“…Nevertheless several studies, like the present one, have reported effects of syntactic manipulations in BA 45 or 47 (e.g., refs. 22,31,[41][42][43][44]. Most noteworthy is a recent study by Tyler et al (45) where the activations to grammatically coherent sentences without meaning were remarkably similar to those that we report here.…”

Linguistic analyses suggest that sentences are not mere strings of words but possess a hierarchical structure with constituents nested inside each other. We used functional magnetic resonance imaging (fMRI) to search for the cerebral mechanisms of this theoretical construct. We hypothesized that the neural assembly that encodes a constituent grows with its size, which can be approximately indexed by the number of words it encompasses. We therefore searched for brain regions where activation increased parametrically with the size of linguistic constituents, in response to a visual stream always comprising 12 written words or pseudowords. The results isolated a network of left-hemispheric regions that could be dissociated into two major subsets. Inferior frontal and posterior temporal regions showed constituent size effects regardless of whether actual content words were present or were replaced by pseudowords (jabberwocky stimuli). This observation suggests that these areas operate autonomously of other language areas and can extract abstract syntactic frames based on function words and morphological information alone. On the other hand, regions in the temporal pole, anterior superior temporal sulcus and temporo-parietal junction showed constituent size effect only in the presence of lexico-semantic information, suggesting that they may encode semantic constituents. In several inferior frontal and superior temporal regions, activation was delayed in response to the largest constituent structures, suggesting that nested linguistic structures take increasingly longer time to be computed and that these delays can be measured with fMRI.

“…This manipulation drastically reduces lexico-semantic content while keeping syntactic constituent structure intact, allowing to disentangle syntactic constituency effects from semantic co-herence effects (7,(20)(21)(22). It also introduces an important control for transition probabilities.…”

“…Specifically, IFG activation has been associated with semantic retrieval, lexical decisions, and the generation of semantic categories. Finally, neuroimaging studies have implicated the IFG in syntactic processing (e.g., Friederici et al, 2006;Kaan and Swaab, 2002;Roder et al, 2002). These classic areas are known to be involved in language processing; and, the IFG has been long associated with the semantic, phonological and syntactic aspects of language (e.g., Bedny et al, 2008;Kemeny et al, 2005;Rodd et al, 2010).…”

The role of the insula in speech and language processing

Lesion and neuroimaging studies indicate that the insula mediates motor aspects of speech production, specifically, articulatory control. Although it has direct connections to Broca's area, the canonical speech production region, the insula is also broadly connected with other speech and language centres, and may play a role in coordinating higher-order cognitive aspects of speech and language production. The extent of the insula's involvement in speech and language processing was assessed using the Activation Likelihood Estimate (ALE) method. Meta-analyses of 42 fMRI studies with healthy adults were performed, comparing insula activation during performance of language (expressive and receptive) and speech (production and perception) tasks. Both tasks activated bilateral anterior insulae. However, speech perception tasks preferentially activated the left dorsal mid-insula, whereas expressive language tasks activated left ventral mid-insula. Results suggest distinct regions of the mid-insula play different roles in speech and language processing.

“…The more complex syntactic structures are, the more difficult sentence comprehension generally becomes. Previous functional magnetic resonance imaging (fMRI) studies tested the effects of object-initial scrambled sentences in German and Hebrew, and reported enhanced activation in the left inferior frontal gyrus (IFG) and posterior superior/middle temporal gyrus (pSTG/MTG) [Ben-Shachar et al, 2004;Bornkessel et al, 2005;Fiebach et al, 2005;Rö der et al, 2002]. It is true that the sentences used in many of these studies make it difficult to know the cause of increased activation, since processing syntactically complex sentences is inevitably confounded by task difficulty, which may simply explain the increased activation, as indicated earlier.…”

It remains controversial whether the left inferior frontal gyrus subserves syntactic processing or short-term memory demands. Here we devised a novel picture-sentence matching task involving Japanese sentences with different structures to clearly contrast syntactic reanalysis processes. Using event-related functional magnetic resonance imaging (fMRI), activations under three main conditions were directly compared: a canonical/subject-initial active sentence (AS), a noncanonical/subject-initial passive sentence (PS), and a noncanonical/object-initial scrambled sentence (SS). We found that activation in the dorsal region of the left inferior frontal gyrus (dF3t) was enhanced more by the noncanonical processing under the PS and SS conditions than by the canonical processing under the AS condition, and this enhancement was independent of domain-general factors, such as general memory demands and task difficulty. Moreover, the left posterior superior/middle temporal gyrus (pSTG/ MTG) showed more enhanced responses to object-initial sentences under the SS condition than to subject-initial sentences under the AS and PS conditions, which were not significantly affected by task difficulty. Furthermore, activation in the left lateral premotor cortex (LPMC) increased under the AS, PS, and SS conditions, in that order. It is possible that task difficulty affects the left LPMC, but the three distinct activations patterns suggest that these frontal and temporal regions work in concert to process syntactic structures, with their respective contributions dynamically regulated by linguistic requirements.
