Yes! And sometimes you're just sitting there quietly among other people when it hits you and your head jerks up and you exclaim "OH! It's such and such!" and people look at you. "She shouts random things. .."
When you get a sense of your future relations with a person about 30 seconds after meeting them. This is definitely magnified and defined (in a black or white sense) if the Ni user has a active use of Fi. *shutters*

Actually, I've once read a chic article somewhere on the internet correlating MBTI functions and hemisphericity. It put Se, Ne, Ti, Fi as right brained, and other four as left brained... according to this theory all perceivers are indeed right brained.
None of the type functions can be truly be said to be located in a specific part of the brain. However, each function draws upon certain brain functions which are known to be located in a particaular hemisphere or region. Introverted perceiving functions (Si and Ni) are intimately associated with the language centres of the brain, which are located in the left hemisphere. Likewise, extraverted judging functions are associated with the brain's executive control centres, which are located in the front of the left hemisphere. For this reason, All J-types are said to be more left-brained than P-types, who tend to favour right-brain processes. For more information, check out this article:
i had limited patience with reading beebe and dont remember much from braintypes, but to me it seems, that they assume the functions and the function order to be correct and then they map them to the brain. to put it differently, they map for example the introverted dichotomy judger (as he is live and kicking) to his brain according to how the brain could explain his actual behavior in terms other than functions, and later map the functions that they contribute to the judger (Pi+Je) in an equal manner. so they would say, that the brain tells something about what the functions are, after mapping them arbitrary. if they had mapped the functions (letters) differently, the brain would lead to different assumptions about the functions/letters. so a lot of that is thesis and not much of it is proof for any thesis. the bottom line is only, that there is some potential compatibility between the idea of 8 functions and the brain, meaning that you can invent plenty of compatible theses. braintypes.com does not work with functions as well, as far as i remember, but only with dichotomies.
