18th May 2001 Stochastic Resonance and finite resolutions Nhamoinesu Mtetwa, University of Stirling. Noise is often treated as irrelevant interference in systems like radios and telephones and engineers have always sought means to minimise it. Surprisingly, during the last two decades researchers have found that background noise is sometimes useful. Many physical systems, from electronic circuits to nerve cells, work better in the presence of certain types of noise. In this talk, I will discuss SR and the role that it plays in neuronal systems.
SR requires non-linear systems.
Neurons are also analogue and neuronal simulation emulates this. The simulation is usually done using floating-point arithmetic on conventional computers. No seminar this week because of examinations. 7th May 2001.
