)

  Get previously stored value of the membrane voltage from delayQueue.
  
  

• void putInQueue (double theValue)

  Put membrane voltage into delayQueue.
  
  

Private Attributes

• Queue * delayQueue

  Queue to hold previous values of Vm; used to implement delays.

Member Function Documentation

void AnalogNeuron::putInQueue (  double    theValue )  [private]

Put membrane voltage into delayQueue. Attention: With every call to putInQueue a time step of dt is assumed. So be careful to call this only once during one time step step!

Member Data Documentation

double AnalogNeuron::Vm

The current output (potential) of this neuron [readonly; units=V;]. It is calculated during advance(), possibly overwritten in force(), and put into the queue during output().

double AnalogNeuron::VmOut [protected]

The vlaue wich will actualle be propagated to the outgoing synapses. The implementation of nextstate() should always set VmOut=Vm. However some Teacher may overwrite this by callinf force().
