When the male subject rats were allowed to interact with a pair consisting of a naïve stimulus rat and a shocked stimulus rat that had received foot shocks immediately before testing, they showed the biased social interaction toward shocked stimulus rats. Findings in the literature suggest roles for the oxytocin and other neuromodulatory systems in this biased interaction. However, the roles of the vasopressin, dopamine, and opioid systems remain unclear. Here we examined the effects of intraperitoneal administration of atosiban (an oxytocin receptor antagonist), SR49,059 (a vasopressin V1a receptor antagonist), haloperidol (a dopamine D2 receptor antagonist), naloxone (an opioid receptor antagonist), or vehicle, on this biased interaction. The vehicle-treated subjects showed longer interaction times toward shocked stimulus rats than toward naïve stimulus rats. This bias was abolished by atosiban, SR49,059, or haloperidol, whereas the naloxone-treated subjects retained the bias. These results suggest that oxytocin, vasopressin V1a, and dopamine D2 receptors, but not opioid receptors, contribute to biased interaction toward stressed conspecifics. Moreover, the naloxone-treated subjects showed an increased total interaction time, suggesting increased sociality. These findings contribute to a more comprehensive understanding of the neuromodulatory mechanisms underlying stress identification.","PeriodicalId":49511,"journal":{"name":"Social Neuroscience","volume":" ","pages":"1-9"},"PeriodicalIF":2.0,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149117606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Masters and Johnson described sensations signaling approaching orgasm, but the neural basis of this anticipatory awareness remains unexplained.The present article terms this period Erotic Intimation. It begins at the proposed Intimation threshold, when bottom-up sexual information captures attention, and continues while orgasm feels increasingly imminent, but escalation remains redirectable. Although sexual-neuroscience studies have documented cerebellar activity before and during orgasm, they have not examined its possible predictive contribution to felt orgasmic imminence. Integrating this evidence with predictive processing, the framework proposes that cerebellar prediction interacts with salience and frontal systems as precision weighting increases the influence of bottom-up information while top-down regulation remains more influential. This account extends the interpretation of pre-orgasmic cerebellar activity beyond motor preparation to cognitive-affective anticipation. Epileptic aura provides a clinical boundary comparison, with orgasmic aura offering the closest phenomenological parallel because the feeling that orgasm is coming can arise from activity that is already ictal. The framework identifies Erotic Intimation as a distinct neuroscientific target and offers a theoretical explanation of how this anticipatory awareness may arise.","PeriodicalId":49511,"journal":{"name":"Social Neuroscience","volume":" ","pages":"1-5"},"PeriodicalIF":2.0,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148876373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty-nine participants completed an adapted Balloon Analogue Risk Task with financial (monetary rewards) and social (gifts for children) incentive conditions. Behavioral data show that participants demonstrate less risk-seeking behavior in the social compared to financial condition. Neuroimaging results revealed both domain-general and domain-specific components of risk processing. A conjunction analysis of both incentive conditions identified a common neural network across both incentive types, including bilateral striatum, dorsal anterior cingulate cortex, and left insular cortex, supporting theories of domain-general risk processing mechanisms. Contrasting both reward conditions revealed significantly stronger activation in the right inferior parietal lobule during financial compared to social risk-taking, thus indicating a neural substrate for domain-specific risk preferences.

Although casual touch has been assumed to affect emotion and decision-making through a parallel mechanism, this has been challenging to test: How does touch affect learning to associate trust with people? A social version of the Iowa Gambling Task was designed by replacing cards with faces and associating these with tactile stimuli and economic outcomes. We measured how learned associations affected 1) choice preference during the Social Gambling Test (SGT), 2) face preferences in a subsequent oddball EEG task featuring SGT-stimuli; 3) choice adjustment in a final SGT with economic outcomes being reversed. Contrary to predictions, no initial bias toward touch-associated faces was observed. However, event-related potentials during the oddball task showed preferential processing toward disadvantageous/touch-associations, with early P3 component amplification. This effect presaged preference adjustments toward touch-associated faces in the second SGT when reward contingencies were reversed. Touch therefore did not directly produce trust but modified decision-making indirectly. We argue that tactile events and emotional outcomes are integrated within episodic memory and retrieved when risks require adaptation. We relate this interpretation to attachment theory, which likely highlights the relation between stressful uncertainty and tactile behavior.","PeriodicalId":49511,"journal":{"name":"Social Neuroscience","volume":" ","pages":"190-204"},"PeriodicalIF":2.0,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148406597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Theory of mind is a complex construct, but age deficits are generally measured in a single domain, overlooking how older adults engage multiple theory of mind processes concurrently and spontaneously. The current work used neuroimaging to characterize the neural mechanisms associated with older adults' deficits in concurrent theory of mind judgments (awkwardness, deception) during a movie-watching task. 102 older adults (MAge = 73.5, SD = 6.6) and 110 young adults (MAge = 21.75, SD = 4.2) passively viewed a mockumentary television show while undergoing functional magnetic resonance imaging. Continuous ratings of awkwardness and deception were collected from an independent sample of young and older adults and used as parametric regressors. Across both judgment types, young adults had stronger activation in the dorsomedial prefrontal cortex, a region broadly implicated in theory of mind. Moreover, higher activation in the dorsomedial prefrontal cortex in response to deception and awkwardness was associated with older adults' higher theory of mind performance on an unrelated task. The brain activity involved in decoding concurrent mental states may provide unique insight into older adults' theory of mind deficits.","PeriodicalId":49511,"journal":{"name":"Social Neuroscience","volume":" ","pages":"205-220"},"PeriodicalIF":2.0,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13566915/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148632408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Before each interaction, participants' DM orientations were assessed, and dyads' orientation shift was classified according to whether one or both members changed orientation between the dilemmas (single-shift vs. dual-shift dyads). Interpersonal dissimilarity was quantified through Euclidean Distance (EuDist) across EEG frequency bands and Skin Conductance Level (SCL), Heart Rate (HR), HR Variability (HRV). Delta and gamma bands showed greater inter-brain dissimilarity in frontal than temporo-central and parieto-occipital regions, indicating region-specific recruitment for moral negotiation.

About perspective, autonomic results revealed greater inter-individual dissimilarity during first- than third-person perspective across SCL, HR, and HRV.

Distinct modes of reward, such as drug and social, may rely on different dopamine release patterns in the mesolimbic pathway. We investigated the relationship between social reward behaviors and dopamine release elicited by phasic and tonic stimulation patterns in C57BL/6J mice. Cocaine (10 mg/kg, ip) was administered during dopamine recordings to assess drug-evoked dopamine release in relation to social reward behaviors. Social conditioned place preference was used to assess social reward, and in vivo fixed potential amperometry was used to measure nucleus accumbens dopamine release. Additional measures included the frequency and duration of social interactions during conditioning sessions. No relationship was found between baseline (pre-cocaine) dopamine and social place preference in either sex. However, in males, social place preference negatively correlated with cocaine-induced phasic dopamine release, indicating that increased social motivation was associated with a reduced phasic dopaminergic response to cocaine. In contrast, greater novel social interaction was associated with increased baseline dopamine elicited by tonic stimulations. These relationships were not observed in females. Overall, these findings suggest distinct, sex-dependent roles for phasic and tonic dopamine release in mediating social reward.","PeriodicalId":49511,"journal":{"name":"Social Neuroscience","volume":" ","pages":"141-152"},"PeriodicalIF":2.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147786905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using event-related potentials, the neural processing of social exclusion has been explicated and is often linked to reductions in frontal slow wave (FSW) amplitude. This study examined FSW amplitude as elicited by the social exclusion game, Cyberball, to investigate the neural mechanisms of social exclusion processing in 43 fathers with and without histories of IPV use. We further investigate group differences in self-reported ostracism distress and emotional clarity across IPV-using and control fathers. IPV-using fathers displayed significantly lower exclusion evoked FSW amplitude, possibly reflecting stress-induced disruptions to mentalizing. Additionally, IPV-using fathers reported no significant differences in ostracism distress but increased difficulties in emotional clarity. Overall, findings suggest that IPV-using fathers display a profile of heightened neural sensitivity to social exclusion and a reduced ability to access their emotional states.
