Prestimulus beta rhythm influence reaction time during real-time brain-dependent stimuli presentation
P. 6–9.
Aksiotis V., Alexei Ossadtchi
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 participants who was instructed to response immediately after change of stimuli color. As a result of the method application, a longer reaction time in the case of highly synchronized beta oscillations compared to desynchronization was achieved in the simple reaction time task. It indicates, firstly, a crucial role of baseline, prestimulus beta in motor action initiation and, secondly, the possibility to change reaction using adaptive processing and timing of presentation in real-time.

We present a multimodal dataset containing electroencephalography (EEG), electrocardiography (ECG), and video recordings from 49 participants. Each participant completed a single session lasting approximately 45 minutes. During each session they performed five tasks: resting state, inward concentration (focusing on the center of the forehead), outward concentration (visual search), and mind-wandering. EEG data were recorded from ...

Introduction. Video games constitute a special form of digital media characterized by dynamic environments that respond to players’ actions and integrated algorithms. Within psychological research, video games offer better validity compared to traditional automated assessment systems, enabling a naturalistic investigation of various phenomena. Furthermore, video games shape mental processes. These features are widely exploited in international psychological research and are critical ...

Growing evidence suggests the specific systems for emotional information maintenance and processing in working memory, highlighting the role of cognitive domains in emotional awareness. The question of neural basis of social-emotional processing in working memory remains open. We hypothesized that the neural systems supporting working memory for emotional processing may rely on shared ‘core’ networks ...

Motor imagery training under the control of a brain-computer interface (BCI) facilitates motor recovery after stroke. The efficacy of BCI based on electroencephalography (EEG-BCI) has been confirmed by several meta-analyses, but a more convenient and noise-resistant method of near-infrared spectroscopy in the BCI circuit (NIRS-BCI) has been practically unexamined; comparisons of the two types of ...

The work investigates spatial and temporal EEG patterns during real and imagined execution of hand reaching. Six independent sources of electrical activity were identified in the EEG recordings. The sources corresponded to the premotor areas, supplementary motor area, primary motor areas, and posterior parietal cortex. Their activation patterns in the alpha and beta range were ...

Neurorehabilitation of motor functions using a neurointerface (BCI) with feedback is a modern promising area of research. However, there is very little data on muscle activity during the motor imagery of lower limb – an important aspect of rehabilitation. The EMG activity of the lower limb muscles was studied in 42 healthy participants which control ...

Studying mu-rhythm in developmental disorders is crucial for identifying the origin of motor and social malfunctioning. However, the commonly used mu-rhythm experimental protocol, that requires following instructions, is challenging for children with motor and cognitive deficits. Here we present an inclusive experimental procedure that contains passive hand movement, closed and open eyes and hand movement ...

There is a need for empirical indicators that can monitor subtle changes in wakefulness levels with high temporal resolution. We aimed to assess the applicability in this regard of several indices based on the average spectral power of EEG rhythms, as well as the BIS index used in anesthesiology. 26 volunteers participated in an experiment involving forced awakenings ...

Magnetoencephalography (MEG) and electroencephalography (EEG) provide complementary insights into brain activity, yet their distinct biophysical principles influence how normal neurophysiological patterns and artifacts are represented. This study presents a comprehensive qualitative and quantitative analysis of common physiological variants and artifacts in simultaneously recorded MEG and EEG data. We systematically examined patterns such as alpha spindles, ...

In this article, the process of internal pronunciation (covert speech) is associated with the internal speech through an intellectual process such as silent reading. The objective of the research is to compare the EP of visual and auditory perception and internal pronunciation of phonemes and syllables; to classify phonemes, words and syllables from covert speech, ...
