Abstract

The results of a picture-pointing comprehension test show that agrammatic aphasics have difficulty understanding sentences in which the underlying semantic roles are marked by the order of noun phrases around a verbal element. Agrammatic patients performed poorly on reversible constructions involving spatial prepositions (e.g., “The square is above the circle”) and verbs (e.g., “The dancer applauds the clown”). These results have significance for the interpretation of the underlying disturbance in agrammatism—whether the deficit is syntactic or purely phonological.

Diffuse glioma-induced structural reorganization in close association with preexisting syntax-related networks
2023, Cortex
Glioma in the left frontal cortex has been reported to cause agrammatic comprehension and induce global functional connectivity alterations within the syntax-related networks. However, it remains unclear to what extent the structural reorganization is affected by preexisting syntax-related networks. We examined 28 patients with a diffuse glioma in the left hemisphere and 23 healthy participants. Syntactic abilities were assessed by a picture-sentence matching task with various sentence types. The lesion responsible for agrammatic comprehension was identified by region-of-interest-based lesion-symptom mapping (RLSM). Cortical structural alterations were examined by surface-based morphometry (SBM), in which the cortical thickness and fractal dimension were measured with three-dimensional magnetic resonance imaging (MRI). Fiber tracking on the human population-averaged diffusion MRI template was performed to examine whether the cortical structural alterations were associated with the syntax-related networks. The RLSM revealed associations between agrammatic comprehension and a glioma in the posterior limb of the left internal capsule. The SBM demonstrated that decreased cortical thickness and/or increased complexity of the right posterior insula were associated not only with agrammatic comprehension of the patients but also with the syntactic abilities of healthy participants. The fiber tracking revealed that the route between these two regions was anatomically integrated into the preexisting syntax-related networks previously identified. These results suggest a potential association between agrammatic comprehension in patients with diffuse glioma and structural variations in specific tracts and cortical regions, which may be closely related to the syntax-related networks.
Agrammatism in a usage-based theory of grammatical status: Impaired combinatorics, compensatory prioritization, or both?
2023, Journal of Neurolinguistics
This paper proposes an understanding of agrammatism from the perspective of a recent usage-based theory of grammatical status, the ProGram theory (Boye and Harder, 2012). According to this theory, grammatical elements have two central properties: they are by convention discursively secondary (i.e. attentional background) and dependent on combination with a host item. The paper first surveys studies of agrammatic speech which, based on or reconsidered in relation to the above-mentioned criteria, show that the usage-based theory makes correct predictions about the behaviour of linguistic elements in agrammatic speech. Subsequently, the paper outlines and discusses two hypotheses about the mechanism behind agrammatism that can be derived from each of the two central properties of grammatical items. According to the prominence hypothesis, agrammatism is due to insufficient overall processing resources; this leads to a prioritization of lexical over grammatical expressions because the latter, being discursively secondary, can be dispensed with for communicative purposes. According to the dependence hypothesis, agrammatism results from an impaired capacity for combining or unifying simple elements into complex wholes: This impairment affects grammatical elements in particular, because these are dependent on (combination with) host items.
Stable brain loci for the processing of complex syntax: A review of the current neuroimaging evidence
2021, Cortex
We conducted a retrospective review of fMRI studies of complex syntax, in order to study the stability of the neural bases of mechanisms engaged in syntactic processing. Our review set out rigorous selection criteria of studies which we discuss, including transparency and minimality of the contrasts between stimuli, and the presence of whole brain analyses corrected for multiple comparisons. Seventeen studies with 316 participants survived our sieve. We mapped the 65 resulting maxima onto JuBrain, a state-of-the-art cytoarchitectonic brain atlas (Amunts et al., 2020), and a sharp picture emerged: syntactic displacement operations (a k a MOVE) produce highly consistent results, activating left Broca's region across-the-board and unambiguously; to a somewhat lesser extent, maxima clustered in left posterior brain regions, including the STS/STG. The few studies of syntactic tree-building operations (a k a MERGE) produce a murkier picture regarding the involvement of the left IFG. We conclude that the extant data decisively point to the JuBrain-defined Broca's region as the main locus of complex receptive syntax in healthy people; the STS/STG also are involved, but to a lesser extent.
