Towards a scalable effective connectivity estimation in fMRI

Characterizing directed connections between brain regions is fundamental for understanding the brain’s network organization and how it supports cognitive processes. However, a reliable methodology allowing assessment of effective connectivity (EC) at the whole-brain level and across high-resolution parcellations has re...

Cracking the predictive stability code: dual trial-by-trial spatio-temporo-spectral dynamics of task representation directional tuning by Bayesian conflict expectations

Cognitive stability, or task focus, enables goal-directed behavior through representational dynamics: by prioritizing task-relevant representations over competing task-irrelevant ones. Beyond corrective reactive mechanisms operating after conflict arises, stability can be deployed predictively through the statistical l...

Waves of control: An ER(S)P study to explore the neural dynamics of proactive and reactive stability.

Cognitive stability, the ability to maintain task focus while facing distractions, is a core component of cognitive control. According to the Dual Mechanisms of Control model, stability can be implemented proactively, through anticipatory goal maintenance, or reactively, through transient, conflict-triggered adjustment...
