This study aimed to elucidate the mechanisms by which pain empathy modulates individual experiences, focusing on two primary questions: When individuals empathize with pain, do they attend more to the emotional content associated with pain or the nociceptive experience itself? How does lexical labeling modulate negative affect during pain empathy? In this EEG study, we employed a labeling paradigm divided into pain labeling, affect labeling and tool labeling to distinguish emotional content from the nociceptive experience of pain stimuli. We collected data from 39 participants and analyzed their EEG components and frequency-specific brain activity across the experimental conditions. Cross-frequency coupling analyses were conducted to uncover the mechanisms by which pain empathy modulates emotional responses. Our findings revealed that compared to pain labeling and tool labeling, affect labeling more effectively reduces the negative affect associated with pain empathy. This was evidenced by the decreased amplitude of the P300 component and lower theta-band activity within the prefrontal cortex, predominantly during the later stages of labeling. Additionally, affect labeling was associated with enhanced theta-gamma phase-amplitude coupling, with theta phase modulation in the posterior parietal and sensorimotor cortices influencing prefrontal gamma-band activity. These results suggest that, during pain empathy, individuals allocate greater attentional and cognitive resources to the emotional aspects of pain. Thus, implicit regulation of pain empathy involves coordinated interactions across multiple brain regions.</div></div>","PeriodicalId":19299,"journal":{"name":"NeuroImage","volume":"310 ","pages":"Article 121161"},"PeriodicalIF":4.7,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143670472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is essential to develop accessible methods of enhancing cardiac vagal activity (CVA) to mitigate these adverse effects. We previously demonstrated that inhaling low-dose hypoxic gas (FIO₂: 13.5 %) for 10 min acts as a hormetic stressor, inducing a supercompensation effect in CVA post-hypoxia. Since CVA is a key mediator of brain-heart communication in that it influences executive functions by interacting with the left dorsolateral prefrontal cortex (L-DLPFC), increasing CVA may enhance cognitive ability. We hypothesized that acute low-dose hypoxia leads to enhanced executive function via CVA modulation. Twenty-six individuals participated in both normobaric hypoxia (NH; FIO₂: 13.5 %) and normoxia (NN; ambient air) conditions. CVA, measured through heart rate variability, was analyzed three times: pre-hypoxia/normoxia, hypoxia/normoxia, and post-hypoxia/normoxia. Executive function was assessed using the Stroop task before and after exposure, and prefrontal cortex activity during the task was monitored using multichannel functional near-infrared spectroscopy. A supercompensation of CVA occurred concomitantly with a reduction in heart rate following hypoxic gas inhalation. Stroop performance improved with increased task-related activation of the L<span>-DLPFC</span> in the NH condition. Causal mediation analysis revealed that the post-hypoxia enhancement of CVA mediated improvements in Stroop performance and increased L-DLPFC activation. These findings strongly support our hypothesis that the enhancement of CVA following hormetic hypoxic stress contributes to improved executive function, broadening the scope of neurocognitive approaches for effectively enhancing executive function.</div></div>","PeriodicalId":19299,"journal":{"name":"NeuroImage","volume":"310 ","pages":"Article 121139"},"PeriodicalIF":4.7,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143642153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multilinguals may exhibit unique age-related speech patterns depending on their language profiles. This study investigates the relationships between age-related differences in brain structure and multilingual speech across different languages, considering the effects of multilingual experience. An integrated measure of speech was calculated and used to reflect the overall speech quality, which was lower in older than younger adults. Native language speech (i.e., Cantonese) was better than non-native language speech (i.e., Mandarin), especially in older adults. More extensive use of multiple languages was associated with enhanced speech quality in both native and non-native languages. Age significantly impacts whole brain gray matter volume, which was lower in older than younger adults. The right middle temporal gyrus emerged as a critical region for speech in both languages in older adults.

Until recently it has been challenging to relate these behavioural states to the underlying neural mechanisms that generate them. Here, we acquired magnetoencephalograpy recordings and contemporaneous, dense behavioural data from participants performing an engaging task (Tetris) that required rapid, strategic behavioural responses over the period of an entire game. We asked whether it was possible to infer the presence of distinct behavioural states from the behavioural data and, if so, whether these states would have distinct neural correlates. We used hidden Markov Modelling to segment the behavioural time series into states with unique behavioural signatures, finding that we could identify three distinct and robust behavioural states.

The objective of this cross-sectional study was to investigate the association between anxiety and pain ratings with levels of total choline, glutamate and GABA in brain regions known to be involved in anxiety and emotional experience of pain, specifically pregenual anterior cingulate cortex (pgACC) and dorsal anterior cingulate cortex (dACC). The levels of the neurotransmitters/metabolites were measured using GABA-edited Mescher–Garwood PRESS for GABA measurements, with the OFF-sequence measurements for total choline (tCho) and Glx (combined glutamate + glutamine). The total choline (tCho) signal in our analysis included glycerophosphocholine (GPC) and phosphocholine (PC), which is consistent with standard practices in MRS studies. This approach ensures a robust estimation of tCho concentrations across participants. The study collected data from 38 participants (17 males and 21 females). The analysis revealed a significant correlation between anxiety ratings before a standardized pain provocation and the rated pain unpleasantness during the pain provocation. tCho correlated negatively with these parameters in pgACC. A linear regression analysis indicated that tCho levels in pgACC have a significant negative association with anxiety and perceived pain when controlling for age, depressive symptoms, and alcohol and tobacco intake. We also found that sex significantly moderates the relationship between pgACC choline levels and pain unpleasantness. The study suggests that levels of choline, an essential precursor of acetylcholine, are associated with anxiety and perceived pain. These levels may influence how Glx and GABA contribute to affective pain experiences by modulating the balance between excitatory and inhibitory signals. However, future research is needed to identify the mechanisms involved. Furthermore, the study indicates that sex is a significant factor in this relationship, with lower choline levels being associated with higher pain ratings in females but not in males. This highlights the significance of addressing sex as a biological factor in pain research to better understand the different responses to treatments and to facilitate the development of more effective interventions in the future.</div></div>","PeriodicalId":19299,"journal":{"name":"NeuroImage","volume":"310 ","pages":"Article 121153"},"PeriodicalIF":4.7,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143657889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, particular diffusion parameters of the used dMRI approaches stood out in explaining some important phenotypes known to correlate with general human health outcomes. A multi-compartment Bayesian dMRI approach provided the strongest WM associations with age, and together with diffusion tensor imaging, the largest accuracy for sex-classifications. We find a similar pattern of metric and tract-dependent asymmetries across datasets, with stronger asymmetries in ABCD data. The magnitude of WM associations with polygenic scores as well as PP depended more on the sample, and likely age, than dMRI metrics.
