There is a paper in the current issue of Science, Paul J. Merolla, et al., "A million sparking-neuron integrated circuit with a scalable communication network and interface", Science, 2014 August 8,
available on-line at: http://www.sciencemag.org/content/345/6197/668 It reports on work by Pharmendra Modha and his colleagues (at both IBM and Cornell) under DARPA-sponsored Project SyNAPSE (Systems of Neuromorphic Adaptive Plastic Scalable Electronics). Crucially, True North appears to have very low power-consumption requirements, about 175,000 times less trhan those of the best supercomputer emulations of networks-of-neurons behavior. We in fact have something important here; the PR furor was appropriate. A shoe-box sized "brain", one that doesn't have the power requirements of New York's five boroughs, may now be in the womb of time.
