Welcome to the Virtual Poster area! Presentations can be classic static posters, short slideshows or even short video-talks.

Posters are on view all time. All presentations will remain available on this page even after the end of the conference. From Wednesday November 6th to Friday November 15th included you will be able to post your questions in the comment forum below each presentation. The presenters will leave their answer, answering in threads and you can choose to receive a notification when an answer is posted to your question.

Presenters are free to propose in the forum and in the conference chat self-organized video-presentations with interested attendants, sharing zoom links to private external meetings. Moments suitable for organizing these presentations are the coffee and lunch break slots, and, particularly, the long break between 15h30 and 16h30 on Thursday November 7 .

The list below will be populated with submitted virtual posters starting from the first day of the conference… Stay tuned!

Poster 2024#15 – Cintia Ferreira da Silva – Emotions and Brain Connectivity: Phase, Coherence, and Directionality

Emotions play a fundamental role in modulating brain activity and influencing perception, cognition, and action. However, the underlying connectivity mechanisms associated with different emotional states remain poorly understood. The objective of this study is to investigate human brain connectivity in response to emotional stimuli of happiness, anger, sadness, fear, and neutral stimuli, using electroencephalogram (EEG)…

Poster 2024#14 – Edson Noia – Phenomenological Renormalization Group analysis on population dynamics of the primary visual cortex under chronic stress

Exploring how stress impacts sensory processing, particularly at the level of neuronal population dynamics in the primary sensory cortex, remains a relevant yet under-investigated area. In this study, we applied the Phenomenological Renormalization Group (PRG) method to analyze recordings from large neuronal populations in the primary visual cortex (V1) of urethane-anesthetized female rats subjected to…

Poster 2024#13 – UnCheol Lee – Proximity to Explosive Synchronization Determines Trajectory of Network Recovery after Neural or Economic Crisis

Delayed recovery from a crisis can cause damage to a system. However, the mechanism by which systems efficiently recover from crises is unknown. Here, we show that the strength of conditions for explosive synchronization, i.e., the proximity of a complex dynamical network to a first-order phase transition, determines whether a perturbed network will recover quickly…

Poster 2024#12 – Derek Newman – Complexity, Entropy and Criticality: Assessing States of Consciousness Under Anesthesia

The assessment of consciousness using neuroimaging has increasingly focused on brain complexity and entropy, intrinsic features of critical systems that provide insight into transitions between dynamic regimes. Complexity measures have varied relationships to entropy, such as positively linear (type 1) or parabolic (type 2) interactions. By combining a type 2 complexity measure with entropy, we…

Poster 2024#11 – Sue Lam – KTH neuron map based: Optimal input reverberation at criticality

The critical point is crucial for information processing in the healthy brain. Thus, studies show the presence of a critical state with power-law distributed neuronal avalanches and other scaling properties, breaking the separation between an inactive state and a synchronized epileptic-like state, relating epileptic state and synchronization transition [1].In our study using the KTH model…

Poster 2024#9 – Braden A. W. Brinkman – A non-perturbative renormalization group analysis of stochastic spiking networks

Understanding which features of network architecture are most important for shaping the collective activity patterns of neural circuits is a major goal of theoretical neuroscience. For example, what network properties influence critical exponents in neural circuits at critical points? Answering this question with theory requires tools from the renormalization group, which to date have not…

Poster 2024#8 – Sam Sooter – Cortex deviates from criticality during action and deep sleep: a temporal renormalization group approach

The hypothesis that the brain operates near criticality explains observations of complex, often scale-invariant, neural activity. However, the brain is not static– its dynamical state varies depending on what an organism is doing. Neurons often become more synchronized (ordered) during unconsciousness and more desynchronized (disordered) in highly active awake conditions. Are all these states equidistant…

Poster 2024#7 – Renée Tung – Inhibitory circuit synchronization drives working memory dynamics

Recent advances in human intracranial recordings have significantly deepened our understanding of complex cognitive functions like working memory (WM) at the circuit level. While single-neuron analyses, primarily within the medial temporal lobes, have elucidated how individual neurons contribute to memory computation, the role of local field potential (LFP) dynamics in complementing single-unit activity during WM…

Poster 2024#6 – Michael Angyus – A spike in entropy precedes the mismatch negativity: linking entropy and prediction error

Predictive coding suggests that the brain minimizes free energy through the accurate prediction of sensory stimuli. While not mathematically identical, some research has suggested that information content of a brain signal can act as a proxy for free energy. Measures such as Shannon’s entropy and Shannon’s entropy rate may therefore be combined with experimental paradigms…

Poster 2024#4 – Gustavo Gama Cambrainha – With or without scaling? Exploring criticality across brain areas during task performance

The critical brain hypothesis posits that neural systems operate near a critical phase transition, potentially optimizing computation and information processing. However, the precise relationship between criticality and performance in living systems remains a mystery. In this companion study to “Neuronal Scaling in the Mouse Visual Cortex During a Visual Recognition Task,” we extend our investigation…

Poster 2024#3 – Alina Suleimanova – Phenotype discovery using personalized generative whole-brain modeling

The brain is tuned to operate near a critical phase transition between disordered and ordered states by control parameters such as the balance between functionally excitatory and inhibitory neurotransmission. Deviations from this balance are linked to multiple brain disorders making the emergent dynamics a potential mechanistic biomarker. Indeed, neurophysiological biomarkers appear promising for applications in…

Poster 2024#2 – Vladislav Myrov – Hierarchical whole-brain modeling of critical synchronization dynamics in human brain

Whole-brain computational modeling has become increasingly important for understanding the systems-level mechanisms governing the dynamics of large-scale brain activity. Brain dynamics, characterized by synchronization and criticality of neuronal oscillations, are fundamental to cognitive functions. The remarkable inter-individual variability in observables neuronal synchronization dynamics in vivo has been attributed to both individual operating point locations in…

Poster 2024#1 – Dimitrios Chalkiadakis – The connectivity of minimal neuronal motifs could explain gamma-leading theta interactions in recordings of synchronous neural activity

In the brain, synchronous activity is detected as oscillations at different frequencies. Experimental data from the hippocampus and neocortex link Phase-Amplitude Cross Frequency Coupling (PAC), where the amplitude of fast gamma oscillations aligns with the phase of slower theta/alpha waves, to cognitive functions like attention, learning and navigation. Traditionally, this mechanism was thought to be…
