I think it's supposed to be "Brain" meaning "clever/genius" rather than the English usage implication of a disgusting fatty organ extracted from the skull. In other words, a transliteration problem. The English term comes from a word for the physical organ when considered as food (the original root means "that stuff inside the skull"). The usage to mean mental capability is much later (and probably originally derogatory, since it implied equivalence to a food animal's intellect).

"Wits" or "Smarts" would probably have been a choice that better reflected the idea the author had in mind, but at this point we're stuck with "Brain".
