One thing I (almost) hate of some blog that report about scientific facts is that it’s difficult (or even impossible) try to figure out where data about this facts were found. I was talking with Alchemico about something of neurobiology, and after that he linked me this post “14 facts about brain”. One thing I’d like to check is for example:

“The brain is capable of storing 10 trillion bits of information about you and your life experiences.”

I’d like to know how can we know such a thing? How can we make this measurement? Where this data come from? 

It’s not that I have doubts about this fact is or is not true, but sometimes I’d like to go deeper on some subjects I read about, even if it’s only a list of funny (but interesting) things about brain.
