Bistable Firing Pattern in a Neural Network Model

Protachevicz, Paulo; Borges, Fernando S.; Lameu, Ewandson Luiz; Ji, Peng; Iarosz, Kelly; Kihara, Alexandre; Caldas, Ibere; Szezech, Jose Danilo; Baptista, Murilo; Macau, Elbert Einstein Nehrer; Antonopoulos, Chris; Batista, Antonio M.; Kurths, Jürgen

Excessively high, neural synchronization has been associated with epileptic seizures, one of the most common brain diseases worldwide. A better understanding of neural synchronization mechanisms can thus help control or ...

Diminished heart beat non-stationarities in congestive heart failure

Camargo, Sabrina; Riedl, Maik; Anteneodo, Celia; Kurths, Jürgen; Wessel, Niels

Studies on heart rate variability (HRV) have become popular and the possibility of diagnosis based on non-invasive techniques compels us to overcome the difficulties originated on the environmental changes that can affect ...

Exploring Brain Function from Anatomical Connectivity

Zamora López, Gorka; Zhou, Changsong; Kurths, Jürgen

The intrinsic relationship between the architecture of the brain and the range of sensory and behavioral phenomena it produces is a relevant question in neuroscience. Here, we review recent knowledge gained on the architecture ...

Increasing Human Performance by Sharing Cognitive Load Using Brain-to-Brain Interface

Maksimenko, Vladimir A.; Hramov, Alexander E.; Frolov, Nikita; Lüttjohann, Annika; Nedaivozov, Vladimir O.; Grubov, Vadim; Runnova, Anastasia E.; Makarov, Vladimir V.; Kurths, Jürgen; Pisarchik, Alexander

Brain-computer interfaces (BCIs) attract a lot of attention because of their ability to improve the brain's efficiency in performing complex tasks using a computer. Furthermore, BCIs can increase human's performance not ...

Influence of Delayed Conductance on Neuronal Synchronization

Protachevicz, Paulo R.; Borges, Fernando S.; Iarosz, Kelly C.; Baptista, Murilo S.; Lameu, Ewandson L.; Hansen, Matheus; Caldas, Iberê L.; Szezech, José D.; Batista, Antonio M.; Kurths, Jürgen

In the brain, the excitation-inhibition balance prevents abnormal synchronous behavior. However, known synaptic conductance intensity can be insufficient to account for the undesired synchronization. Due to this fact, we ...

Instantaneous Cardiac Baroreflex Sensitivity: xBRS Method Quantifies Heart Rate Blood Pressure Variability Ratio at Rest and During Slow Breathing

Wessel, Niels; Gapelyuk, Andrej; Weiß, Jonas; Schmidt, Martin; Kraemer, Jan F; Berg, Karsten; Malberg, Hagen; Stepan, Holger; Kurths, Jürgen

Spontaneous baroreflex sensitivity (BRS) is a widely used tool for the quantification of the cardiovascular regulation. Numerous groups use the xBRS method, which calculates the cross-correlation between the systolic ...

Reconstructing complex system dynamics from time series: a method comparison

Hassanibesheli, Forough; Boers, Niklas; Kurths, Jürgen

Modeling complex systems with large numbers of degrees of freedom has become a grand challenge over the past decades. In many situations, only a few variables are actually observed in terms of measured time series, while ...

Spontaneous baroreflex sensitivity: sequence method at rest does not quantify causal interactions but rather determines the heart rate to blood pressure variability ratio

Wessel, Niels; Gapelyuk, Andrej; Kraemer, Jan F; Berg, Karsten; Kurths, Jürgen

Objective: In order to quantify spontaneous baroreflex sensitivity (BRS) many groups use the sequence method (SME). In this paper we test the hypothesis that SME is quantifying causal interactions of pontaneous BRS at rest ...

The Stress and Vascular Catastrophes in Newborn Rats: Mechanisms Preceding and Accompanying the Brain Hemorrhages

Glushkovskaya, Oxana; Borisova, Ekaterina; Abakumov, Maxim; Gorin, Dmitry; Avramov, Latchezar; Fedosov, Ivan; Namykin, Anton; Abdurashitov, Arkady; Serov, Alexander; Pavlov, Alexey; Zinchenko, Ekaterina; Lychagov, Vlad; Navolokin, Nikita; Shirokov, Alexander; Maslyakova, Galina; Zhu, Dan; Luo, Qingming; Chekhonin , Vladimir P.; Tuchin, Valery; Kurths, Jürgen

In this study, we analyzed the time-depended scenario of stress response cascade preceding and accompanying brain hemorrhages in newborn rats using an interdisciplinary approach based on: a morphological analysis of brain ...
