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.
