WHEN the "missing link of electronics" was finally built in 2008, it was the vindication of a 30-year-old prediction. Now it seems the so-called memristor can behave uncannily like the junctions between neurons in the brain.
A memristor is a device that, like a resistor, opposes the passage of current. But memristors also have a memory. The resistance of a memristor at any moment depends on the last voltage it experienced, so its behaviour can be used to recall past voltages.
