Опыт работы
- · Yury Shtyrov (Professor, Head of MEG/EEG at the Center of Functionally Integrative Neuroscience, Aarhus University; Visiting Professor/PI at the HSE CDM Centre) has many years of international experience in studying human neurocognitive functions, in particular neurobiological foundations of the human speech and language function. His particular contribution to the science of language has been in uncovering early and automatic stages of language processing and in detailing the time course of spoken language comprehension in the brain. This work has to a large extent contributed to a dramatic change in our understanding of how the brain analyses speech, which has occurred in recent years. It shows how memory traces for linguistic elements in the brain can be probed using objective imaging tools, how they develop with learning, interact on different levels, as well as the interaction between the cognitive systems of language and attention. Most importantly, this work shows that these different processes occur rapidly and in parallel, something that was first met with disbelief but is now becoming generally accepted thanks to this and similar work. We are very pleased to have Prof. Shtyrov as our close collaborator in a range of projects focussed on human mechanisms of comminication, perception and cognitive control using MEG, EEG, TMS, behavioural and other methodologies.

Automatic Lexical Access in Visual Modality: Eye-Tracking Evidence
2018 · ARTICLE · en
Language processing has been suggested to be partially automatic, with some studies suggesting full automaticity and attention independence of at least early neural stages of language comprehension, in particular, lexical access. Existing neurophysiological evidence has demonstrated early lexically specific brain responses (enhanced activation for real words) to orthographic stimuli presented parafoveally even under the condition of withdrawn attention. These studies, however, did not control participants’ eye movements leaving a possibility that they may have foveated the stimuli, leading to overt processing. To address this caveat, we recorded eye movements to words, pseudowords, and non-words presented parafoveally for a short duration while participants performed a dual non-linguistic feature detection task (color combination) foveally, in the focus of their visual attention. Our results revealed very few saccades to the orthographic stimuli or even to their previous locations. However, analysis of post-experimental recall and recognition performance showed above-chance memory performance for the linguistic stimuli. These results suggest that partial lexical access may indeed take place in the presence of an unrelated demanding task and in the absence of overt attention to the linguistic stimuli. As such, our data further inform automatic and largely attention-independent theories of lexical access.
LANGUAGE REHABILITATION IN CHRONIC POST-STROKE APHASIA: A NEUROSCIENTIFIC PERSPECTIVE
2018 · ARTICLE · en
This review focuses on language deficits in post-stroke aphasia, their rehabilitation and potential new developments based on current knowledge of human brain function. Language impairments in post-stroke aphasia often become chronic and cause significant communicative difficulties for patients. Though standard rehabilitation methods provide some language improvements, they are usually moderate and often decay over a period of time. These traditional rehabilitation approaches are usually based on existing conventions formed through decades of clinical practice; whilst valuable, they are not often rooted in up-to-date neuroscientific knowledge. In recent decades, human neuroscience has developed at a very high speed, not least due to the advent of non-invasive brain imaging techniques. Currently, it has reached the stage where neuroscientific knowledge can inform clinical practice, and help upgrade the traditional approaches using modern neuroscience tools. Furthermore, traditional practices typically apply the same routines to different patients, even though the nature of the individual deficit — and hence the care needed — are never the same. For instance, aphasic patients demonstrate a massive variety of improvement patterns during natural language recovery. This might be caused by individual differences in the functioning of language neural networks and their dynamics after stroke. Although the problem of individual variability in aphasia is well-known, there is still no comprehensive understanding of all factors that impact this variability. As we highlight in this review, the issue is of high importance for planning language therapy on individual basis. We also analyze neuroscientific underpinnings and clinical efficiency of a language therapy, which is widely used for chronic aphasia rehabilitation — constraint-induced aphasia therapy.
TRANSCRANIAL DIRECT CURRENT STIMULATION AS A TOOL TO INDUCE LANGUAGE RECOVERY IN PATIENTS WITH POST-STROKE APHASIA
2018 · ARTICLE · ru
In recent years, possible therapeutic effects of transcranial direct current stimulation (tDCS) have been widely investigated in studies dealing with different types of neural pathologies. Initially, tDCS was applied for treatment of patients with motor stroke; later on, it was introduced into studies of patients with Alzheimer’s disease, multiple sclerosis, Parkinson’s disease, schizophrenia and post- stroke aphasia. Recent reviews of tDCS application in patients with post-stroke aphasia did not pro- vide coherent evidence on the tDCS efficiency. There were no uniform protocols of stimulation used, patients’ selection criteria were highly divergent, and the reports of treatment outcomes varied dramatically. In this review, we will focus on the reported heterogeneity of tDCS effects trying to disentangle its putative underpinnings rooted in the diversity of lesion types, aphasia severity and recovery stages. Given the current theoretical models suggesting the qualitatively different patterns of brain activity to accompany post-stroke aphasia recovery, a number of physiological factors should be taken into account to choose optimal tDCS parameters. With this in mind, we assess re- sults of ten studies applying tDCS in post-stroke aphasia treatment, and, based on this analysis, suggest directions for further research in this rapidly developing field.
Testing the Efforts Model of Simultaneous Interpreting: An ERP Study
2018 · ARTICLE · en
We utilized the event-related potential (ERP) technique to study neural activity associated with different levels of working memory (WM) load during simultaneous interpretation (SI) of continuous prose. The amplitude of N1 and P1 components elicited by task-irrelevant tone probes was significantly modulated as a function of WM load but not the direction of interpretation. Furthermore, the latency of the P1 increased significantly with WM load. The WM load effect on N1 latency, however, did not reach significance. Larger negativity under lower WM loads suggests that more attention is available to process the source message, providing the first electrophysiological evidence in support of the Efforts Model of SI. Relationships between the direction of interpretation and median WM load are also discussed.

Task-free auditory EEG paradigm for probing multiple levels of speech processing in the brain
2018 · ARTICLE · en
While previous studies on language processing highlighted several ERP components in relation to specific stages of sound and speech processing, no study has yet combined them to obtain a comprehensive picture of language abilities in a single session. Here, we propose a novel task-free paradigm aimed at assessing multiple levels of speech processing by combining various speech and nonspeech sounds in an adaptation of a multifeature passive oddball design. We recorded EEG in healthy adult participants, who were presented with these sounds in the absence of sound-directed attention while being engaged in a primary visual task. This produced a range of responses indexing various levels of sound processing and language comprehension: (a) P1-N1 complex, indexing obligatory auditory processing; (b) P3-like dynamics associated with involuntary attention allocation for unusual sounds; (c) enhanced responses for native speech (as opposed to nonnative phonemes) from ∼50 ms from phoneme onset, indicating phonological processing; (d) amplitude advantage for familiar real words as opposed to meaningless pseudowords, indexing automatic lexical access; (e) topographic distribution differences in the cortical activation of action verbs versus concrete nouns, likely linked with the processing of lexical semantics. These multiple indices of speech-sound processing were acquired in a single attention-free setup that does not require any task or subject cooperation; subject to future research, the present protocol may potentially be developed into a useful tool for assessing the status of auditory and linguistic functions in uncooperative or unresponsive participants, including a range of clinical or developmental populations.
Selective Social Context-Dependent Role of the Left Medial Prefrontal Cortex in Communication Exchanges
2018 · CHAPTER · en
Previous research showed that under uncertainty (when we are not sure about what the correct answer is) in informal contexts such as chatting with friends, we tend to provide any retrieved information indiscriminately. However, in more formal contexts, like a job interview, we apply a more conservative threshold and balance reporting some information while withholding other answers as a way to provide some information while keeping the accuracy high, if possible. The left medial prefrontal cortex (lmPFC) was suggested as one of the areas linked with self-referential processing in metacognitive decisions. In the present research, we used repetitive transcranial magnetic stimulation (rTMS) to assess the involvement of the lmPFC in two different types of social contexts: formal and informal. Three groups of participants were exposed for 15 minutes to an offline 1-Hz rTMS stimulation of either: (1) lmPFC, (2) control site (rmPFC) or (3) sham (placebo stimulation). Afterwards, participants answered difficult general knowledge questions and rated their confidence in the correctness of their answers. Finally, they decided if they would report or withhold those answers in a formal (job interview) and in informal (chatting with friends) contexts. There were significantly more reported than withheld answers in the informal context for all three groups. However, in the formal context, there were more withheld than reported answers in the lmPFC group, with no differences in the other two groups. No differences in confidence ratings between groups were found. These results suggest a selective involvement of the lmPFC in self-monitoring in formal contexts; its inhibition seems to highlight the need of accuracy in our answers in a job interview over the socially more acceptable behaviour of always providing an answer when asked.
Combined CIAT-tDCS Therapy in Chronic Post-Stroke Aphasia Improves Neural Speech Processing: Neurophysiological and Behavioral Outcomes
2018 · CHAPTER · en
Intensive speech therapy was shown to lead to plastic changes reflected by lexical mismatch negativity (MMN) responses in aphasic patients (Mohr et al., 2016). Since many studies point to the role of the right hemisphere (RH) in aphasia recovery, noninvasive brain stimulation techniques (TMS, tDCS; Shah et al. 2013) usually target RH to facilitate this process. However, individual variance in stimulation-induced neural changes and resulting therapy outcomes are not understood. Here, 14 patients with chronic non-fluent mild-to-moderate aphasia caused by a left middle-cerebral artery stroke underwent Intensive Language-Action Therapy (ILAT, Pulvermüller, 2008) combined with anodal tDCS over the left IFG. To assess speech comprehension mechanisms, lexical MMN paradigm (120 deviant words vs. 487 standard pseudowords) was applied in MEG, before and after therapy for patients and once for a group of 10 controls. To improve the SNR of the responses, we applied a noise bootstrapping procedure with individual noise level computation. We found that the average power of the MMN response in the LH was significantly higher in the patients comparing to the healthy controls (p=0.01). Moreover, the variance of the MMN power increased significantly in the patient group after the treatment. This increase correlated with the behavioural improvements measured as a change of accuracy in a verb generation task (p=0.002). These changes were also associated with clinical improvements in speech comprehension measured by Russian Aphasia Test: scores in a sentence repetition subtest significantly increased after therapy (p = 0.035). No effects were found for the RH. Our results point to the compensatory role of the left hemisphere in the chronic stage of aphasia. They also highlight the role of individual variability in recovery of the language function, suggesting considerable individual differences in the recovery potential. The study continues to investigate these effects in larger samples.
The role of executive control in the activation of manual affordances
2017 · ARTICLE · en
We investigated the role of executive control processes in the activation of manual affordances in two experiments combining stimulus–response compatibility (SRC) and dual-task paradigms. We registered an inverse SRC effect in the presence of a parallel backward-counting task in Experiment 1, and a cancellation of the SRC effect in Experiment 2 when a parallel Stroop-like task was used. We interpret our data as supporting a self-inhibition account of the affordance activation control. Accordingly, the role of executive processes is to prevent self-inhibition in supraliminal conditions: when cognitive resources are depleted by a parallel task, the self-inhibition mechanism becomes active and irrelevantly potentiated affordances are inhibited, leading to the emergence of an inverse SRC effect. In addition, the difference between data patterns observed in the two experiments suggests that the exact roles of the executive processes involved during the activation of affordances may differ. The results suggest a mechanism for action-related activation monitoring based on a flexible control over automatically potentiated actions. The paper discusses the proposed mechanism in detail and outlines further research directions.
Primary motor cortex functionally contributes to language comprehension: An online rTMS study.
2017 · ARTICLE · en
Among various questions pertinent to grounding human cognitive functions in a neurobiological substrate, the association between language and motor brain structures is a particularly debated one in neuroscience and psychology. While many studies support a broadly distributed model of language and semantics grounded, among other things, in the general modality-specific systems, theories disagree as to whether motor and sensory cortex activity observed during language processing is functional or epiphenomenal. Here, we assessed the role of motor areas in linguistic processing by investigating the responses of 28 healthy volunteers to different word types in semantic and lexical decision tasks, following repetitive transcranial magnetic stimulation (rTMS) of primary motor cortex. We found that early rTMS (delivered within 200ms of word onset) produces a left-lateralised and meaning-specific change in reaction speed, slowing down behavioural responses to action-related words, and facilitating abstract words - an effect present only during semantic, but not lexical, decision. We interpret these data in light of action-perception theory of language, bolstering the claim that motor cortical areas play a functional role in language comprehension.
