They’re in uncharted waters. Today, when it comes to mapping brains, we’re working with rudimentary cartography — but researchers armed with supercomputers are hoping they’ll wind up with something closer to Google Maps for the mind. First step: Chart the neural pathways information uses to flow through the brain, then monitor those roads for breakdowns. Add brain scans, genetics and behavioral data, and then scientists (and their computers) look for patterns. Meanwhile, one initiative’s uploaded 10 million gigabytes of data to the cloud so anyone can navigate mind seas for themselves.
