Blue Brain Out-Thinks Its Critics
     


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.
