Disentangling causal webs in the brain using functional Magnetic Resonance Imaging: A review of current approaches
Natalia Z. Bielczyk, Sebo Uithol, Tim van Mourik +3
In the past two decades, functional Magnetic Resonance Imaging has been used to relate neuronal network activity to cognitive processing and behaviour. Recently this approach has b…
Multi-clustered chimeras in large semiconductor laser arrays with nonlocal interactions
J. Shena, J. Hizanidis, P. Hövel +1
The dynamics of a large array of coupled semiconductor lasers is studied for a nonlocal coupling scheme. Our focus is on chimera states, a self-organized spatio-temporal pattern of…
Chimera states in multi-strain epidemic models with temporary immunity
Larissa Bauer, Jason Bassett, Philipp Hövel +2
We investigate a time-delayed epidemic model for multi-strain diseases with temporary immunity. In the absence of cross-immunity between strains, dynamics of each individual strain…
The Same Analysis Approach: Practical protection against the pitfalls of novel neuroimaging analysis methods
Kai Görgen, Martin N. Hebart, Carsten Allefeld +1
Standard neuroimaging data analysis based on traditional principles of experimental design, modelling, and statistical inference is increasingly complemented by novel analysis meth…
Emergent stochastic oscillations and signal detection in tree networks of excitable elements
Justus Kromer, Ali Khaledi-Nasab, Lutz Schimansky-Geier +1
We study the stochastic dynamics of strongly-coupled excitable elements on a tree network. The peripheral nodes receive independent random inputs which may induce large spiking eve…
A Multiscale-Analysis of Stochastic Bistable Reaction-Diffusion Equations
Jennifer Krüger, Wilhelm Stannat
A multiscale analysis of 1D stochastic bistable reaction-diffusion equations with additive noise is carried out w.r.t. travelling waves within the variational approach to stochasti…
