Blue brain project.
The Blue Brain project uses IBM Blue Gene (TM) computers to simulate the entire brain. It differs from our efforts in that computer software and mathematical models are used to model the brain, while we are building hardware models of neurons, synapses and glial cells based on the biological model.

Dr. Eugene Izhikevich emulation of 100 billion point neurons
In October 2005 Dr. Eugene Izhikevich completed a 1 second simulation of 100 billion neurons on a Beowulf cluster of 27 computers that took 50 days to execute. This means that a desktop computer is at least 117 million times slower than the brain, even when using simplified neurons.

IBM’s simulation of a cat’s brain (and the controversy that followed)
In November 2009 IBM announced that they had successfully emulated a brain with the complexity of a cat’s brain. This sparked a heated discussion on what it exactly was that they simulated and how complex their model was.

Autonomous Learning Dynamic Artificial Neuron patent application published
The patent application paper of the Autonomous Learning Artificial Neuron is now online at the USPTO web site:
A hierarchical information processing system is disclosed having a plurality of artificial neurons, comprised of binary logic gates, and interconnected through a second plurality of dynamic artificial synapses, intended to simulate or extend the function of a biological nervous system. The system is capable of approximation, autonomous learning and strengthening of formerly learned input patterns. The system learns by simulated Synaptic Time Dependent Plasticity, commonly abbreviated to STDP
