One thing that’s kept engineers from copying the brain’s power efficiency and quirky computational skill is the lack of an electronic device that can, all on its own, act like a neuron. It would take a special kind of device to do that, one whose behavior is more complex than any yet created.
Suhas Kumar of Hewlett Packard Laboratories, R. Stanley Williams now at Texas A&M, and the late Stanford student Ziwen Wang have invented a device that meets those requirements. On its own, using a simple DC voltage as the input, the device outputs not just simple spikes, as some other devices can manage, but the whole array of neural activity—bursts of spikes, self-sustained oscillations, and other stuff that goes on in your brain.
This one took a lot of effort to achieve and there is still a lot of work to do to make a device that can be used on a large scale, but it sure does seem like a step in the right direction.

This is so cool. Genius approach. But how could the necessary temperature control be achieved for a brain's worth of these? Interesting if you could have an analogue PID type feedback loop. This might be a good avenue of investigation. Reliable, simple, power efficient...
