Virtual Brain Networks

How do you build a brain, one neuron at a time? The Blue Brain project spent 10 years dissecting rat brains and recording the activity on a neuronal level, seeking to reproduce the neocortical column in microcircuit. It seems that if you get enough neurons together, simulated or otherwise, a sort of sync happens, spontaneously causing neurons to fire in rhythm. The stated goal: build a human brain. It is very unlikely that we will be able to simulate the human brain at the molecular level detail with even the most advanced form of the current technology. However, there are other directions to solve this problem. We are going to move to molecular level modeling of a NCC (Neocortical Column). This software version could in principal be converted into a hardware version - a molecular level NCC chip - and then we can duplicate as many of them as we want. What about a distributed model? Use the worlds' computers for a very slow Treant brain, years between words. Here's.. what... a... fake brain looks like. DARPA has declined to continue investing in companion programs like BICA, so my dream of intelligent killbots must wait for stupid killbots to become obsolete and destroyed by their superior killbot models. Cognitive computing has long been tantalizingly theoretical and littered with utter failures. Why is a piece of meat so difficult? Maybe it's more like music, "It's not the notes you play, it's the notes you leave out".
