Article Synopsis
- The study investigates how changes in brain activity affect the ability to perform complex tasks, highlighting that poor flexibility in these brain dynamics can lead to cognitive difficulties, such as attention challenges and behavioral adjustments.
- It proposes a new framework that connects cognitive effort during task performance with EEG patterns by identifying discrete brain states and employing optimal transport theory.
- The approach is validated using data from the Stroop task, showing that higher cognitive effort incurs more neurological "costs," and emphasizes a fresh, data-driven way to understand cognitive effort in the brain.
Unraveling the mesoscale organization induced by network-driven processes.

Complex systems are characterized by emergent patterns created by the nontrivial interplay between dynamical processes and the networks of interactions on which these processes unfold. Topological or dynamical descriptors alone are not enough to fully embrace this interplay in all its complexity, and many times one has to resort to dynamics-specific approaches that limit a comprehension of general principles. To address this challenge, we employ a metric-that we name Jacobian distance-which captures the spatiotemporal spreading of perturbations, enabling us to uncover the latent geometry inherent in network-driven processes.

Applying a scaling analysis of neural oscillations to address this question, we show that newborns' electrophysiological activity exhibits increased long-range temporal correlations after stimulation with speech, particularly in the prenatally heard language, indicating the early emergence of brain specialization for the native language.
