_Lisource

A leaky integrator spiking node where the input current is calculated by the default operator for the object referenced by <source>. The source object is referenced and must be of type Particle. Noise can be added to the source by calling the default operator for the object referenced by <noise>. The noise object is referenced and must be of type Particle. If <force> is true, then the input current is set to the fixed value defined by <force-value>. The node operates differently if it is an input node. In this case it does not operate as a spiking node but as a store of the values that have been inputted over time. These values are stored in a seperate store <istore>. These values can be retrieved by calling the default operator for the node. They are typically used by the source objects associated with the non-input nodes when calculating the input currents.

Naming
    source         references the source object
    noise          references the noise object
    istore         references input store


Reverse References for Global Context
    owner          istore


Control
    istore         reset, dump, restore


Configuration
    source=<ref>   sets the source object (none)
    noise=<ref>    sets the noise object (none)
    force=<bool>   forces input to be specific value (false)
    force-value=<data>
                   sets the forced value (0.5)
    target=<data>  sets the target rate (50)
    tconstant=<data>
                   sets the time constant (0.01)
    rconstant=<data>
                   sets the R constant (4)


Source Points
    source         value of the source


Commands
    tune [target=<hz>] [sub=<data>]
        tune the node so that the target frequency is generated
          by a current of 0.5 and the node is not in the sub-threshold
          region for currents above <sub>
            target=<hz> the target rate 
            sub=<data> the sub-threshold current
