ABSTRACT: One or more neurons can be perceived as an analog circuit in terms of their voltage-time characteristics, but at the block level, they can rather fulfill a logic function. This later approach is imposed by the neuron membrane behavior that always works between two voltage levels – the resting potential and the acting potential, easily associated to two binary states. These levels change when an appropriate combination of pulses trains appears on the neuron’s exciting and inhibiting input synapses. Being difficult to describe in all details the neuronal processes inside the human brain, this paper proposes some digital models able to mimic these biological processes. The first original element of this paper is the extension of the neuronal models, previously presented, from 0-order logic circuits to 1-order logic and 2-order logic circuits. The envelope signal shelters the pulses train that stimulate any neuron, and this envelope signal signature as the digital function represents an element of originality.KEYWORDS: Circuits; flip-flop; logic block; neurons; pulses trainRead full text (pdf)
