In the most recent issue of Nature Neuroscience , David Poeppel and his colleagues have published a paper (non-paywalled PDF) detailing research that supports Noam Chomsky's hypothesis that we possess an "internal grammar" that allows us to comprehend even nonsensical phrases. This hypothesis is rejected by most neuroscientists and psychologists, who contend that comprehension of language arises rather from the brain making statistical inferences based on words and sound cues.
From phys.org's report on the research:

"One of the foundational elements of Chomsky's work is that we have a grammar in our head, which underlies our processing of language," explains David Poeppel, the study's senior researcher and a professor in New York University's Department of Psychology. "Our neurophysiological findings support this theory: we make sense of strings of words because our brains combine words into constituents in a hierarchical manner—a process that reflects an 'internal grammar' mechanism."

...the researchers explored whether and how linguistic units are represented in the brain during speech comprehension.

To do so, Poeppel, who is also director of the Max Planck Institute for Empirical Aesthetics in Frankfurt, and his colleagues conducted a series of experiments using magnetoencephalography (MEG), which allows measurements of the tiny magnetic fields generated by brain activity, and electrocorticography (ECoG), a clinical technique used to measure brain activity in patients being monitored for neurosurgery.

...Their results showed that the subjects' brains distinctly tracked three components of the phrases they heard, reflecting a hierarchy in our neural processing of linguistic structures: words, phrases, and then sentences—at the same time.

"Because we went to great lengths to design experimental conditions that control for statistical or sound cue contributions to processing, our findings show that we must use the grammar in our head," explains Poeppel. "Our brains lock onto every word before working to comprehend phrases and sentences. The dynamics reveal that we undergo a grammar-based construction in the processing of language."

This is a controversial conclusion from the perspective of current research, the researchers note, because the notion of abstract, hierarchical, grammar-based structure building is rather unpopular.

    How many different gramatically-unrelated languages was this performed in? I'm guessing 1. The fact that it had the audacity to mention "words", "phrases", and "sentences" immediately tells me that they didn't look at any of the agglutinative Aleutian languages which don't even have those as separate concepts.

    I bet the brain reacts differently when presented with one name, a short list of unfamiliar names, and a long list of familiar names. That doesn't mean there's some deep "name list" grammar in our brains, that's just relying on different layers of and different operations on a memory heirarchy.

    And even if brains do appear to be treating words, phrases, and sentences differently, that could simply be learnt behaviour, rather than any deep structure. Those who can juggle juggle 3 cold potatoes differently from how they juggle 1 hot potato, that doesn't mean there's deep potato-juggling structure in the brain.

    The greatest weakness of computer nerds (of which I'm one) is to think that Chomsky made great contributions to linguistics - he didn't. He should be lauded for his outspoken stance on political matters, not for any earth-shattering linguistic breakthroughs. Sure, his stuff was interesting, as was Da Vinci's helicopter, but that doesn't mean it will fly.

      The study's subjects listened to sentences in both English and Mandarin Chinese in which the hierarchical structure between words, phrases, and sentences was dissociated from intonational speech cues—the rise and fall of the voice—as well as statistical word cues.

        Both English and Mandarin Chinese are fairly isolating languages, with one or occasionally two morphemes per word. As FatPhil points out, a polysynthetic Eskimo or Aleutian language would have a different underlying structure of what makes a "word".

          Dude, thanks for the support!

          2 languages? 2 freaking languages? It's claiming to say something about *all* human (at least all humans which have a human brain, which is probably all of them) language processing. Which makes this study a *joke*. I'm happy to keep my "linguist who thinks Chomsky contributed very little that is productive to the field" hat on even though I'm a computer nerd too, and quite closely politically aligned to him.

      There is some evidence that babies have innate communication abilities (beyond just crying). If one supposes that all communication involves some sort of grammar or structure, then the idea is no so far-fetched. http://news.byu.edu/archive13-jun-babytalk.aspx [byu.edu]

        then the idea is no so far-fetched

        It wasn't an idea, it was a hypothesis (the grammatically-structured baby communication).
        An idea would answer to "how can one verify the hypothesis" for the case in which the subjects don't (yet) use words.

    Parser doesn't necessarily imply grammar. No firm ground for neither camp to make a strong stance, and that is as expected in psycho/neuro whatchamacallit.

      Holy crap. Look at figure 1C. The "MEG-derived cortical response spectrum for Chinese listeners and materials" has peaks at 1 HZ, 2 HZ, 3 Hz, 4Hz. Why would the brain be oscillating at whole number frequencies (based on an arbitrary length of time) like this? That looks like either an artifact or something very interesting. Is this normal in MEG studies?

        It is very easy to understand the peaks in figure 1c if you look at figures 1b and 1a: the materials were presented to listeners at a base rate of 4 Hz. FTFA:

        Are the responses at the phrasal and sentential rates indeed separate neural indices of processing at distinct linguistic levels or are they merely sub-harmonics of the syllabic rate response, generated by intrinsic cortical dynamical properties? We address this question by manipulating different levels of linguistic structure in the input [ snip ]

        We expect that the neural responses to the long verb phrase to be tagged at 1 Hz, whereas the neural responses to the monosyllabic verb and the three-syllable noun phrase will present as harmonics of 1 Hz. Consistent with our hypothesis, cortical dynamics emerged at one-fourth of the syllabic rate, whereas the response at half of the syllabic rate is no longer detectable.

        Actually, that is from the same page as the figure. I propose a new mod, DNRTFA (-1).

    Of course we have a neural substrate that's particularly apt at understanding language, and of course the MEG will show results of phrase ending. There's been evidence for this since the 70s and it's unrelated to Internal or Universal Grammar. The Articificial Markovian Sentences prove nothing: the grammar is not "learned" the way the other two languages, English and Chinese, were learned by their native speakers.
