Lab comes one step closer to building artificial human brain

In a laboratory in Switzerland, a group of neuroscientists is developing a mammalian brain -- in silicon. The researchers at the Ecole Polytechnique Fédérale de Lausanne (EPFL), in collaboration with IBM, have just completed the first phase of an ambitious project to reproduce a fully functioning brain on a supercomputer. By strange coincidence, their lab happens to lie on the same shores of Lake Geneva where Mary Shelley dreamt up her creation, Dr Frankenstein.

In June 2005, Henry Markram, director of the Blue Brain project, announced his intention to build a human brain using one of the most powerful supercomputers in the world. "The critics were unbelievable," recalls Markram. "Everybody thought we were crazy. Even the most eminent computational neuroscientists and theoreticians said the project would fail."

Some of Markram's peers said there simply wasn't enough data available to simulate a human brain. "There is no neuroscientist on the planet that has the authority to say we don't understand enough," says Markram. "We all know a tiny slice. Nobody even knows how much we know."
