“…Introduction. -Representing information and computing by means of systems composed of dynamical units has attracted huge attention in recent years in fields as diverse as cellular automata [1], lattices of coupled chaotic maps [2], chemical and neuronal diodes [3,4], patterned neuronal cultures [5] and chaotic neurons [6], or coupled non-linear systems [7,8]. The most promising methods are possibly those constructing Boolean ports with chaotic circuits (the so-called chaos computing [2,9,10]), or using adaptive mechanisms [11,12].…”
