It’s like Google Maps for your cerebral cortex: A new interactive atlas, developed with the help of such unlikely tools as public radio podcasts and Wikipedia, purports to show which bits of your brain help you understand which types of concepts.
Hear a word relating to family, loss, or the passing of time — such as “wife,” “month,” or “remarried”— and a ridge called the right angular gyrus may be working overtime. Listening to your contractor talking about the design of your new front porch? Thank a pea-sized spot of brain behind your left ear.
The research on the “brain dictionary” has the hallmarks of a big scientific splash: Published on Wednesday in Nature, it’s accompanied by both a video and an interactive website where you can click your way from brain region to brain region, seeing what kinds of words are processed in each.
Yet neuroscientists aren’t uniformly impressed.
“This is technically very savvy,” said David Poeppel, a neuroscientist who studies language at New York University and who was not involved in the study. But he invoked an old metaphor to explain why he isn’t convinced by the analysis: He compared it to establishing a theory of how weather works by pointing a video camera out the window for 7 hours.
Indeed, among neuroscientists, the new “comprehensive atlas” of the cerebral cortex is almost as controversial as a historical atlas of the Middle East.
That’s because every word has a constellation of meanings and associations — and it’s hard for scientists to agree about how best to study them in the lab.
