In such solving, shifting from an incorrect representation imposed by constraints to a correct representation through constraint relaxation is critical. Prior research compared brain activity when constraint relaxation and representation change occurred versus when they did not occur, but neural activity before and after such changes within trials has remained underexplored. This study examines neural correlates of problem solving progress, focusing on transitions from impasse—defined by an incorrect, constrained representation—to the state immediately preceding the ‘Aha!’ moment when constraints relax and correct representation emerges. Functional near-infrared spectroscopy (fNIRS) monitored brain activity during a slot machine task. Task performance and eye movement data identified the representations adopted by participants and whether constraint relaxation occurred. Participants were categorized into a success group, which reached the solution, and a failure group, which did not. In the success group, the state just before ‘Aha!’ showed increased oxygenated hemoglobin in the right dorsolateral prefrontal cortex (DLPFC) and superior temporal gyrus (STG) compared with the impasse state. In contrast, the failure group showed increased activity in the right angular gyrus. These results suggest that right DLPFC activation supports constraint relaxation via executive function and working memory, and right STG activation facilitates the transition to a new representation. Integrating fNIRS measures of right DLPFC/STG activation with eye tracking indices of saccade direction shifts enables detection of constraint relaxation preceding the ‘Aha!’ moment.</div></div>","PeriodicalId":8823,"journal":{"name":"Behavioural Brain Research","volume":"495 ","pages":"Article 115813"},"PeriodicalIF":2.3,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145032542","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}

There is some limited evidence that rats exhibit similar patterns during Pavlovian conditioning. To substantiate this model, we tested the hypothesis that introducing light and auditory distractors would disproportionately impair the signal detection performance of ST rats, given their propensity for bottom-up attention processing, as opposed to GT rats, who rely more on top-down strategies. To this end, we assessed detection performance in 86 Long-Evans rats by introducing both visual and auditory distractors of varying intensities. This approach aimed to investigate the limits of attentional control among ST, GT, and IN rats across six variants of a sustained attention task. Although distractors impaired performance, contrary to initial expectations, the extent of this impairment varied across phenotypes and tasks, indicating a more nuanced relationship between attentional mechanisms and susceptibility to distractions than previously posited. The present results suggest the occurrence of a complex interplay of attentional mechanisms that may not align completely with the ST/GT dichotomy as traditionally presented. These findings have potential implications for understanding individual differences in attentional control and susceptibility to distractions, which could relate to addiction vulnerability.</div></div>","PeriodicalId":8823,"journal":{"name":"Behavioural Brain Research","volume":"495 ","pages":"Article 115800"},"PeriodicalIF":2.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145013799","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}

Despite conventional treatments such as cognitive behavioral therapy and medications like disulfiram and naltrexone, the majority of patients do not achieve adequate relief due to the multifactorial nature of this disorder, including mental health issues and neuroadaptive changes. Recent studies demonstrated that chronic alcohol consumption results in the disruption of both the production and signaling of endogenous agmatine, a neuromodulator synthesized from L-arginine. Agmatine modulates the neurotransmitter systems, particularly at NMDA and imidazoline sites, which are associated with neuroinflammation and neuroplasticity. Moreover, in preclinical models, altered agmatine metabolism is related to changes in alcohol seeking behavior, highlighting its potential as a novel therapeutic candidate. Furthermore, agmatine may mitigate the behavioral and biochemical effects of alcohol-induced neurotoxicity, indicating its potential role in improving tolerance management and withdrawal symptoms. Integration of agmatine into a multimodal treatment strategy could lead to comprehensive personalized interventions in patients with AUD, addressing both neurochemical imbalances and the psychosocial complexity associated with this disorder. Thus, this review explores the potential of agmatine in addressing psychological factors underlying AUD, offering a novel and optimistic treatment option for advancing future therapeutic approaches.
