Neuroscience: Big Brain, Big Data
January 26, 2017
(Scientific American) – But brain mapping and DNA sequencing are different beasts. A single neuroimaging data set can measure in the terabytes — two to three orders of magnitude larger than a complete mammalian genome. Whereas geneticists know when they’ve finished decoding a stretch of DNA, brain mappers lack clear stopping points and wrestle with much richer sets of imaging and electrophysiological data — all the while wrangling over the best ways to collect, share and interpret them. As scientists develop tools to share and analyze ever-expanding neuroscience data sets, however, they are coming to a shared realization: cracking the brain requires a concerted effort.
