Investigating Amplifying and Controlling Mechanisms for Random Events in Neural Systems

Abstract

Microscopic and individual events in the nervous system, such as single channel openings and individual action potentials, often drown in the summed activity of the surround. Yet, under certain circumstances such events can be amplified and have meso— and macroscopic effects. We use experimental as well as computational methods to investigate mechanisms by which neural systems can amplify weak signals and individual events, and control the system at a larger scale. By this multilevel approach we try specify the rules and constraints for the resulting state transitions.
