Btw., the biological inspiration is now in a way reversed and a huge networked cluster of ARM nodes is currently used to simulate the brain in the SpiNNaker Project [1]. This project is headed by Steve Furber at Manchester University, one of the inventors of the ARM processor (with Sophie Wilson). With more than a million ARM9 cores and about 7 TB of distributed memory this is a bit of a different scale than a cluster of Raspberry Pis, though ;). SpiNNaker also reminds me of Dan Hillis' Connection Machine [2], but taking advantage of 40 years of progress with Moore's Law...
