From today's Numlock News:
Not Exactly Rocket Science
Scientists have just published the highest resolution image ever of a small piece of the human brain just 1 cubic millimeter in size. The dataset this single square millimeter of mind produced is 1,400 terabytes in size, and if the full human brain were to be reconstructed in a similar fashion, the resulting dataset would be a zettabyte, a billion terabytes, or about a year's worth of all digital content produced. The rendered image shows a vast and interconnected web of neurons, colored by size and ranging from 15 to 30 micrometers across. A human brain has 86 billion of those neurons, with some 100 trillion connections. It's kind of crazy that most of them are used to replay embarrassing events from your life right as you're trying to fall asleep, but them's the breaks.
