Semantic Maps

Where are the concepts"anger" and "yellow" represented in the brain? A new Nature article reports some results on activation of brain regions in subjects listening to stories suggesting that there are specific regions in the brain in which such concepts are represented. Interestingly enough, there is a fair amount of consistency between individuals in where general concepts are represented, suggesting, but hardly proving, that there might be a fair amount of pre-wiring. The sample of individuals tested was neither large nor cross-cultural, though.
