" If you want big improvements, she said, chew gum. Gum? Sure enough, chewing gum has been shown to improve a person's immediate recall of learned words by some 24 percent. Long-term recall improves by a larger 36 percent. To get the benefit, you actually have to chew gum as you are studying; for some reason you can't merely move your jaw up and down. I also discovered that drinking sage tea increases one's recall of words modestly, as does the odor of rosemary. Something as mundane as coffee provides a benefit, too. Drinking two cups of coffee increases neuronal activity in the frontal lobe, where working memory is controlled, and in the anterior cingulum, where attention is controlled. "

" The fact that early languages, no matter how many there are, utilize the same streams implies that the brain doesn't have a native language. The brain can only reflect the fact that a set of neural circuits was built and activated for a certain period of time. Nor does the brain care if those neural circuits map onto things that the rest of the world calls languages or dialects. It really cares only about what activates those circuits. Thus, the brain patters that typify language use across skill levels can be mapped.
Brain imaging technology monitors the intensity of oxygen use around the brain - higher oxygen use represents higher energy use by cells burning glucose. The deeply engrained language circuits will create dim MRI images, because they are working efficiently, requiring less glucose overall. More recently acquired languages, as well as those used less frequently, would make neural circuits shine more brightly, because they require more brain cells, thus more glucose. "

" Knowing I might never visit the archives again, I had hit on a solution to get at Mezzofanti's proficiency: I'd count the letters he received in each language. If he got many, he must have been writing a lot, and that, maybe, pointed to a great deal of practice, then to a high degree of proficiency. It was a fair social science hypothesis.
I told Pasti about my plan. The librarian smirked at me. "You're a positivist, I think," he said. A positivist is someone who believes you can get at truths only through what can be counted, measured, and observed. I was shocked - I've been called names before, but never that. "
