Meet Spaun, The Most Complex Simulated Brain Ever

A screen capture from a simulation movie of Spaun in action shows the input image on the right. The output is drawn on the surface below Spaun's arm. Neuron activity is approximately mapped to relevant cortical areas and shown in color (red is high activity, blue is low). Chris Eliasmith has spent years trying to figure out the ingredients and precise recipe for building a brain. He even has a book coming out in February--called "How to Build A Brain"--describing gray matter, dendritic connections and other brainy anatomy.
