J Crayton Pruitt Department of Biomedical Engineering,University of Florida, Gainesville, FL 32611(Dated: June 3, 2008)We present two novel methods for performing logic operations. Our methods are based on usingthe time dimension for programming and data representation. The first method is based on varyingthe sampling moment in time of a neuronal action potential, and the second method is based on aneural delay system, where the generation of the action potential is delayed by specific time lengths,to be sampled at a fixed moment in time. Both methods are supported by explicit examples.
