Connectivity between the hippocampus and default mode network during the relief, but not elicitation, of curiositysupports curiosity-enhanced memory enhancements

This study investigates how neural networks like the dopaminergic-hippocampal, FPN, and DMN support curiosity and enhance memory, finding distinct patterns during curiosity elicitation and relief.

Hello, is that me you are looking for? A re-examination of the role of the DMN in off-task thought

The paper examines the role of the default mode network (DMN) in off-task thought by analyzing neural activity and self-reported experiences, finding no strong association with self or social content but suggesting a role in representing ongoing thought.

Salient images: Evidence for a component process architecture for visual imagination.

This study shows visual imagination involves interactions between primary visual cortex and the ventral attention network, particularly the right dorsolateral prefrontal cortex.

Isolated from input: Evidence of default mode network support for perceptually-decoupled and conceptually-guided cognition

The paper identifies brain regions in the default mode network that support stimulus-independent and conceptually-guided cognition, showing stronger responses to complex memory tasks than perceptual ones.

Scaffolding imagination: A role for medial frontal cortex in the expression of off-task thought

The paper investigates the neural basis of task-unrelated thought (TUT) and finds that medial prefrontal cortex activity correlates with TUT expression, distinguishing between language-related and memory-related domains.
