Brain Activity

This comes from an article where scientists are culturing neurons and recording and analysing the signals they generate. It’s a pretty incredible statistic:

In the meantime, his virtual-rat project faces a number of technical challenges, such as how exactly he’s going to pull patterns out of data streaming in from his dish of neurons at 2.3 Mbytes per second, per channel – enough to max out a multigig hard disk in one afternoon. If you were using the same technology to record input from every neuron in a human brain, you’d get 150 million Gbytes of data per minute – enough to fill a 194-mile-high stack of CD-ROMs in 60 seconds.

That’s 1 Exabyte every 400 seconds (6.5 minutes).
