We first posted about the Blue Brain Project back in 2005. The idea was to use massive computing power to accurately simulate enough biological neurons to reproduce part of a mammal brain's functionality. The project was widely criticized as "ridiculous". With the recent successful conclusion of the project's first phase, critics who claimed the project was "bound to fail" have been effectively proven wrong. The current system accurately reproduces the neocortical column of a two-week old rat, composed of 10,000 neurons with 30 types of ion channels and 30 million interconnections. Surprisingly, at least to the critics, the computational structure does what the biological structure does even at the level of individual neurons. But don't get too excited yet, the researchers believe reproducing an entire Human brain would require processing over 500 petabytes of data. A computer like that is 10 years away if Moore's law continues to hold. To build it using today's processors would result in a brain that costs $3 billion per year in electricity to operate (versus our meat brains that need only 25 watts!) Meanwhile, SEED magazine has an article about the recent achievements of the Blue Brain and the conscious entities blog has written some thoughtful commentary about the project.
