Synergy mediates Long-Range Correlations in the Visual Cortex Near Criticality Open
Long-range correlations are a key signature of systems operating near criticality, indicating spatially-extended interactions across large distances. These extended dependencies underlie other emergent properties of critical dynamics, such…

Information dynamics and the emergence of high-order individuality in ecosystems Open
At what level does natural selection occur? When considering the reproductive dynamics of interacting and mutating agents, it has long been debated whether selection is better understood by focusing on the individual or if hierarchical sel…

Synergistic small worlds that drive technological sophistication Open
It is a well-known fact that economic growth goes hand in hand with improvements in technological sophistication. While critical to such sophistication, the nature and underlying structure of the input interactions taking place inside prod…

Quantifying Hierarchical Selection Open
At what level does selective pressure effectively act? When considering the reproductive dynamics of interacting and mutating agents, it has long been debated whether selection is better understood by focusing on the individual or if hiera…

Swinging, Fast and Slow: Multiscale Synchronisation Dynamics Reveals the Impact of an Improvisatory Approach to Performance on Music Experience Open
Experiences of collective creative activities play an essential role in human societies, yet these experiences are particularly hard to capture, making their scientific scrutiny extremely challenging. Here we investigate the experience of …

Synergistic Small Worlds that Drive Technological Sophistication Open
Advanced economies exhibit a high degree of sophistication in the creation of various products. While critical to such sophistication, the nature and underlying structure of the interactions taking place inside production processes remain …

Psychedelics and schizophrenia: Distinct alterations to Bayesian inference Open
Schizophrenia and states induced by certain psychotomimetic drugs may share some physiological and phenomenological properties, but they differ in fundamental ways: one is a crippling chronic mental disease, while the others are temporary,…

Interpretable XGBoost Based Classification of 12-lead ECGs Applying Information Theory Measures From Neuroscience Open
Automated ECG classification is a standard feature in many commercial 12-Lead ECG machines. As part of the Physionet/CinC Challenge 2020, our team, "Mad-hardmax", developed an XGBoost based classification method for the analysis of 12-Lead…

Tangled Worldview Model of Opinion Dynamics Open
We study the joint evolution of worldviews by proposing a model of opinion dynamics, which is inspired in notions from evolutionary ecology. Agents update their opinion on a specific issue based on their propensity to change – asserted by …

The Improvisational State of Mind: A Multidisciplinary Study of an Improvisatory Approach to Classical Music Repertoire Performance Open
The recent re-introduction of improvisation as a professional practice within classical music, however cautious and still rare, allows direct and detailed contemporary comparison between improvised and "standard" approaches to performances…

Achieving perfect coordination amongst agents in the co-action minority game Open
We discuss the strategy that rational agents can use to maximize their expected long-term payoff in the co-action minority game. We argue that the agents will try to get into a cyclic state, where each of the $(2N +1)$ agent wins exactly $…
