blue brain
The Blue Brain Project is an attempt to create a synthetic brain by reverse-engineering the mammalian brain down to the molecular level. The aim of the project, founded in May 2005 by the Brain and Mind Institute of the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, is to study the brain's architectural and functional principles.
The project is headed by the founding director Henry Markram and co-directed by Felix Schürmann and Sean Hill. Using a Blue Gene supercomputer running Michael Hines'sNEURON software, the simulation does not consist simply of an artificial neural network, but involves a biologically realistic model of neurons. It is hoped that it will eventually shed light on the nature of consciousness.
There are a number of sub-projects, including the Cajal Blue Brain, coordinated by theSupercomputing and Visualization Center of Madrid (CeSViMa), and others run by universities and independent laboratories.
Goals
Neocortical column modelling[edit]
The initial goal of the project, completed in December 2006,[4] was the simulation of a rat neocortical column, which is considered by some researchers to be the smallest functional unit of the neocortex[5][6] (the part of the brain thought to be responsible for higher functions such as conscious thought). Such a column is about 2 mm tall, has a diameter of 0.5 mm and contains about 60,000neurons in humans; rat neocortical columns are very similar in structure but contain only 10,000 neurons (and 108 synapses). Between 1995 and 2005, Markram mapped the types of neurons and their connections in such a col
Progress[edit]
In November 2007,[7] the project reported the end of the first phase, delivering a data-driven process for creating, validating, and researching the neocortical column.
By 2005 the first single cellular model was completed. The first artificial cellular neocortical column of 10,000 cells was built by 2008. By July 2011 a cellular mesocircuit of 100 neocortical columns
