Recently, I posted a article about how much computational power it would take to emulate the human brain, and my calculations were off by a factor of 10. I've corrected my estimates and here are the updated sections:
Emulating the Human Brain
The Blue Brain Project has successfully simulated 1 cordical column on the Magerit super computer (100 TeraFLOPS), and human brain has an estimated 1,000,000 columns.
So with 5.2 ExaFlops, one could emulate 52,000 cordial columns. And that’s 1/20th of enough power to emulate a human brain.
To emulate the entire human brain you would need approximately 100 ExaFLOPs
That's a lot of FLOPS!
I chose the above estimation because many others rely on calculating how many operations per second the brain can processes, not how many computer calculations to emulate the brain. I.E. It takes many more computer computations to emulate a brain computation.

Conclusion
Henry Markham in his recent TED talk, thinks that a human brain could be emulated in 10 years.
I agree with his estimate, using Moore's law 10 years seems like an achievable goal.
