Talk 2022#Day1-1 – Klaus LINKENKAER-HANSEN – Excitation/Inhibition Balance as a Multi-Scale Mechanism Regulating Brain Function
By Klaus Linkenkaer-Hansen (Amsterdam, The Netherlands) et al. The opposing forces of excitation (E) and inhibition (I) fundamentally shape activity at many levels of neuronal organization. Heuristic arguments have favored a certain “E/I balance” to be important for normal brain function, while “E/I imbalance” is considered a pathophysiological mechanism in several neurological and psychiatric disorders. … Continue reading Talk 2022#Day1-1 – Klaus LINKENKAER-HANSEN – Excitation/Inhibition Balance as a Multi-Scale Mechanism Regulating Brain Function
ByEnzo Tagliazucchi (Buenos Aires, Argentina). In the last decades, machine learning (in particular, deep learning) has consolidated as a data-driven way to identify meaningful patterns in large volumes of data. In this talk I will explore the application of deep learning to the problem of identifying signatures of criticality and non-equilibrium dynamics in recordings of … Continue reading Talk 2022#Day1-2 – Enzo TAGLIAZUCCHI – Machine Learning Critical Brain Dynamics
By Moritz Helias (Jülich, Germany). Criticality is deeply related to optimal computational capacity. The lack of a renormalized theory of critical brain dynamics, however, so far limits insights into this form of biological information processing to mean- field results. These methods neglect a key feature of critical systems: the interaction between degrees of freedom across … Continue reading Talk 2022#Day1-4 – Moritz HELIAS – Gell-Mann–Low Criticality in Neural Networks
By Karin Dahmen (Urbana-Champaign, IL). The tasks of neural computation are remarkably diverse. To function optimally, neuronal networks have been hypothesized to operate near a nonequilibrium critical point. We use the framework of nonequilibrium phase transitions to describe the statistics and the dynamics of neuron avalanches in the brain. Measured scaling exponents, exponent relations, and … Continue reading Talk 2022#Day1-5 – Karin DAHMEN – Dynamics of Neuronal Avalanches
Talk 2022#Day1-6 – Miguel MUÑOZ – Quasi-Universal Scaling in Mouse-Brain Neuronal Activity Stems from Edge-Of-Instability Critical Dynamics
By Miguel Muñoz (Granada, Spain). Advancing our knowledge of how the brain processes information remains a key challenge in neuroscience. Importantly, the brain, even at rest, is in an energetically costly state of ongoing activity, whose origin and meaning still need to be fully elucidated. An inspiring hypothesis suggests that such activity is generated by … Continue reading Talk 2022#Day1-6 – Miguel MUÑOZ – Quasi-Universal Scaling in Mouse-Brain Neuronal Activity Stems from Edge-Of-Instability Critical Dynamics
By Dante Chialvo (Buenos Aires, Argentina). It is well known that the behaviour of the correlation functions changes dramatically near criticality. Less clear is how such hallmark properties can be empirically estimated from neural recordings. In this talk I will review old and recent attempts to study this issue.
Spotlight 2022#1 – Hilgo BRUINING – Criticality at the core of precision medicine for neurodevelopmental disorders
By Hilgo Bruining (University Medical Center, Amsterdam, the Netherlands). November 7th, 2022. New treatment developments for neurodevelopmental such as autism have failed to reach clinical implementation due to inter- and intraindividual variability across biological and clinical dimensions. To resolve this situation, we propose to use the framework of excitation/inhibition imbalances in resting-state EEG measurements to … Continue reading Spotlight 2022#1 – Hilgo BRUINING – Criticality at the core of precision medicine for neurodevelopmental disorders
Spotlight 2022#2 – Matthieu AGUILERA – Assessing functional system’s dynamics through longitudinal EEG recordings in a new mouse model of early Alzheimer’s disease
By Matthieu Aguilera (University of Strasbourg, France). November 7th, 2022. Alzheimer’s disease (AD) is a neurodegenerative pathology characterized by a progressive and irreversible deterioration of cognitive functions, especially memory. A challenge in current research on AD is to find a reliable and early marker of the disease. Recently, our team showed that the new humanized … Continue reading Spotlight 2022#2 – Matthieu AGUILERA – Assessing functional system’s dynamics through longitudinal EEG recordings in a new mouse model of early Alzheimer’s disease
By John Beggs (Indiana University, Bloomington, IN). November 7th, 2022. Much evidence seems to suggest the cortex operates near a critical point, yet a single set of exponents defining its universality class has not been found. In fact, when critical exponents are estimated from data, they widely differ across species, individuals of the same species, … Continue reading Spotlight 2022#3 – John BEGGS – Quasicritical Brain Dynamics
