Mapping brain activity at scale with cluster computing

O'Reilly published and then deleted a post by Jeremy Freeman describing this article. I'm not sure why it went down, but it was fascinating, as it described how scientists are mapping the hundreds of thousands of neurons in the brain of a larval zebrafish. Part of the focus (and the focus of the original scientific article) was on the need for large clusters of computers to perform what essentially amounts to big data analysis. But Freeman also comments (in the O'Reilly article) about the results of the analysis. "In most artificial networks, each node does essentially the same kind of thing, whereas everywhere we look in the brain we see diversity. There are hundreds or thousands of different kinds of neurons, with diverse morphologies, functions, patterns of connectivity, and forms of communication." I'm not sure if this link will continue to work but I've saved the articles for future reference.
