Abstract

In this study, the phenomenon of cyclic inhibition between two artificial nerve cells has been recreated. Implemented by means of postinhibitory rebound, it was achieved in a mutually inhibiting pair of identical nerve cell circuits, or Neuromimes. Each Neuromime is nominally self-excitatory, with a single inhibitory input, derived from the output of its counterpart. Postinhibitory rebound is accomplished by dynamically varying the synaptic weight of that inhibitory input. The Neuromime employed is a comprehensive VLSI-based circuit with a host of features attributable to biological nerve cells. It was fabricated in two-micron CMOS technology with a total chip area of 0.6 square millimeters, and requires only a few passive discrete components for support and adjustment. The circuit was designed as a prelude to the VLSI implementation of a biologically-based neuronal oscillator.
