Inside a 25,000 square foot room within Argonne National Laboratory one of the most formidable supercomputers in the world — Theta — is applying its incredible computing power to the largest batch of data ever recorded or analyzed. It’s information that researchers hope might one day contribute to our understanding of intelligence itself. And in this case, all that data fits inside the skull of a mouse. Theta is currently mapping the structures of mouse brains, using a data set that’s being gathered piecemeal by Narayanan “Bobby” Kasthuri, neuroscience researcher at Argonne National Laboratory and assistant professor in neurobiology at the University of Chicago.
