IBM and EPFL Join Forces to Uncover the Secrets of Cognitive Intelligence

03 June 2005

Over the next two years scientists from both organizations will work together using the huge computational capacity of IBM's Blue Gene supercomputer to create a detailed model of the circuitry in the neocortex – the largest and most complex part of the human brain. By expanding the project to model other areas of the brain, scientists hope to eventually build an accurate, computer-based model of the entire brain.

By using a Blue Gene supercomputer to run experiments in real time, Markram anticipates a substantial acceleration in the pace of brain research."With an accurate computer-based model of the brain much of the pre-testing and planning normally required for a major experiment could be done ‘in silico' rather than in the laboratory. With certain simulations we anticipate that a full day's worth of wet lab research could be done in a matter of seconds on Blue Gene." The first phase of the project will be to make a software replica of a column of the neocortex. The neocortex constitutes about 85% of the human brain's total mass and is thought to be responsible for the cognitive functions of language, learning, memory and complex thought. An accurate replica of the neocortical column is the essential first step to simulating the whole brain and also will provide the link between genetic, molecular and cognitive levels of brain function. The second and subsequent phases will be to expand the simulation to include circuitry from other brain regions and eventually the whole brain. Elsewhere at EPFL, researchers will use Blue Gene to look at the use of plasmas as a possible method of energy production. Another team will use Blue Gene to research the folding of proteins and their role in the development of Creutzfeldt-Jacob (mad cow) and other diseases.
