To date we have simulated 515,980,000,000 neurons. The human brain has an estimated 100 billion neurons. For summary results click on the image link below.

Computing Information
The neural network simulator is an application that simulates neurons. Each downloaded work unit generates 500,000 biophysical neurons. Because the simulator is in an initial phase and we have very few cellular models implemented, we can only use it to test for simulations capacity. We have completed the first phase of the project, to simulate over 100 billion neurons. The second largest brain simulation has been done on a cluster of 27 machines, with 100 billion neurons simulated over a period of 50 days. While it was a very interesting experiment which pushed the frontier further on it was a partial simulation only, in the sense that many of the required components were not implemented due to hardware constraints.

The neurons were created, simulated and then destroyed in memory, without any data being stored. Based on their results the estimate for full brain simulations was calculated to be the year 2016; we would like to prove otherwise. From a practical point of view it didn't advance the knowledge further on and that's why we would like to continue along this line of thought and bridge these results with some practical data. The problem of storage and computing power is esential for large scale brain simulations because without them we can't plan and estimate these requirements. Without planning there is also no clear understanding as to what is needed in order to do that. As we advance with the simulation and more and more neurons get simulated, we should be able to make increasingly precise estimations on storage, number of computers required, duration, bandwidth and other factors. Regardless of the fact that at this stage our simulation is not precise and it lacks in many aspects, this is what we want to achieve with your help.

There is also the added benefit that once we will publish these results and the public at large would see that the capacity to simulate the entire brain is considerably higher than previously thought, a large stumbling block will be removed from the path of artificial intelligence.
