Power consumption is one of the biggest reasons that people aren't clamoring to build brainlike computers that exist beyond a lap. The artificial synapses that would need to be created would draw more power than the real things. Thankfully, using a realistic amount of energy is no longer something that is unattainable.

The human brain is capable of incredible things, especially if we use all of it, so the desire to have a computer that works more like the human brain isn’t for naught. For a long time, we have known that the brain has around 100 billion neurons and roughly 1 quadrillion (1 million billion) connections wiring these cells together.

Researchers have built nanowire synapses that use 1.23 femtojoules of power, which is a slight amount compared to the 10 femtojoules that a real neuron uses. They achieve that extremely low demand by taking two organic materials and wrapping them around each other, trapping ions, much like real nerve fibers would do.

Of course, there is a lot that has to be studied and done before doing this in a normal setting is practical. The scientists will want to shrink the nanowires down from roughly 200 nanometers thick to a few dozen nanometers.

They would also need to create new 3D printing techniques in order to create structures that imitate real brains more closely. Still, the concept of computers with the complexity of a brain is becoming more and more realistic. The team tells Scientific American that the application of a more realistic brain could help everything from self-driving cars to smarter robots.
