INTRODUCTION Neuroimaging and lesion studies indicate a left hemisphere network for verb and verb argument structure processing, involving both frontal and temporoparietal brain regions. Although their verb comprehension is generally unimpaired, it is well known that individuals with agrammatic aphasia often present with verb production deficits, characterized by an argument structure complexit...

Agrammatism is characterized by morphosyntactic deficits in production of sentences. Studies dealing with the treatment of these deficits are scarce and their results controversial. The present study describes the rehabilitation of a case diagnosed as chronic Broca's aphasia, with agrammatism, using a method directed to sentence structural deficits. The method aims to expand the grammatical rep...

Severe hemi-spatial neglect, anosognosia, contralateral hypokinesia, aprosodia, and visual-spatial constructive difficulties--typically seen in right-handers with right hemisphere lesions--were observed in a left-handed patient with an acute left frontal cortical and subcortical infarct. There was no evidence of accompanying aphasia and the neglect syndrome gradually resolved over a 2-week peri...

Functional connectivity among brain regions has been investigated via an analysis of correlations between regional signal fluctuations recorded in magnetic resonance (MR) images obtained in a steady state. In comparison with studies of functional connectivity that utilize task manipulations, the analysis of correlations in steady state data is less susceptible to confounds arising when function...

A debated issue in the relationship between language and thought is how our linguistic abilities are involved in understanding the intentions of others ('mentalizing'). The results of both theoretical and empirical work have been used to argue that linguistic, and more specifically, grammatical, abilities are crucial in representing the mental states of others. Here we contribute to this debate...

Accuracy Group abstract accuracy. Five of the nine comprehension questions in each question set pertained to abstract information not contained in the reading passages. These questions constituted the abstract question set. The abstract question accuracy ranged from 0% to 100% (Median = 54, Mean = 54, SD = 32.73) for the high-context condition, 0% to 100% (Median = 40, Mean = 44, SD = 35.02) fo...

Despite the ubiquity of inner speech in our mental lives, methods for objectively assessing inner speech capacities remain underdeveloped. The most common means of assessing inner speech is to present participants with tasks requiring them to silently judge whether two words rhyme. We developed a version of this task to assess the inner speech of a population of patients with aphasia and corres...

PURPOSE This article addresses complexity in the context of treatment for sentence structural impairments in agrammatic aphasia, with emphasis on noncanonical sentences involving linguistic movement and their related counterparts. Extensions of the complexity effect to recovery of canonical sentences also are discussed, stressing the linguistic properties of verbs as well as grammatical morphol...

The vulnerability of time reference, either marked by means of verbal morphology or by adverbs, has been established in an extensive array of languages in agrammatic aphasia. Recent studies (Bastiaanse, 2008; Lee et al., 2008; Nanousi et al., 2006; Martínez-Ferreiro, 2010; Yarbay Duman and Bastiaanse, 2009; among others) have determined that far from being general, the observed deficit is sensi...

The neural processing loop of language is complex but highly associated with Broca's and Wernicke's areas. The left dominance of these two areas was the earliest observation of brain asymmetry. It was demonstrated that the language network and its functional asymmetry during resting state were reproducible across institutions. However, the temporal reliability of resting-state language network ...
