Spotlight 2024 – Day3 – #4 | – Afshin MONTAKHAB – Criticality and phase transition in a network model of neuronal dynamics with synaptic plasticity
By Afshin Montakhab (California Polytechnic State University, San Luis Obispo, California). November 8th, 2024. In this work, we study a discrete probabilistic neuron-based model on a random network governed by specific dynamic rules to investigate potential phase transitions, including absorbing, synchronization, and chaotic transitions. The primary objective is to determine how these transitions contribute to … Continue reading Spotlight 2024 – Day3 – #4 | – Afshin MONTAKHAB – Criticality and phase transition in a network model of neuronal dynamics with synaptic plasticity
Spotlight 2024 – Day3 – #2 | – Antonio FONTENELE – Neuromodulatory control of critical brain dynamics
By Antonio Fontenele (University of Arkansas, Fayetteville, AR). November 8th, 2024. It has long been suggested that the brain operates near the critical point of a phase transition. However, the mechanisms by which the brain mediates this criticality remain poorly understood. In this study, we propose that the arousal system acts as a key biological … Continue reading Spotlight 2024 – Day3 – #2 | – Antonio FONTENELE – Neuromodulatory control of critical brain dynamics
Spotlight 2024 – Day3 – #1 | – Bryan DANIELS – Neural tuning for perceptual decisions
By Bryan Daniels (Arizona State University, Tempe, AZ). November 8th, 2024. While drift-diffusion models are known to be good at explaining decision dynamics at a coarse scale, there is still no consensus about the detailed neural mechanisms that produce these dynamics. Data from macaque cortical neurons shows that a perceptual decision appears to occur in … Continue reading Spotlight 2024 – Day3 – #1 | – Bryan DANIELS – Neural tuning for perceptual decisions
Spotlight 2024 – Day2 – #4 | – Davide CONTE – Inferring Global Exponents in Subsampled Neural Systems from Power Spectrum and DFA
By Davide Conte (University of Campania “Luigi Vanvitelli”, Caserta, Italy). November 7th, 2024. Understanding criticality in neural networks is essential for deciphering brain function and detecting pathological deviations. However, neural recordings often capture only a small fraction of the system, meaning that the local, subsampled behaviour may not accurately reflect global dynamics. In this study, … Continue reading Spotlight 2024 – Day2 – #4 | – Davide CONTE – Inferring Global Exponents in Subsampled Neural Systems from Power Spectrum and DFA

By Damián Dellavale (Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET), Departamento de Física Médica (DFM), Instituto de Nanociencia y Nanotecnología (INN), Centro Atómico Bariloche (CAB)). November 7th, 2024. Brain oscillations, broadband 1/f activity and neuronal avalanches (NAs) are valuable conceptualizations extensively used to interpret brain data, yet, these perspectives have mainly progressed in parallel … Continue reading Spotlight 2024 – Day2 – #3 | – Damián DELLAVALE – Linking neuronal avalanches with oscillatory and broadband 1/f activities in the resting human brain
Spotlight 2024 – Day2 – #2 | – Sheng WANG – Assessing Seizure Risk in a Low-Dimensional Latent Space Derived from Brain Criticality Biomarkers
By Sheng H. Wang (CEA/NeuroSpin & Inria/MIND, France; University of Helsinki & Aalto University.). November 7th, 2024. Identifying the epileptogenic zone (EZ) for epilepsy surgery is challenging due to the unique complexity of each patient’s pathology. We have shown that individual EZs may encompass synchronized components with high-dimensional (high-D) criticality features. However, high feature dimensionality … Continue reading Spotlight 2024 – Day2 – #2 | – Sheng WANG – Assessing Seizure Risk in a Low-Dimensional Latent Space Derived from Brain Criticality Biomarkers
Spotlight 2024 – Day2 – #1 | – Gregory LEPEU – The critical dynamics of hippocampal seizures
By Grégory LEPEU (Lausanne University Hospital, Switzerland). November 7th, 2024. Epilepsy is defined by the abrupt emergence of harmful seizures, but the nature of these regime shifts remains enigmatic. From the perspective of dynamical systems theory, such critical transitions occur upon inconspicuous perturbations in highly interconnected systems and can be modeled as mathematical bifurcations between … Continue reading Spotlight 2024 – Day2 – #1 | – Gregory LEPEU – The critical dynamics of hippocampal seizures
