Building a Brain in a Supercomputer

Mental illness, memory, perception: they’re made of neurons and electric signals. Henry¬†Markram claims these mysteries of the mind can be solved — and soon. He is building a detailed, realistic computer model of the human brain and its one hundred trillion — that’s 100,000,000,000,000 — synapses.

Markram is the director of the Blue Brain Project at Ecole polytechnique federale de Lausanne (EPFL), one of two Swiss Federal Institutes of Technology located in Lausanne, Switzerland. Founded in 2005 by the Brain and Mind Institute at the EPFL, Blue Brain is a supercomputing project that to study the brain’s architectural and functional principles, and reverse engineer it in order to understand brain function and dysfunction. Blue Brain can model components of the mammalian brain in precise cellular detail and simulate neuronal activity in 3D. Soon Blue Brain will be able to simulate a whole rat brain in real time.
