Abstract The role of oxytocin (OT) in social behavior and brain networks has been widely documented. However, the effect OT on association between functional connectivity (FC) is yet to be comprehensively explored. In this study, using a face-perception task multiple connectome-based predictive (CPM) models, we aimed to: 1) determine whether could enhance behavioral performance, resting-state (rsFC), task-state (tsFC), 2) if so, enhancing triangular association. We found that both rsFC tsFC independently significantly predict performance group, but not placebo (PL) group. addition, correlation coefficient was substantially higher group than PL strength these associations partly explained by altering brain’s FCs related cognition resting states, mainly regions such as limbic system, prefrontal cortex (PFC), temporal poles (TP), temporoparietal junction (TPJ). Together, results suggest neuropeptides can increase consistency individual differences different modalities (e.g., level data).

Abstract Differences in brain structure and functional structural network architecture have been found to partly explain cognitive performance differences older ages. Thus, they may serve as potential markers for these differences. Initial unimodal studies, however, reported mixed prediction results of selective variables based on features using machine learning (ML). the aim current study was investigate general validity from imaging data healthy adults.

The default mode network (DMN) is intricately linked with processes such as self-referential thinking, episodic memory recall, self-projection, and understanding the mindset of others. Over recent years, there has been a surge in examining its functional connectivity, particularly antagonistic relationship frontoparietal networks (FPN) involved top-down attention, executive function, cognitive control. Notably, DMN demonstrates an anti-correlated connection FPN Dorsal Attention Network (DAN), leading to deactivation when one's attention turned towards external environment. fluidity switching between these internal modes processing—highlighted by this connectivity—has proposed indicator health mediated salience (SAL).

Abstract Mind wandering is typically characterized as a failure of attentional control, yet despite age-related executive function deficits, older adults report less mind than younger during cognitive tasks and in daily life. Self-reported episodes usually result similar behavioral detriments (e.g., greater RT variability, more task errors). However, the relatively few studies investigating neural correlates aging have revealed mixed findings, possibly because they rely on infrequent thought probes and, therefore, trials for analyses. In current study, we propose method to recover data by categorizing from commonly used sustained attention response according variability. Behavioral (n = 49 younger; n 40 older) that compared with adults, reported fewer episodes, but showed impacts thereof. Furthermore, both age groups, subjective reports predicted objective sorting into “on-” “off-task” Using these objectively sorted trials, investigated two EEG measures (diminished P1 P3 amplitude) 26 24 adults. Although did not differ between on- off-task either group, was diminished groups (albeit significantly adults) suggesting preserved perceptual reduced higher-order processing periods groups.
