We examined if the repeatability of fMRI facial emotional processing in healthy participants (HCs) is affected by mood state changes and hypothesized that fMRI activation would be stable but may be influenced by mood state fluctuations. In a multi-site study, thirty-two HCs underwent emotion faces task (EFT) fMRI and completed a post-scan facial emotion rating and the Profile of Mood States (POMS) ∼ 12 weeks apart. FMRI data were processed using AFNI software. POMS and behavioral data were analyzed using repeated measures ANOVA and the sign test, as appropriate. Paired-samples t-tests, covarying for site, assessed fMRI responses for facial emotions (Happy, Fearful, Sad, Neutral) and Arousal. Intraclass correlation coefficient (ICC) examined repeatability of POMS and fMRI responses; regression analyses examined relationships between mood changes and fMRI activations. There were no significant differences between visits in POMS, EFT performance or post-scan ratings accuracy. POMS scores were stable (ICC ≥ 0.74). FMRI activation exhibited repeatability that was fair or better (ICC ≥ 0.4). EFT activation changes were not significantly related to mood state changes. Our results provide evidence for acceptable EFT fMRI test–retest reliability over 12 weeks, without significant influence of mood state variability.</div></div>","PeriodicalId":55331,"journal":{"name":"Brain and Cognition","volume":"186 ","pages":"Article 106283"},"PeriodicalIF":2.2,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143580578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Behavioral results showed significantly higher ratings for painful stimuli compared to non-painful ones. ERP analysis revealed that, under moral enhancement, pain stimuli elicited more negative N1 amplitudes and more positive P3 amplitudes. Time-frequency analysis indicated that moral enhancement inhibited theta band activity in response to painful stimuli. Functional connectivity analysis showed stronger connections in the frontal, right temporal, and occipital regions under moral enhancement and in the frontal, right temporal, and parietal regions when viewing painful stimuli. Additionally, machine learning results indicated that functional connections between the right temporal and parietal regions have significant negative predictive power for moral enhancement during painful stimuli.

Currently, the primary method of protection is the utilization of inflatable anti-G suit to address instances where blood is concentrated in the lower extremities. The inflatable air pressure of the anti-G suit varies in response to different overload conditions, which in turn affects the pilot’s sensory and brain loads. However, this change has not yet been fully explored. To investigate the neural effects of pressure from the anti-G suit under different degrees of overload, this paper employs a pressurized simulation methodology. The subjects’ brain state changes during the simulation are measured through electroencephalogram (EEG), and comparative calculations are performed using microstate and functional connectivity. The final results demonstrate that varying inflation levels of the bladder anti-G suit can influence the microstate and functional connectivity. The Duration, Coverage, Occurrence, and transition probability (TP) characteristics of microstate C demonstrated significant variance across three distinct levels of overload. The mean increase in Phase Locking Value (PLV) for overload 3 relative to the absence of overload was 13.8%, and the number of channel synchronizations underwent a transition from 7 to 62.</div></div>","PeriodicalId":55331,"journal":{"name":"Brain and Cognition","volume":"184 ","pages":"Article 106269"},"PeriodicalIF":2.2,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143147931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While previous research has touched on how personality traits influence malevolent creative behavior, the neural mechanisms involved remain underexplored. This study investigated the brain patterns associated with malevolent creative behavior and how these patterns are mediated by dark personality traits (Machiavellianism, narcissism, and psychopathy) and positive traits (internalization, symbolization, and honesty-humility). Our findings revealed that Machiavellianism mediated the relationship between the amplitude of low-frequency fluctuation (ALFF) in the left medial superior frontal gyrus (mSFG), pallidum (PAL), and middle temporal gyrus (MTG) and malevolent creative behavior, particularly in actions like hurting people or playing tricks. Psychopathy similarly mediated the link between the ALFF in the right orbital middle frontal gyrus (oMFG), right mSFG, left PAL, and left MTG and malevolent creative behavior. Additionally, Machiavellianism negatively mediated the relationship between the fractional ALFF (fALFF) of the left parahippocampal gyrus (PHG) and hurting people, as well as between the fALFF of the left inferior occipital gyrus (IOG) and playing tricks. The ALFF in the left mSFG and left MTG predicted playing tricks but also negatively predicted internalization and honesty-humility, which in turn reduced engagement in playing tricks. Finally, the fALFF of the left IOG negatively predicted playing tricks and positively predicted internalization, which again decreased playing tricks.

Specifically, this study investigated the role of premotor and prefrontal cortices, and sensory visual areas in preparatory activity preceding time-processing by electroencephalographic methods and analyzing the event-related potential (ERP). ERP components associated with motor (the BP), cognitive (the pN), and sensory readiness (the vN) were analyzed on 21 participants completing the two DRTs. The results support the involvement of all considered brain areas in temporal cognition but extend this information by indicating that these areas can be engaged during the preparation phase before the stimulus is delivered. Furthermore, the T-DRT requires strong anticipatory activity in the PFC likely serving as a moderator of upcoming motor responses.

The rising emotional salience of the discourses induced a negativity bias and extensive low-frequency band activation (delta and theta) across the scalp in response to emotional demands. High-frequency bands exhibited a plateau effect, indicating less cognitive involvement as the discourses progressed. In our opinion, a possible interpretation is that this effect could be due to habituation mechanisms or coping strategies. Autonomic results revealed significant variations in PVA, with higher levels during the first discourse preparation, indicating substantial cognitive effort. Despite increased emotional arousal, participants managed stress effectively, as evidenced by increased HRV during the speech stage.

Participants viewed images depicting object-tool pairs that were either mechanically consistent (<em>e.g.</em>, nail – steel hammer) or mechanically inconsistent (<em>e.g.</em>, scarf – steel hammer). These pairs were situated on a metal plate atop a table, with a stripped electrical cable in contact with the plate that could be plugged in or out from the electrical line, rendering the tools either electrified or not. Task-based functional connectivity revealed an interplay among specific left-brain regions – the middle temporal (MTG), inferior frontal (IFG), and supramarginal (SMG) gyri – during the processing of mechanical actions and physics principles, associating the activity of these areas with mechanical knowledge (SMG) and object-related semantic knowledge (MTG).
