Journal ArticleDOI
Transfer entropy--a model-free measure of effective connectivity for the neurosciences
TL;DR: Transfer entropy (TE) improved the detectability of effective connectivity for non-linear interactions, and for sensor level MEG signals where linear methods are hampered by signal-cross-talk due to volume conduction.
Journal ArticleDOI
Multiagent cooperation and competition with deep reinforcement learning
Ardi Tampuu,Tambet Matiisen,Dorian Kodelja,Ilya Kuzovkin,Kristjan Korjus,Juhan Aru,Jaan Aru,Raul Vicente +7 more
TL;DR: The present work shows that Deep Q-Networks can become a useful tool for studying decentralized learning of multiagent systems coping with high-dimensional environments and describes the progression from competitive to collaborative behavior when the incentive to cooperate is increased.
Journal ArticleDOI
Untangling cross-frequency coupling in neuroscience
Juhan Aru,Jaan Aru,Viola Priesemann,Michael Wibral,Luiz Lana,Gordon Pipa,Wolf Singer,Raul Vicente +7 more
TL;DR: This work organizes the available and potential novel statistical/modeling approaches according to their biophysical interpretability of cross-frequency coupling to provide a road map towards an improved mechanistic understanding of CFC.
Journal ArticleDOI
Dynamical relaying can yield zero time lag neuronal synchrony despite long conduction delays.
Raul Vicente,Leonardo L. Gollo,Claudio R. Mirasso,Ingo Fischer,Gordon Pipa,Gordon Pipa,Gordon Pipa +6 more
TL;DR: This work investigates the synchronization properties of a simple network motif and found that, even in the presence of large axonal conduction delays, distant neuronal populations self-organize into lag-free oscillations.
Journal ArticleDOI
Zero-lag long-range synchronization via dynamical relaying.
Ingo Fischer,Raul Vicente,Javier M. Buldú,Michael Peil,Claudio R. Mirasso,M. C. Torrent,Jordi Garcia-Ojalvo +6 more
TL;DR: The results show that zero-lag synchronized chaotic dynamical states can occur over long distances through relaying, without restriction by the amount of delay.
