Cortical reinstatement of causally related events sparks narrative insights by updating neural representation patterns

The paper investigates how neural patterns representing causally related past events are reinstated and updated in the brain during moments of narrative insight.

Neural dynamics of updating social impressions during movie watching

The paper investigates how the brain updates social impressions during movie watching, finding that neural synchrony and insight moments drive impression changes.

Task-induced topological and geometrical changes in whole-brain dynamics predict cognitive individual differences

This paper develops a computational framework to model how task-induced changes in brain dynamics relate to cognitive individual differences using rsfMRI and tfMRI data.

Geometry of neural dynamics along the cortical attractor landscape reflects changes in attention

The paper models neural dynamics on an attractor landscape to show how attentional states and contexts alter the geometry of brain activity trajectories.

A neural network with key-value episodic memory retrieves and organizes memories based on causal event structures

Ongoing thoughts at rest reflect functional brain organization and behavior

This study shows that ongoing thoughts during rest are reflected in brain connectivity and predict individual behavioral differences.

High performers demonstrate greater neural synchrony than low performers across behavioral domains

The paper examines brain-behavior relationships using fMRI data and finds that neural similarity does not always correlate with behavioral similarity across different domains.

Dynamic functional connectivity encodes generalizable representations of emotional arousal across individuals and situational contexts

The paper identifies a generalizable arousal representation from dynamic functional connectivity across different individuals and movie-watching contexts, while finding no evidence of a generalizable valence representation.

Large-scale neural dynamics in a shared low-dimensional state space reflect cognitive and attentional dynamics

The paper shows that large-scale neural dynamics in a shared low-dimensional state space reflect cognitive and attentional states during tasks and naturalistic conditions.

Cognitive and Neural State Dynamics of Story Comprehension

This study examines cognitive state dynamics during story comprehension and finds that the brain enters functionally integrated states with increased DMN activation during moments of understanding.

Neural signatures of attentional engagement during narratives and its consequences for event memory

This study links fluctuations in narrative engagement to brain coactivation patterns and shows that neural signatures of engagement predict later memory recall.
