Brain On a Chip and other related mind technology

A well-covered recent article in MIT's Technology Review reports that a team of European scientists may have taken the first steps in creating a silicon chip designed to function like a human brain.

The human cortex has about 22 billion neurons and 220 trillion synapses. A supercomputer capable of running a software simulation of the human brain doesn't yet exist. Researchers estimate that it would require at least a machine with a computational capacity of 36.8 petaflops (a petaflop is a...
