Speaker: Henry D. I. Abarbanel Department of Physics and Marine Physical Laboratory, Scripps Institution of Oceanography, University of California, San Diego Title: Small Networks of Biological and Electronic Neurons We have studied, experimentally and theoretically, the membrane voltage activity of individual and small collections of neurons in a Central pattern Generator of lobster. Our nonlinear analysis of this activity will be presented, and we will show that only three to five degrees of freedom are expressed in these observations. I will describe "reduced" models of these neurons which capture just these degrees of freedom, and I will discuss our successful efforts in reproducing these models in low frequency, simple analog circuitry. We have successfully built "hybrid" circuits of electronic and biological neurons, and we have shown how one can repair damaged biological neural circuits using our electronic neurons. Some potential applications of the electronic/biological circuitry will be discussed.
