Connectomics aims to map the atlas of the brain
This week's Economist carried a story on the wiring diagram of the brain. It is worth reading.
"The result of all this effort, it is hoped, will be precise circuit-diagrams of brains. The first brains to be mapped will probably have belonged to mice. Besides being cheap and disposable, a mouse brain weighs half a gram and packs a mere 16m neurons. Human brains (1.4kg and 100 billion neurons) will come later, when all the wrinkles have been ironed out in rodents, and proper methods devised to analyse the results. But come they will. And when they do, the most complicated object in the known universe will begin to give up the secrets of how it really works."
