What's Special About Human Brains?

11/26/2012 Georg Striedter, University of California Irvine "What's Special About Human Brains?" "Human brains are much larger than one would expect for primates of our body size. They also feature more neurons and a proportionately larger neocortex. Prefrontal cortex, in particular, is significantly larger in humans than in other species. Although these features make the human brain unique, most of them are in line with allometric expectations, meaning that they can be predicted from the large size of our brains. Thus, human brains are fairly typical primate brains; they just became unusually large. Nonetheless, there are good reasons to believe that the evolutionary expansion of the human brain, especially of prefrontal cortex, caused evolutionary changes in neural connectivity and function. Dr. Striedter will review some of the evidence supporting this idea and place it in the larger context of brain and behavioral evolution."

IBM unveils computer fed by 'electronic blood' brain-inspired computer

IBM unveils computer fed by 'electronic blood' IBM has unveiled a prototype of a new brain-inspired computer powered by what it calls "electronic blood". The firm says it is learning from nature by building computers fuelled and cooled by a liquid, like our minds, BBC News informs. The human brain packs phenomenal computing power into a tiny space and uses only 20 watts of energy - an efficiency IBM is keen to match. Its new "redox flow" system pumps an electrolyte "blood" through a computer, carrying power in and taking heat out. A very basic model was demonstrated this week at the technology giant's Zurich lab by Dr Patrick Ruch and Dr Bruno Michel. Their vision is that by 2060, a one petaflop computer that would fill half a football field today, will fit on your desktop. "We want to fit a supercomputer inside a sugarcube. To do that, we need a paradigm shift in electronics - we need to be motivated by our brain," says Michel. "The human brain is 10,000 times more dense and efficient than any computer today. "That's possible because it uses only one - extremely efficient - network of capillaries and blood vessels to transport heat and energy - all at the same time." IBM's brainiest computer to date is Watson, who famously trounced two champions of the US TV quiz show Jeopardy. The victory was hailed as a landmark for cognitive computing - machine had surpassed man. But the contest was unfair, says Michel. The brains of Ken Jennings and Brad Rutter ran on only 20 watts of energy. Whereas Watson needed 85,000 watts. Energy efficiency - not raw computing power - is the guiding principle for the next generation of computer chips, IBM believes. Our current 2D silicon chips, which for half a century have doubled in power through Moore's Law, are approaching a physical limit where they cannot shrink further without overheating. "The computer industry uses $30bn of energy and throws it out of the window. We're creating hot air for $30bn," says Michel. "99% of a computer's volume is devoted to cooling and powering. Only 1% is used to process information. And we think we've built a good computer?" "The brain uses 40% of its volume for functional performance - and only 10% for energy and cooling." Michel's vision is for a new "bionic" computing architecture, inspired by one of the laws of nature - allometric scaling - where an animal's metabolic power increases with its body size. An elephant, for example, weighs as much as a million mice. But it consumes 30 times less energy, and can perform a task even a million mice cannot accomplish. The same principle holds true in computing, says Michel, whose bionic vision has three core design features. The first is 3D architecture, with chips stacked high, and memory storage units interwoven with processors. "It's the difference between a low-rise building, where everything is spread out flat, and a high rise building. You shorten the connection distances," says Matthias Kaiserswerth, director of IBM Zurich. But there is a very good reason today's chips are gridiron pancakes - exposure to the air is critical to dissipate the intense heat generated by ever-smaller transistors. Piling chips on top of one another locks this heat inside - a major roadblock to 3D computing.
