We characterize the chaotic dynamics of semiconductor lasers subject to either optical or
electrooptical feedback modeled by Lang-Kobayashi and Ikeda equations, respectively. This …

Evolution of cooperation and competition can appear when multiple adaptive agents share
a biological, social, or technological niche. In the present work we study how cooperation …

Understanding causal relationships, or effective connectivity, between parts of the brain is of
utmost importance because a large part of the brain’s activity is thought to be internally …

Highlights • Fundamental caveats and confounds in the methodology of assessing CFC are
discussed. • Significant CFC can be observed without any underlying physiological coupling. …

We show that isochronous synchronization between two delay-coupled oscillators can be
achieved by relaying the dynamics via a third mediating element, which surprisingly lags …

Multielectrode recordings have revealed zero time lag synchronization among remote cerebral
cortical areas. However, the axonal conduction delays among such distant regions can …

In complex networks such as gene networks, traffic systems or brain circuits it is important to
understand how long it takes for the different parts of the network to effectively influence one …

Background Transfer entropy (TE) is a measure for the detection of directed interactions.
Transfer entropy is an information theoretic implementation of Wiener's principle of …

In scientific discourse and the media it is commonplace to state that brains exist to ‘process
information’. Curiously enough, however, we only have a certain understanding of what is …

The analysis of cortical and subcortical networks requires the identification of their nodes, and
of the topology and dynamics of their interactions. Exploratory tools for the identification of …
