Using the Remember/Know self-reference paradigm and event-related potentials (ERPs) technology, we manipulated response time and cognitive load to dissociate intuitive from analytical processing. Results showed that, under analytical processing conditions, maternal negative trait words elicited a stronger N400 component, indicating a positive bias in the evaluation of mothers, while self-negative trait words evoked a stronger LPP component, reflecting a negative processing bias toward self-related traits. Under intuitive processing conditions, individuals showed no evaluative bias toward their mothers, whereas self-positive trait words triggered enhanced N200 and N400 components, demonstrating a negative bias in self-evaluation. The modesty effect may explain the negative bias in self-evaluation during intuitive processing. The tendency to defend mothers' evaluations may be attributable to the emotional bond formed through long-term maternal parenting in collectivistic cultures.</p>","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":"1835-1850"},"PeriodicalIF":3.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147693398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While neurotransmitter release and receptor signaling during memory reactivation are known to trigger memory destabilization, the underlying regulatory networks and dynamic interactions remain unclear. Existing studies often examine neurotransmitters in isolation, lacking a unified framework. This review introduces a novel integrative framework that organizes existing evidence on neurotransmitter-mediated memory destabilization around novelty and prediction error (PE) signaling. By synthesizing experimental findings across dopamine (DA), norepinephrine (NE), acetylcholine (ACh), the glutamatergic/GABAergic systems, and the endocannabinoid system, we analyze how PE and novelty engage distinct yet interacting neural pathways. Integrating experimental data and theoretical concepts from multiple systems, we propose the PE-Novelty-Neurotransmitter Network-a unified framework explaining how multimodal neurotransmitter co-release across the midbrain-locus coeruleus-cortex circuit dynamically regulates the balance between memory stability and flexibility. This review addresses diverse memory types, with a focus on maladaptive memories, while also discussing emotional and nonemotional memories. It further discusses potential clinical implications, particularly how neuromodulatory process related to PE and novelty may inform strategies for modifying maladaptive memories and enhancing cognitive flexibility. By bridging mechanistic insights with translational considerations, this work establishes a unified framework for understanding memory plasticity and informs future efforts to translate basic neuroscience into therapeutic contexts.</p>","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":"1369-1392"},"PeriodicalIF":3.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147845693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We systematically examined ASD-related changes in structural-functional (SC-FC) coupling at three hierarchical levels (regional, intra-network, and inter-network) and assessed their associations with SWM performance. Finally, this study calculated the lateralization index (LI) of SC-FC coupling and evaluated its ability to discriminate ASD from normal sleep states. Compared with the baseline state, ASD induced significant reorganization of SC-FC coupling, exhibiting pronounced regional specificity and hierarchical differences. In particular, both regional and inter-network SC-FC coupling of the left limbic network showed a trend-level negative correlation with omission rate after ASD. In addition, the LI of SC-FC coupling in the subcortical network exhibited a moderate level of discriminative performance in distinguishing between the two states. Multilevel reorganization of SC-FC coupling induced by ASD provides new evidence for the neural mechanisms underlying SWM impairment.

The current study investigated the causal role of the right IFG in motivational regulation and whether individual differences in impulsivity interact with the IFG to predict motivational regulation. The current study (N = 33) employed low-frequency repetitive transcranial magnetic stimulation to transiently inhibit the functioning of the right or left IFG before a mobile approach-avoidance task. Results revealed that inhibition of the right, but not the left, IFG causes greater approach-motivated behavior in individuals high in impulsivity. These results suggest that the right IFG acts as an inhibitory mechanism that plays a causal role in approach motivation when a \"motivational amplifier\" is present, such as greater trait impulsivity. This study also suggests that the right IFG is especially important for regulating motivation in individuals with deficits in inhibitory control.

Neuroscientific evidence points towards the critical role of several regions in the right prefrontal cortex in the coordination and execution of this response inhibition-specifically the right inferior frontal gyrus (rIFG) and the right dorsolateral prefrontal cortex (rDLPFC). The present study investigated the effects of different transcranial magnetic stimulation (TMS) protocols on stop-signal task (SST) performance. We hypothesized that TMS over one or both of these areas would be detrimental to performance. However, contrary to our hypothesis, TMS significantly facilitated performance regardless of the stimulation condition. We applied both frequentist and Bayesian methods to assess the robustness of these effects, revealing consistent reductions in stop-signal reaction time (SSRT) across active conditions. Our results add to the growing body of results that suggest TMS effects may not be as straight-forward as usually assumed and that so-called \"inhibitory protocols\" can facilitate performance. This result could be explained by a shift in the signal-to-noise ratio depending on the pre-activation of the area. Put differently, TMS may have primed task-related activity in the target areas to a level that was optimal for task performance. Alternatively, the observed effect may reflect an (over)compensation by other parts of the network or disruption of competing resources.

This scoping review, following PRISMA-ScR guidelines, synthesizes findings from 45 fMRI, EEG, fNIRS, and autonomic nervous system (ANS) studies published between 1975 and 2024, exploring the neural basis of costly, other-oriented altruism. Our review covers experimental paradigms utilizing fMRI, EEG, and autonomic measures to interrogate neural and physiological responses associated with altruistic decision making and behavior. Importantly, inclusion was not limited to online, state-dependent, or event-related measurements; studies employing various acquisition timings were encompassed, as long as they examined neural or physiological correlates of altruistic motivation. fMRI studies consistently reveal engagement of a complex neural network, including medial and dorsolateral prefrontal cortex, temporoparietal junction, insula, and anterior cingulate cortex, integrating social cognition, value-based decision making, and emotional processing inherent in altruistic acts. EEG research highlights increased left frontal activity, indicative of approach-oriented motivation, and frontal midline theta, reflecting cognitive control during altruistic choices. ANS findings exhibit variability but tentatively suggest parasympathetic dominance in altruistic context. A key contribution is a multi-stage information-processing model of altruistic motivation, integrating these modalities from socio-affective appraisal through value computation, motivational orientation, and cognitive control to behavioral implementation. Findings elucidate the interplay of cognitive and emotional processes driving altruism, offering a nuanced conceptual framework.
