It is possible to calculate how much computing power it would take to simulate a brain at a particular level. For simulations at the cellular level, there is for example this work by IBM researchers simulating a rat neocortical column: http://www.seedmagazine.com/news/2008/03/out_of_the_blue.php?page=all&p=y http://www.research.ibm.com/journal/rd/521/djurfeldt.pdf It's still a long way from simulating an entire brain and observing ratlike behaviour, but it does show that computational neuroscience is now beyond the philosopher's thought experiment stage. -- Stathis Papaioannou --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
