Diurnal trend in EEG interhemispheric asymmetry in endogenous depressions

open access: yesНеврология, нейропсихиатрия, психосоматика, 2011
A trend in EEG interhemispheric asymmetry was studied in patients with endogenous depressions in morning and evening hours. In the morning, the spectral power of alpha rhythm particularly in the occipital cortical regions, proved to be higher than that ...

Evidence that alpha blocking is due to increases in system-level oscillatory damping not neuronal population desynchronisation

open access: yesNeuroImage, 2020
The attenuation of the alpha rhythm following eyes-opening (alpha blocking) is among the most robust features of the human electroencephalogram with the prevailing view being that it is caused by changes in neuronal population synchrony. To further study

Frequency Characteristics of Rhythm Non-Assimilation in Canine Ventricular Fibrillation

open access: yesОбщая реаниматология, 2010
Ventricular fibrillation is the main cause of sudden cardiac death in many countries, including Russia; therefore to study ventricular fibrillation is an urgent problem.

Attention explores space periodically at the theta frequency [PDF]

open access: yes, 2019
Voluntary attention is at the core of a wide variety of cognitive functions. Attention can be oriented to and sustained at a location or reoriented in space to allow processing at other locations—critical in an ever-changing environment. Numerous studies

The interpretation of mu suppression as an index of mirror neuron activity: past, present and future [PDF]

open access: yesRoyal Society Open Science, 2017
Mu suppression studies have been widely used to infer the activity of the human mirror neuron system (MNS) in a number of processes, ranging from action understanding, language, empathy and the development of autism spectrum disorders (ASDs). Although mu

Electroencephalographic accompaniment of quantitative-qualitative blood pressure clusters in patients of Truskavets’ spa

open access: yesJournal of Education, Health and Sport, 2021
Background. Earlier we studied the autonomic and endocrine accompaniments of quantitative-qualitative blood pressure (BP) clusters of profile patients of Truskavets’ spa.

Infants' mu suppression during the observation of real and mimicked goal-directed actions [PDF]

open access: yes, 2012
Since their discovery in the early 1990s, mirror neurons have been proposed to be related to many social-communicative abilities, such as imitation. However, research into the early manifestations of the putative neural mirroring system and its role in ...

EEG-based cognitive control behaviour assessment: an ecological study with professional air traffic controllers [PDF]

open access: yes, 2017
Several models defining different types of cognitive human behaviour are available. For this work, we have selected the Skill, Rule and Knowledge (SRK) model proposed by Rasmussen in 1983. This model is currently broadly used in safety critical domains,

Sensorimotor and Posterior Brain Activations During the Observation of Illusory Embodied Fake Hand Movement

open access: yesFrontiers in Human Neuroscience, 2019
In the rubber hand illusion (RHI), the subject recognizes a fake hand as his or her own. We recently found that the observation of embodied fake hand movement elicited mu-rhythm (8–13 Hz) desynchronization on electroencephalography (EEG), suggesting ...

Cross-frequency phase-amplitude coupling as a mechanism for temporal orienting of attention in childhood [PDF]

open access: yes, 2018
Temporal orienting of attention operates by biasing the allocation of cognitive and motor resources in specific moments in time, resulting in the improved processing of information from expected compared with unexpected targets.
