4 Hurdles to Making a Digital Human Brain


NEW YORK — Futurists warn of a technological singularity on the not-too-distant horizon when artificial intelligence will equal and eventually surpass human intelligence. But before engineers can make a machine that truly mimics a human mind, scientists still have a long way to go in modeling the brain's 100 billion neurons and their 100 trillion connections.

Already in Europe, neuroscientist Henry Markram and his team established the controversial but ambitious Human Brain Project that's seeking to build a virtual brain from scratch. Earlier this year, U.S. President Barack Obama announced that millions of federal dollars will be put toward efforts to map the brain's activity through the Brain Research through Advancing Innovative Neurotechnologies, or BRAIN, Initiative.
