Brain-thought states during movie-watching reflect shared sensory anchors and film- and person- specific processes in association cortex

This study examines brain-thought relationships during movie-watching, finding that sensory-related neural signatures are consistent across films, while memory-related processes vary with context and modeling approaches.

Lesion-Gradient Mapping in Semantic Aphasia: Comparisons of Observed and Simulated Effects of Stroke on Connectivity Gradients

This study shows that changes in functional connectivity gradients after stroke can explain semantic aphasia deficits, and these changes can be simulated from structural MRI data.

The stability of thought: using experience sampling and brain imaging to determine the contextually bound nature of human cognition.

The paper examines the relationship between task context, thought patterns, and neural activity, finding that thought reliability varies with task context and is associated with MDN activity.

Unsupervised identification of internal perceptual states influencing psychomotor performance

The paper identifies distinct behavioural states during a complex task using hidden Markov modelling and links them to neural correlates like occipital alpha power.

Memory control deficits in the sleep-deprived human brain

This study shows that sleep deprivation disrupts prefrontal inhibition of memory retrieval, linking sleep loss to intrusive memories through impaired neural circuits.

Mapping patterns of thought onto brain activity during movie-watching

The paper develops a method to map thought patterns onto brain activity during movie-watching and finds sensory and association cortex play key roles in engagement and distraction.

Experience sampling reveals the role that covert goal states play in task-relevant behavior.

This study uses experience sampling to examine covert goal-relevant states during task performance, finding that fronto-parietal network activity is linked to better task performance.

Exploring patterns of ongoing thought under naturalistic and task-based conditions

The paper examines how ongoing thought patterns vary across tasks and individual affective styles, identifying four patterns and their contextual and personal influences.

Interactions between the neural correlates of dispositional internally directed thought and visual imagery

The paper investigates neural correlates of dispositional internally directed thought and visual imagery, finding associations between brain networks and self-reported traits.

The psychological correlates of distinct neural states occurring during wakeful rest

This study identifies two distinct neural states during wakeful rest using machine learning and links them to specific psychological features like problem-solving and negative rumination.

Missing the forest because of the trees: Slower alternations during binocular rivalry are associated with lower levels of visual detail

The paper links variations in binocular rivalry duration to white matter organization and reports of external visual detail.

Distinct patterns of thought mediate the link between brain functional connectome and psychological well-being

The paper identifies two thought patterns linked to functional connectomes and psychological well-being in a neurotypical cohort.

Neural dynamics at rest associated with patterns of ongoing thought

This study links neural state transitions during wakeful rest to patterns of ongoing thought and well-being.

Stable between-subject statistical inference from unstable within-subject functional connectivity estimates

The paper proposes a permutation testing method to improve statistical inference from noisy functional connectivity estimates by combining results across replications.

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.
