Mechanisms underlying syntactic comprehension deficits in vascular aphasia: new evidence from self-paced listening

The results point to more than one mechanism underlying syntactic comprehension disorders both across and within pwa, suggesting that a previously unidentified disturbance limiting the duration of parsing and interpretation may lead to structure-specific deficits in pwa.

Syntax-sensitive regions of Broca’s area and the posterior temporal lobe are differentially recruited by production and perception

An fMRI study designed to test the hypothesis that language-selective subregions of Broca’s area play a role in syntax driven by the demands of production, finds robust significant interactions of comprehension and production between these two regions at the syntactic level, for both sets of language- selective ROIs.

The Auditory Comprehension of Unaccusative Verbs in Aphasia

Some persons with aphasia, particularly those diagnosed with a Broca’s aphasia, exhibit a delayed time course of lexical activation in canonically ordered S-V-O sentences (Ferrill et al., 2012) and

The time-course of lexical activation during sentence comprehension in people with aphasia.

Evidence supports the hypothesis that the delay in lexical activation feeds syntactic processing too slowly, contributing to comprehension deficits in people with agrammatic aphasia.

Neural Correlates of Processing Passive Sentences

Previous research has shown that comprehension of complex sentences involving wh-movement (e.g., object-relative clauses) elicits activation in the left inferior frontal gyrus (IFG) and left

The curious case of processing unaccusative verbs in aphasia

Support is provided that IWBA do not evince a delayed time course of lexical reactivation for unaccusative verbs compared to neurologically unimpaired individuals.

Neural Aspects of Sentence Comprehension: Syntactic Complexity, Reversibility, and Reanalysis

The interaction of syntactic complexity and semantic reversibility in a functional magnetic resonance imaging study of sentence–picture matching confirmed a unique role for Broca's area in syntactic processing, and suggested that full syntactic parsing may be a nonautomatic process applied as needed.



Neurological Distribution of Processing Resources Underlying Language Comprehension

Using a cross-modal lexical priming technique, an on-line examination of the ability of aphasic patients to construct syntactically licensed dependencies in real time indicates that the cerebral tissue implicated in Wernicke's aphasia is not crucial for recovering syntactic licensed structural dependencies, while that implicated in Broca's aahsia is.

Syntactic priming in broca's aphasics: Evidence for slow activation

Abstract Recently, several investigators have suggested that the parsing system of Broca's aphasics is affected by a resource limitation which could involve (1) a reduction in the size of a syntactic

Broca's Aphasia Is Associated with a Single Pattern of Comprehension Performance: A Reply

In 1999, a survey of comprehension scores for Broca’s patients conventionally selected via the Boston Diagnostic Aphasia Exam and other like instruments was published and the picture that emerged was very clear: The Broca's patients as a group performed significantly above chance level in their comprehension of structures without displaced constituents.

Semantic Operations in Aphasic Comprehension: Implications for the Cortical Organization of Language

Results indicate that, whereas Broca's patients have little or no trouble understanding sentences requiring aspectual coercion and complement coercion, Wernicke's patients performed at normal-like levels only for sentences that did not require these operations.

The Critical Role of Group Studies in Neuropsychology: Comprehension Regularities in Broca's Aphasia

It is shown that the group's performance is stable, and well-delineated, despite intersubject variation whose source is now identified, and promotes studies of groups of brain-damaged patients as a central tool for the investigation of brain/behavior relations.

A blueprint for a brain map of syntax1

It is shown that syntactic movement is consistently related to Broca’s region, albeit in intriguingly varied ways, and the emerging map is used to explore the possibility that this neurological distribution of syntactic operations is not accidental, and that the brain map for syntax is both neurologically and linguistically meaningful.
