How to make a digital human brain

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.Friday night, a panel of experts at the World Science Festival here in New York parsed through challenges such undertakings pose for science and technology. The following are four of the hurdles to making a digital brain discussed...
