AnalogNeuron Class Reference #include <analogneuron.h> Inheritance diagram for AnalogNeuron: List of all members. Detailed Description Base class for all analog neurons. The delays of post-neuron synapses are implemented via a single queue (class Queue) 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. Classes struct Queue Queue for delaying the output of analog synapses. More... 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().
