One *million* [/Dr. Evil voice] ARM processor cores are being hooked together to create a parallel computer called SpiNNaker that will try to simulate the human brain. Given that the human brain has about 100 billion neurons with 1,000 trillion connections between them all, this project is less than 1% of the way towards a full brain simulation. [url]

Growing a brain in a petri dish from rat neurons might be an interesting approach to building a brain de novo. So far, researchers have created a network of about 60 rat neurons which seem to be able to sustain activity for about 12 seconds. [url]

Folks from IBM are working on cognitive computing like the Systems of Neuromorphic Adaptive Plastic Scalable Electronics (SyNAPSE) project with some DARPA funding to re-create a billion artificial neurons. Trying to beat the power efficiency of the human brain isn't an easy task. [url]
