Paper Abstract

Homoclinic spike trains have been intensively investigated for single mode CO2 lasers; however, their occurrence has a more general significance insofar as this scenario fits the main aspects of action potentials in neurons. Stabilizing homoclinic trains has therefore a relevance for neural communication and synchronization, which seems to be the universal time code for perceptions. The core dynamics of homoclinic chaos is represented by the passage through a saddle point, in which neighborhood the system susceptibility (response to an external perturbation) is very high and hence it is very easy to apply a control. A few aspects of regularization of homoclinic chaos are covered, such as, synchronization by an external pace-maker, DSS (delayed self-synchronization), bursting, and NIS (noise induced synchronization). Such a general scenario is compared with specific neurodynamic models; moreover its impact on communicating with chaos is discussed. (Summary only available)
