IBM and the Swiss Mind Brain Institute have created a project to "simulate an entire brain," which has a lovely Singularity ring to it, but as Mind Hacks points out, the fine print shows that the project is somewhat less ambitious than its billing would suggest.
Although impressive, this seems a far cry from simulating the 'entire brain', which would involve simulating 100 billion neurons and 100 trillion synapses in real-time.
This assumes, of course, there is a good enough understanding of how each neuron and synpase works – a science which is still very much in development.
