Dynamic transformation of pulse signals in neuronal systems

Kazantsev Viktor Borisovich, Institute of Applied Physics of the Russian Academy of Sciences

The dynamics of a neuron model with external pulse forcing in the form of bounded bursts is investigated. The processes of transformation of input pulse signal depending on the stimulus characteristics and neuron internal state are studied. A modified FitzHughNagumo system with a threshold manifold is used as the neuron model. It is found the neuron response provides selectivity on the number of acquired pulses (integrate-and-fire response) and on the inter-spike interval value (resonant response). The response signals are formed depending on the model parameters and represent either single pulses or pulse bursts with controllable number of constituent pulses.
