OBJECTIVES To review the literature on the specific role of the right cerebral hemisphere during recovery from aphasia in order to address the lack of consensus among authors. To derive a theoretical model reconciling the controversial findings in the literature. METHODS Initial PubMed, MEDLINE (1946 to 5 May 2012) and PsycINFO (1806 to first week June(More)
This study investigated the neural correlates of second-language lexical acquisition in terms of learning phase and word type. Ten French-speaking participants learned 80 Spanish words-40 cognates, 40 non-cognates-by means of a computer program. The learning process included the early learning phase, which comprised 5 days, and the consolidation phase,(More)
Research on the neural substrate of aphasia recovery has consistently increased since the advent of functional neuroimaging. The evidence from therapy-induced aphasia recovery studies shows that better recovery results from the reactivation of left hemisphere function; still, the specific left hemisphere key areas that sign successful outcome with a(More)
Recent advances in the field of communication sciences have led to the description of acquired communication disorders affecting pragmatic skills in patients with brain damage. The present article discusses the impact of such findings on the clinical concept of aphasia. Through reference to a number of articles contained in this Special Issue, it must be(More)
This event-related functional magnetic resonance imaging (fMRI) study reports on the impact of semantic feature analysis (SFA) therapy on the neural substrate sustaining the recovery from severe anomia in two patients: one participant was diagnosed with primary progressive aphasia (PPA) 2 years before this study; the other participant acquired aphasia 8(More)
Bilinguals must focus their attention to control competing languages. In bilingual aphasia, damage to the fronto-subcortical loop may lead to pathological language switching and mixing and the attrition of the more automatic language (usually L1). We present the case of JZ, a bilingual Basque-Spanish 53-year-old man who, after haematoma in the left basal(More)
Previous research on participants with aphasia has mainly been based on standard functional neuroimaging analysis. Recent studies have shown that functional connectivity analysis can detect compensatory activity, not revealed by standard analysis. Little is known, however, about the default-mode network in aphasia. In the current study, we studied changes(More)
The goal of this paper is to discuss experimental design options available for establishing the effects of treatment in studies that aim to examine the neural mechanisms associated with treatment-induced language recovery in aphasia, using functional magnetic resonance imaging (fMRI). We present both group and single-subject experimental or case-series(More)
The study of the neural basis of syntactic processing has greatly benefited from neuroimaging techniques. Research on syntactic processing in bilinguals has used a variety of techniques, including mainly functional magnetic resonance imaging (fMRI) and event-related potentials (ERP). This paper reports on a functional near-infrared spectroscopy (fNIRS)(More)
This paper addresses the interaction between a particular cognitive property inherent to the human brain, i.e., the capacity to learn how to process written information in a manner such that reading words aloud can become a standard aspect of overt behavior, and some of the culture-linked characteristics of the written codes invented by the species. First,(More)
