Using today’s state of the art technology, it takes an AI-assisted researcher almost 50 hours to reconstruct a SINGLE neuron! At that pace, one researcher would need to devote the next 500 million years to neural mapping; no bathroom breaks allowed. (emphasis added) [Source]
...that information is processed on a massively parallel scale at relatively slow speeds; that memory and instruction signals are often seamlessly combined; and that continuous adaptation and self-organization of its neural networks play a crucial part in its function.

Most attempts at replicating a human brain involve simulating a very large number of neurons on a supercomputer; the neuromorphic approach, however, is quite different because it involves developing custom electronic circuits that simulate the neuron firing mechanisms in the actual brain and are similar to the brain in terms of size, speed and energy consumption.
Building blocks, or corelets, can be built using 256-neuron neuromorphic CPUs designed to do specific tasks. The “True North” library already has some 150 pre-designed corelets to do things like detect motion or image features, or even learn to play games. To play pong, for example, a layer of input neurons would be given information about the “ball” and “paddle” motions, an output layer would send paddle motion updates, and intermediate layers would perform some indeterminate processing.
