A unifying framework for mean-field theories of asymmetric kinetic Ising systems

I’m happy to see published this new paper in collaboration with Amin Moosavi and Hideaki Shimazaki in Nature Communications. In this paper study and unify different kinetic mean-field methods in Ising models with the objective of developing tools for studying large data-sets from networks of neurons in non-equilibrium conditions and near critical and maximally fluctuating regimes. We propose a framework that integrates previo...  Read more

Critical integration in neural and cognitive systems: Beyond power-law scaling as the hallmark of soft assembly

I just published a new paper with Ezequiel Di Paolo in Neuroscience & Biobehavioral Reviews. Here we review the link of self-organized criticality and integrated information with ideas about soft assembly in neural and cognitive process. Studying the properties of power-law scaling processes as a in indicator of properties like soft-assembly, self-organization or interaction-dominant-dynamics is a suggest...  Read more

New website

Welcome to my new Jekyll website. I’ll migrate most of the content from the old one, which is still available at https://maguilera0.wordpress.com.

DIMENSIVE project

I’m happy to share that I have been granted a MSCA-IF grant to start a project at the University of Sussex in collaboration with Chris Buckley. The project aims to apply information-theoretic and inference methods to develop models of neural activity from zebrafish larvae in closed loop behavior, e.g. trying ...  Read more

Scaling Behaviour and Critical Phase Transitions in Integrated Information Theory

I just published a new paper exploring some of the ideas we initiated in our Integrated information in the thermodynamic limit (Aguilera & Di Paolo, 2019) paper. Here, I explore in detail many of the assumptions of Integrated Information Theory (specifically IIT 3.0) by computing integration in large kinetic Ising networks presenting a critical point. By combining a simpl...  Read more

Integrated information in the thermodynamic limit

Together with Ezequiel Di Paolo, we have just published a new paper in which we explore how integrated information scales in very large systems. The capacity to integrate information is crucial for biological, neural and cognitive processes and it is regarded by Integrated Information Theory (IIT) proponents as a measure of conscious activity. In this paper we compute (analytically and numerically) the value of IIT measures ($\Phi$) for a family of Ising models of infinite size. This is ex...  Read more

Adaptation to criticality through organizational invariance in embodied agents

I just published with Manuel Bedia a paper in Scientific Reports that results from an exploration of how tools from statistical mechanics could be used to model adaptive mechanisms. In this paper, we explore how adaptation to criticality could be used as a general adaptive mechanism in robots controlled by a neural network, using a simple mechanism that preserves a specific structure of correlations. This has in...  Read more

Rhythms of the Collective Brain: Metastable Synchronization and Cross-Scale Interactions in Connected Multitudes

I have recently published a new paper where we model social coordination in self-organized crowds social media, using data from the 15M movement in Spain:
