[Scientists have produced a map of the brain](http://news.illinois.edu/news/12/0410braininjury_AronBarbey.html). The lead researcher notes that they think they have found where particular mental activities occur: that is, their goal was to map, in a one-to-one fashion, links between an ability and a region of the brain. They used a large group of Vietnam veterans with localized brain injuries, who also suffered particular gaps in cognitive function:

> Scientists report that they have mapped the physical architecture of intelligence in the brain. Theirs is one of the largest and most comprehensive analyses so far of the brain structures vital to general intelligence and to specific aspects of intellectual functioning, such as verbal comprehension and working memory. Their study, published in _Brain: A Journal of Neurology_, is unique in that it enlisted an extraordinary pool of volunteer participants: 182 Vietnam veterans with highly localized brain damage from penetrating head injuries.

I need to read [the article](http://brain.oxfordjournals.org/content/early/2012/03/05/brain.aws021.short?rss=1). The summary from the University of Illinois press release defines mental function rather loosely, e.g. “general intelligence.” (This, however, may be in fact a rather precise term within neurology, and thus I am only revealing my ignorance.)
