The image demonstrates the design of an artificial brain built using a nano-brain reported in this issue of PNAS. Several molecular nano-brain are arranged in a way to work as powerful as our central nervous system. Numerical digits and alphabets float across the architecture demonstrating a matrix generated during a real-time operation similar to the Hollywood blockbuster The Matrix.

The most powerful computer known is the brain, and now scientists have designed a machine just a few molecules large that mimics how the brain works.
So far the device can simultaneously carry out 16 times more operations than a normal computer transistor. Researchers suggest the invention might eventually prove able to perform roughly 1,000 times more operations than a transistor.
This machine could not only serve as the foundation of a powerful computer, but also serve as the controlling element of complex gadgets such as microscopic doctors or factories, scientists added.
The device is made of a compound known as duroquinone. This molecule resembles a hexagonal plate with four cones linked to it, "like a small car," explained researcher Anirban Bandyopadhyay, an artificial intelligence and molecular electronics scientist at the National Institute for Materials Science at Tsukuba in Japan.
Duroquinone is less than a nanometer, or a billionth of a meter large. This makes it hundreds of times smaller than a wavelength of visible light.
The machine is made of 17 duroquinone molecules. One molecule sits at the center of a ring formed by the remaining 16. The entire invention sits on a surface of gold.
