I pulled that out of my memory not off a website.

When Googling for the answer as to how fast the human brain works, you'll get a range of values. As it happens the first response agreed:

FLOPS MIPS Watts and the Human Brain

Furthermore, there is no real consensus regarding the computational power of the human brain. Some estimates suggest that it is capable of 10¹⁷ FLOPS, or a 100 petaflops.
