From Chaos to Synchrony in Recurrent Excitatory-Inhibitory Networks with Target-Specific Inhibition
Carles Martorell, Rubén Calvo, Alessia Annibale +1
Biological neural networks can operate in qualitatively distinct dynamical regimes, and transitions between these regimes are thought to underlie changes in computation and behavio…
Microbiome association diversity reflects proximity to the edge of instability
Rubén Calvo, Adrián Roig, Roberto Corral López +3
Recent advances in metagenomics have revealed macroecological patterns or "laws" describing robust statistical regularities across microbial communities. Stochastic logistic models…
Ergodicity Breaking and High-Dimensional Chaos in Random Recurrent Networks
Carles Martorell, Rubén Calvo, Adrián Roig +2
The neural model introduced by Sompolinsky, Crisanti, and Sommers (SCS) nearly four decades ago has become a paradigmatic framework for studying complex dynamics in random recurren…
Robust Scaling in Human Brain Dynamics Despite Latent Variables and Limited Sampling Distortions
Rubén Calvo, Carles Martorell, Adrián Roig +1
The idea that information-processing systems operate near criticality to enhance computational performance is supported by scaling signatures in brain activity. However, external s…
