Here is a presentation given by researcher Anders Sandberg for Google's Tech Talk series: "The idea of creating a faithful, one-to-one computer copy of a human brain has been a popular philosophical thought experiment and science fiction plot for decades. While computational neuroscience and systems biology are currently very far away from this goal, the trends towards large-scale simulation, industrialized neuroinformatics, new forms of microscopy and powerful computing clusters point in this direction and are enabling new forms of simulations of unprecendented scope. In this talk I will discuss current estimates of how close we are to achieving emulated brains, technological requirements, research challenges and some of the possible consequences." A little while back the Future of Humanity Institute published a roadmap to whole brain emulation. This topic is of interest to supporters of engineered longevity as a part of the very long term goal of incrementally replacing the vulnerable biology of the brain with something more robust and damage-resistant. Such as, for example, clusters of diamondoid nanomachines designed to emulate the functions of neurons.
