Processing pathways between sensory and default mode network (DMN) regions support recognition, navigation, memory but their organisation is not well understood. We show that functional subdivisions of visual cortex DMN sit at opposing ends parallel streams information processing visually-mediated semantic spatial cognition, providing convergent evidence from univariate multivariate task responses, intrinsic structural connectivity. Participants learned virtual environments consisting buildings populated with objects, drawn either a single category or multiple categories. Later, they made context decisions about these objects during magnetic resonance imaging. A lateral ventral occipital to frontotemporal pathway was primarily engaged by judgements, while medial temporal supported judgements. These had distinctive locations in connectivity space: the both further unimodal systems more balanced auditory-motor compared pathway. When could be integrated (in containing category), intersection responded, suggesting interact levels cortical hierarchy produce coherent memory-guided cognition.

Abstract Rumination is a cognitive style characterized by repetitive thoughts about one’s negative internal states and common symptom of depression. Previous studies have linked trait rumination to alterations in the default mode network, but predictive brain markers are lacking. Here, we adopt modeling approach develop neuroimaging marker based on variance dynamic resting-state functional connectivity test it across 5 diverse subclinical clinical samples (total n = 288). A whole-brain with dorsomedial prefrontal cortex (dmPFC) emerges as generalizable datasets. refined consisting most important features from virtual lesion analysis further predicts depression scores adults major depressive disorder ( 35). This study highlights role dmPFC provides for rumination.

The contents and dynamics of spontaneous thought are important factors for personality traits mental health. However, assessing thoughts is challenging due to their unconstrained nature, directing participants’ attention report may fundamentally alter them. Here, we aimed decode two key content dimensions thought—self-relevance valence—directly from brain activity. To train functional MRI-based predictive models, used individually generated personal stories as stimuli in a story-reading task mimic narrative-like ( n = 49). We then tested these models on multiple test datasets (total 199). default mode, ventral attention, frontoparietal networks played roles the predictions, with anterior insula midcingulate cortex contributing self-relevance prediction left temporoparietal junction dorsomedial prefrontal valence prediction. Overall, this study presents internal emotions, highlighting potential decoding thought.

Interdisciplinary research has proposed a multifaceted view of human cognition and morality, establishing that inputs from multiple cognitive affective processes guide moral decisions. However, extant work on largely overlooked the contributions episodic representation. The ability to remember or imagine specific moment in time plays broadly influential role behavior.

Abstract Although central to well-being, functional and dysfunctional thoughts arise unfold over time in ways that remain poorly understood. To shed light on these mechanisms, we adapted a “think aloud” paradigm quantify the content dynamics of individuals’ at rest. Across two studies, external raters hand coded each thought computed dynamic metrics spanning duration, transition probabilities between affective states, conceptual similarity time. Study 1 highlighted paradigm’s high ecological validity revealed narrowing scope following more negative content. 2 replicated 1’s findings examined individual difference predictors trait brooding, maladaptive form rumination. individuals, increased brooding was linked rated as negative, past-oriented self-focused. Longer shorter positive were also apparent increased, well tendency shift away from stronger thoughts. Importantly, explained independent variance, accounting for third variance brooding. These results uncover real-time cognitive signature rumination highlight predictive think aloud applied resting state cognition.

How do thoughts arise, unfold, and change over time? Are the contents dynamics of everyday thought rooted in conceptual associations within one's semantic networks? To address these questions, we developed Free Association Semantic task (FAST), whereby participants generate dynamic chains response to seed words that vary valence. Ninety-four adults from a community sample completed FAST additionally described rated six their most frequently occurring thoughts. Text analysis valence ratings revealed similarities thematic affective content between concept recurrent autobiographical Dynamic analyses individuals higher rumination were more strongly attracted negative spaces likely remain there longer. Overall, findings provide quantitative evidence may act as scaffold for complex thoughts, less ruminative mirror maladaptive repetitive daily life.
