The paper contains the description of the main features of ion current pulsations in track devices. The conditions under which the pulsations arise are discussed. We describe different approaches that are used for interpretation of the effect of ion current pulsations. In particular the generalized model of current spikes in track devices is considered. To create this model a special modification of the classical molecular dynamics was developed. The results of application of this model coincide with the main experimental data concerning the ion current pulsations in track devices.
