Researchers at USC have been sketching out a wiring diagram for rat brains (aka “brain connectome”) and have discovered that its structure is organized like the Internet. According to USC News, “Lead author Mihail Bota of USC Dornsife created the database from more than 16,000 reports of connections, which he weighted both on the strength of the connection and the reliability of the methodology used to discover it. The process took more than 4,000 hours to complete, yielding a database that is free and available.” The discovery is the results of the compilation and analysis of over 40 years’ worth of data detailing connections in rat brains.

The study was published in the Proceedings of the National Academy of Sciences on April 6, 2015.
