Abstract

The recreation of the phenomenon of cyclic inhibition between two artificial nerve cells is discussed. 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
