Brain–computer interfaces (BCIs) development is closely related to physics. In this paper, we
review the physical principles of BCIs, and underlying novel approaches for registration …

Epilepsy is one of the brightest manifestations of extreme behavior in living systems.
Extreme epileptic events are seizures, that arise suddenly and unpredictably. Usually …

Self-organized bistability (SOB) stands as a critical behavior for the systems delicately
adjusting themselves to the brink of bistability, characterized by a first-order transition. Its …

We propose a theoretical approach associated with an experimental technique to
quantitatively characterize cognitive brain activity in the perception of ambiguous images …

Neuronal synchronization is important for communication between brain regions and plays a
key role in learning. However, changes in connectivity can lead to hyper-synchronized …

Extreme events are observed on electroencephalographic (EEG) recordings of rodents with
induced ischemic stroke. These events represent themselves as post-stroke epileptic …

The full range of biopsychosocial complexity is mind-boggling, spanning a vast range of
spatiotemporal scales with complicated vertical, horizontal, and diagonal feedback …

We applied methods for determining the recurrence based phase synchronization index and
the coupling directionality based on conditional probabilities of recurrence to analyze the …

This paper presents the results of a study of the characteristics of phase synchronization
between electrocardiography (ECG) and electroencephalography (EEG) signals during …

Electroencephalography is a widespread method to record brain signals with the use of
electrodes located on the surface of the head. This method of recording the brain activity has …
