Subsections LifNeuronModel
A standard leaky-integrate-and-fire neuron model is implemented where the membrane potential Vm of a neuron is given by where is the membrane time constant, Rm is the membrane resistance, Isyn(t) is the current supplied by the synapses, Iinject is a non-specific background current and Inoise is a Gaussion random variable with zero mean and a given variance noise. At time t=0 Vm ist set to Vinit . If Vm exceeds the threshold voltage Vthresh it is reset to Vreset and hold there for the length Trefract of the absolute refractory period.
ImplementationThe exponential Euler method is used for numerical integration.
