Abstract

Recently discrete dynamical systems, maps, have been also used as valid phenomenological neuron models, and are able to furnish an advantageous alternative to continuous dynamical systems for the modelling of the spiking behavior of single neurons and of neuronal networks as well. Periodic and chaotic spiking, phasic and tonic bursting, subthreshold oscillations and many more specific features of the activity of real neurons can be reproduced by maps with a minimum of analytical complexity. As an external stimulation is applied to the neuron, its response can be of two different natures: periodic or erratic. We present a simple method of control that allows to choose one of the possible responses when the perturbation is periodic. The phase difference between the periodical driving and the control plays a decisive role.
