Brain simulations are difficult because computers operate sequentially, with one or a few cores executing a preprogrammed set of instructions step-by-step, while the brain operates in parallel, with a multitude of highly interconnected neurons processing information distributed throughout the network. The computer can compensate for its lack of parallelism by executing instructions blazingly fast, but it pays a www lumia922.com steep cost in energy and time to shuttle far-flung data through its central processing unit—putting cortex-scale simulations out of reach. Our lab has built an affordable supercomputer to address this need—Neurogrid.
