Using a cross-modal lexical priming technique we provide an on-line examination of the ability of aphasic patients to construct syntactically licensed dependencies in real time. We show a distinct difference between Wernicke's and Broca's aphasic patients with respect to this form of syntactic processing: the Wernicke's patients link the elements of dependency relations in the same manner as do neurologically intact individuals; the Broca's patients show no evidence of such linkage. These… 
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 neurology of syntax: Language use without Broca's area

Five empirical arguments are presented: experiments in sentence comprehension, cross-linguistic considerations, grammaticality and plausibility judgments, real-time processing of complex sentences, and rehabilitation, which indicate that language is a distinct, modularly organized neurological entity.
Revisiting the role of Broca's area in sentence processing: Syntactic integration versus syntactic working memory
Hemodynamic responses elicited while participants processed German indirect wh‐questions strongly suggest that Broca's area plays a critical role in syntactic working memory during online sentence comprehension.
On Processing Lexical Meanings in Aphasia and Alzheimer's Disease: Some (Re)Considerations
The view that "word-level priming" (WLP) is not a sufficient task to tap in the time course of lexical activation during online processing is favored and initial claims regarding automatic or modularized lexical processing are shown to be premature.
Activation of Broca's area by syntactic processing under conditions of concurrent articulation
The results of this experiment provide strong evidence that the increase in blood flow seen in Broca's area in association with processing syntactically complex structures is not due to subvocal rehearsal of those structures, but rather results from processing syntactic forms themselves.
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.
Syntax and the Brain: Disentangling Grammar by Selective Anomalies
Findings provide original in vivo evidence that these brain structures, whose individual contribution has been highlighted by clinical studies, constitute a neural network selectively engaged in morphological and syntactic computation.


Functional localization in the brain with respect to syntactic processing
The data show that Wernicke's patients can link the elements of dependency relations in the same way as neurologically intact subjects, even for sentences that they do not understand, and suggest that comprehension limitations statable in syntactic terms can be traced to changes in cortically localizable processing resources.
Temporal Constraints on Language Processing: Syntactic Priming in Broca's Aphasia
The findings suggest that language processing can break down once activation of different types of linguistic information does not follow the normal time pattern.
The Effects of Focal Brain Damage on Sentence Processing: an examination of the neurological organization of a mental module
It is proposed that in agrammatism, the modularity of word access during sentence comprehension is rendered less efficient but not lost, and a number of broader issues involved in the use of pathological material to infer characteristics of the neurological organization of cognitive architecture are considered.
An On-Line Analysis of Syntactic Processing in Broca′s and Wernicke′s Aphasia
This paper presents data concerning the ability of Broca's and Wernicke's aphasic patients to link moved constituents and empty elements in real time and discusses these data in the context of some current grammar-based theories of comprehension limitations in aphasia.
Verb-Argument Structure Processing in Complex Sentences in Broca′s and Wernicke′s Aphasia
It is found that normal control subjects and Broca's aphasic patients are sensitive to the thematic properties of verbs, regardless of sentence type, and there is a double-dissociation between the operation of accessing a verb's thematic Properties and theoperation of computing the trace-antecedent relation.
Real-time examinations of lexical processing in aphasics
We argue that the lesion localizing value of disruptions to modular information processing systems emerges most clearly from on-line analyses of processing. In this respect we seek to show that left
Theoretical perspectives on language deficits
This critical history of research on acquired language deficits (aphasias) demonstrates the usefulness of linguistic analysis of aphasic syndrome for neuropsychology, linguistics, and psycholinguistics and concludes that the use of grammatical tools for the description of the aphasias is critical.
