Abstract
In the modeling of neural systems, time is often treated as a sequencer, rather than as an expresser of information. We believe that this point of view is restricted, and that in biological neural systems, time is used throughout as one of the fundamental representational dimensions. We have developed this conviction partially because we model neural circuitry in analog VLSI, where time is a natural dimension to work with, and we believe there are deep similarities between the technology we use and the one nature has chosen for us.
