Detailed Documentation

Izhikevich neuron with variable parameters izhikevich2003simple.

This is the same model as Izhikevich but parameters are defined as “variables” in order to allow users to provide individual values for each individual neuron instead of fixed values for all neurons across the population.

Accordingly, the model has the Variables:

• V - Membrane potential
• U - Membrane recovery variable
• a - time scale of U
• b - sensitivity of U
• c - after-spike reset value of V
• d - after-spike reset value of U

and no parameters.

Methods

virtual StringVec getParamNames() const

Gets names of of (independent) model parameters.

virtual VarVec getVars() const

Gets names and types (as strings) of model variables.
