Executive functions are an important ability of human brain to program, regulate and control various cogni tive processes; one of these processes is the voluntary task switching. However, the sex differences in this pro cess are poorly studied. In our study, these differences were investigated in 70 healthy subjects (36 men and 34 women) aged 21–48 years by ...

Background: Previous studies have shown that individuals with aphasia have impairments in switching attention compared to healthy controls. However, there is insufficient information about the characteristics of switching attention within one task and whether attention deficits vary depending on aphasia type and lesion location. We aimed to address these knowledge gaps by investigating characteristics of ...

Non-fluency represented in cerebrocerevellar network: an fMRI study of overt action naming in non-fluent aphasia
, , et al., , in : International Symposium on Functional Neuroimaging: Basic Research and Clinical Applications. Abstracts. : MSUPE, 2012. P. 36-38.
Key characteristics of non-fluent (Broca, motor) aphasia are, among others, verb finding difficulties and effortful speech output. These characteristics are related to different levels of speech production (lexical retrieval and motor execution). This study was aimed at identifying normative brain activation related to verb production in healthy individuals, as well as patterns of its reorganization ...

Background: The distribution of pronouns varies cross-linguistically. This distribution has led to conflicting results in studies that investigated pronoun resolution in agrammatic indviduals. In the investigation of pronominal resolution, the linguistic phenomenon of “resumption” is understudied in agrammatism. The construction of pronominal resolution in Akan presents the opportunity to thoroughly examine resumption. Aims: To start, the ...

‘Moderate global aphasia’: A generalized decline of language processing caused by glioma surgery but not stroke
, , et al., Brain and Language 2022 Vol. 224 Article 105057
Unlike stroke, neurosurgical removal of left-hemisphere gliomas acts upon a reorganized language network and involves brain areas rarely damaged by stroke. We addressed whether this causes the profiles of neurosurgeryand stroke-induced language impairments to be distinct. K-means clustering of language assessment data (neurosurgery cohort: N = 88, stroke cohort: N = 95) identified similar profiles ...

Currently there is a need for standardized language assessment test in Russian. Our group has developed Russian Aphasia Test (RAT) based on modern psycholinguistic models and psychometric principles, taking into account existing standardized tests in other languages. RAT allows to separately assess each level of linguistic processing: from phonemic perception to discourse. Here we present ...

What Do Language Disorders Reveal about Brain–Language Relationships? From Classic Models to Network Approaches

Studies of language disorders have shaped our understanding of brain–language relationships over the last two centuries. This article provides a review of this research and how our thinking has changed over the years regarding how the brain processes language. In the 19th century, a series of famous case studies linked distinct speech and language functions ...

The article considers the relationship between the language biography of a patient with aphasia and the process of her speech rehabilitation. The research project focuses on the problem of predicting the structure of mental lexicon in patients with aphasia via modeling it in native speakers from the same socio-professional groups without speech disorders. The process ...

Non-invasive brain stimulation (NIBS) techniques combined with behavioral speech/language therapies have recently been suggested as a promising method for language recovery in people with aphasia (PWA). Repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) are currently the most common types of NIBS for aphasia rehabilitation. In this study, we combined either rTMS ...

Previous clinical research has shown a positive effect of instrumentality on verb retrieval in individuals with aphasia. Performance on instrumental verbs incorporating an obligatory tool into their conceptual representation (e.g., to cut) is more accurate compared to non-instrumental verbs (e.g., to tear), possibly due to more specific conceptual representations of instrumental verbs. Seeking the neural correlates of ...

The aim of this paper is to compare and analyze two approaches to aphasia: the systemic dynamic localization of higher mental functions theory developed by A.R. Luria and neurocognitive dual-route model. To our knowledge, comparative analysis of these two theories was never done before. We found similarities between these two theories, as well as differences ...

The present study aims to contribute to the ongoing discussion about the impact of discourse-linking deficits on the performance of individuals with aphasia by providing new data from a set of rarely investigated constructions: sentences in which a clitic pronoun coexists alongside with the full DP it agrees with. To do so, we use data ...

fMRI language mapping studies report right-hemispheric contribution to language in healthy individuals. However, it remains unclear whether these right-hemispheric patterns of activity are critical for language, which is highly relevant for clinical preoperative language mapping. The available findings are controversial. In this study, we first measured individual patterns of language lateralization with an fMRI language localizer ...

In modern linguistics and psycholinguistics speech disfluencies in real fluent speech are a well-known phenomenon. But it’s not still clear which components of brain systems are involved into its comprehension in a listener’s brain.

Several studies have shown selective deficits in the production and comprehension of verb forms referring to the past. On the basis of this evidence the Past Discourse Linking Hypothesis (Bastiaanse et al., 2011) suggests that individuals with aphasia have difficulties with verb forms referring to the past, in comparison to non-past forms such as the ...

Глаголы физического действия (англ. motor verbs) – это семантический класс глаголов, обозначающих действие, выполняемое какой-либо частью тела (например, рвать, щекотать). Инструментальные глаголы (англ. instrumental verbs) обозначают действие, для выполнения которого необходимо использование инструмента, не являющегося частью тела (например, пилить, вязать); являются подклассом глаголов физического действия. Представляет интерес то, связана ли обработка глаголов этих семантических классов ...
