Brain-computer interfaces find application in a number of different areas and have the potential to be used for research as well as for practical purposes. The clinical use of BCI includes current studies on neurorehabilitation ([Frolov et al., 2013; Ang et al., 2010]), and there is the prospect of using BCI to restore movement and ...

Objective. Speech decoding, one of the most intriguing brain-computer interface applications, opens up plentiful opportunities from rehabilitation of patients to direct and seamless communication between human species. Typical solutions rely on invasive recordings with a large number of distributed electrodes implanted through craniotomy. Here we explored the possibility of creating speech prosthesis in a minimally ...

Условно-патологический альфа-паттерн как вариант ЭЭГ бодрствования при фармакорезистентной эпилепсии
Arkhipova N., Чухловин А. А., Aleksandrov M. et al., Педиатр 2017 Т. 8 № 4 С. 48-56
В результате патоморфоза механизмов генерации биоэлектрической активности при развернутой клинической картине эпилепсии на интериктальной ЭЭГ возможна редукция эпилептиформных изменений. В таких случаях может регистрироваться паттерн с доминирующей альфа-активностью. Целью исследования являлась систематизация вариантов альфа-активности у пациентов с фармакорезистентной эпилепсией. Обследована группа из 50 пациентов с фармакорезистентной эпилепсией в возрасте от 20 до 55 лет, находившихся на лечении в клинике Российского ...

The goal of the present study was to investigate the interaction between different senses of polysemous nouns (metonymies and metaphors) and different meanings of homonyms using the method of event-related potentials (ERPs) and a priming paradigm. Participants read two-word phrases containing ambiguous words and made a sensicality judgment. Phrases with polysemes highlighted their literal sense ...

Event-related potentials during facial emotion recognition have been studied for more than twenty years. Nowadays, there has been a growing interest in the use of naturalistic stimuli. This research was aimed, therefore, at studying event-related potentials (ERP) during recognition of dynamic facial neutral-to-emotional expressions, more ecologically valid than static faces. We recorded the ERP of ...

Cognitive reappraisal and expressive suppression are well-studied strategies of emotion regulation (ER). However, the results on their physiological basis are controversial. While in some studies, ER was accompanied by the inhibition of nervous system, others suggested that ER even might increase arousal and engagement. We calculated the inter-subject correlation (ISC) and indices of engagement, valence ...

In this research we compare the performance of different data mining techniques in the analysis of electroencephalogram (EEG) data. We study the question od predicting post-comatose neuro-developmental scores based mainly on statistical features of the EEG recordings. We compare results from applying different data mining techniques, such as the Elastic Net, Lasso, Gaussian Support Vector ...

This paper introduces a novel numerical method for the inverse problem of electroencephalography(EEG). We pose the inverse EEG problem as an optimal control (OC) problem for Poisson’s equation. The optimality conditions lead to a variational system of differential equations. It is discretized directly in finite-element spaces leading to a system of linear equations with a ...

Cortical and autonomic responses during staged Taoist meditation: two distinct meditation strategies
Volodina M., Smetanin N., Lebedev M. et al., Plos One 2021 Vol. 16 No. 12 Article e0260626
Meditation is a consciousness state associated with specific physiological and neural correlates. Numerous investigations of these correlates reported controversial results which prevented a consistent depiction of the underlying neurophysiological processes. Here we investigated the dynamics of multiple neurophysiological indicators during a staged meditation session. We measured the physiological changes at rest and during the guided ...

This research was focused on postdictive properties of apparent motion — an illusion of movement resulting from successive presentation of two dots. Obviously, the mechanisms of integration of two dots’ representations can take place only after the second dot is presented. There are two alternatives of what exactly happens. Firstly, a person becomes aware of ...

In the present study, a fast and adaptive technique for the presentation of stimuli based on ongoing brain rhythm is described. Sensorimotor cortical mu rhythm (divided by two components: alpha (mu) and beta) was used as target for assessment of prestimulus rhythm’s power influence on the consequent reaction time. The final sample consisted of 15 ...

Changes in EEG were investigated in two ground-based hypogravity simulation experiments: 21-d dry immersion (DI) and 21-d bed rest (BR). Ten volunteers participated in DI, and 6 volunteers in BD. EEG was recorded before and on days 5 and 17 of DI and BR. EEG spectral power was analyzed using the fast Fourier transform. EEG ...

Relating behavioral and neuroimaging measures is essential to understanding human brain function. Often, this is achieved by computing a correlation between behavioral measures, e.g., reaction times, and neurophysiological recordings, e.g., prestimulus EEG alpha-power, on a single-trial-basis. This approach treats individual trials as independent measurements and ignores the fact that data are acquired in a temporal order. It has ...

Rapid technological advancements have led to a significant progress in research methods for cognitive sciences. Today scientists can easily use various neurophysiological methods in order to study human behavior and its underlying brain mechanisms and cognitive processes. Among such methods is eye-tracking — a technique allowing recording and analysis of the online oculomotor behavior. Since ...

Human societies benefit from social norms that increase cooperation and support social order. Hence, the understanding of effective mechanisms enforcing norms is crucial. One of such mechanisms is “third-party punishment” (TPP) – a form of social punishment that could be delivered by a third-party, not directly affected by the actions of the norm violator.

Objective. Brain-computer interface (BCI) systems are known to be vulnerable to variabilities in background states of a user. Usually, no detailed information on these states is available even during the training stage. Thus there is a need in a method which is capable of taking background states into account in an unsupervised way. Approach. We ...

The study presents a novel approach designed to detect time-continuous states in time-series data, called the State-Detecting Algorithm (SDA). The SDA operates on unlabeled data and detects optimal change-points between intrinsic functional states in time-series data based on an ensemble of Ward's hierarchical clustering with time-connectivity constraint. The algorithm chooses the best number of states ...

The most common tools to understand perception of food products are hall tests,
surveys and observations. However, these approaches require large samples to get reliable
results and they are rather costly and time-consuming. Furthermore, they are also highly
expert-dependent and rely on the assumption that study participants can express their
preferences consciously and explicitly. In our paper, we suggest ...
