When it comes to copying the real behaviour of synapses, two memristors are better than one, according to a new circuit design.

Since the 1970s, electronic engineers have known that there are four fundamental building blocks of electronic circuits: resistors, capacitors, inductors and memristors (essentially variable resistors with memory). Memristors, however, had an air of mythology about them until last year when a group of researchers at HP Labs in California announced they had discovered them for the first time.

Since then, numerous others have claimed to have played with memristance over the years (although none seem to have noticed what they were doing until now). In fact, it turns out that the synapses between neurons behave exactly like memristors. That raises the possibility that memristors can be connected together in a way that truly mimics the wiring of human brains.
