Summary: The study shows that activation of GPER1 in the DLS enhances cocaine-seeking behavior in female rats, but has no effect on male rats. This suggests that GPER1 may play a stronger role in regulating drug-seeking behaviors in females.

Summary: The preference shift towards cocaine in animals is not solely due to the direct suppression of sweet reward responding by cocaine pharmacological effects, as tolerance to this behavioral suppression did not prevent the preference shift towards cocaine. Other mechanisms must be involved to explain the influence of cocaine intoxication on choice outcomes.

Summary: This study compared the effects of unconscious cognitive reappraisal and expression suppression on emotional responses, based on neurophysiological data from 28 college students. The results showed that both strategies effectively reduced emotional arousal, but had different effects on neural activity. Expression suppression showed earlier and more widespread modulation of brain activity compared to cognitive reappraisal.

Summary: This study investigated the emotion-buffering effect of money priming on negative emotions under supraliminal and subliminal conditions using ERP experiment and DDM. Results showed that the buffering effect occurs automatically and unconsciously during early perceptual phase, and subliminal money priming is more effective in buffering negative emotions compared to supraliminal priming.

Summary: This study investigated the effects of reward and depth of processing on recognition during encoding and the underlying neural mechanisms. The results showed that reward improved item recognition accuracy, and the effect of reward was modulated by the depth of processing, with different processing tasks showing different levels of reward effect.

Summary: The ideas of face consciousness, group conformity, extended family concept, and crisis consciousness in Confucian culture have influenced housing consumption decisions among the Chinese public, leading to a preference for owning a house rather than renting one. There are differences in housing consumption stereotypes between high and low Confucian culture influence groups, and factors such as perceived usefulness, trust in the rental market, and policy perception play important roles in guiding public housing consumption stereotypes.

Summary: This study investigated attentional bias towards game-related cues in Internet gaming disorder (IGD) using LPP as a neurophysiological marker and explored the relationship between LPP and decision-making ability. The findings revealed that individuals with IGD exhibit higher LPP amplitudes when exposed to game-related cues, indicating deficits in decision-making ability.

Summary: Vulnerability to addiction is associated with the risk of developing an addiction during an individual's lifetime. This study used PET and SPM techniques to investigate changes in brain glucose metabolism in response to chronic morphine self-administration in two rat strains with different vulnerability to drug abuse. The results showed significant differences in brain metabolic patterns between the two strains, suggesting variations in the efficiency of neural substrates in translating the effects of the drug.

Summary: A hallmark of cocaine use disorder is dysfunction of dopamine signaling, particularly impaired D2 receptor signaling. Previous studies have mainly focused on males and found decreased D2 receptor binding in individuals with substance use disorder. However, this may not apply to females. This study aimed to assess sex differences in the role of D2 receptors in motivating cocaine use. Results showed that males, but not females, became less sensitive to D2 receptor antagonism with the development of an addiction-like phenotype.

Summary: This study examines the effects of using cap compared to facial electrodes to measure eye movements for ocular correction in event-related potential (ERP) research. Findings revealed comparable data quality but some differences in overall ERP magnitude, suggesting cap electrodes may be used if needed. A consistent approach to ocular correction within a study is recommended.

Summary: The study found that neural indicators such as the P300 were associated with long-delay verbal memory recall and diagnostic rating. Additionally, subjective memory complaints (SMCs) were found to be associated with higher perceived stress, anxiety, and depression symptoms, but were not a reliable indicator of early memory impairment.

Summary: Postnatal depression and anxiety disorders are a significant burden on maternal mental health. However, there is limited research on neural biomarkers of risk for postnatal increases in depression and anxiety. This study found that reduced antenatal P300 amplitude and enhanced LPP to positive infant images were associated with postnatal depressive and anxiety symptoms, respectively. These findings suggest that measuring ERPs during pregnancy may serve as a screening tool for perinatal depression and anxiety.

Summary: This study examined the electrocortical measures of error monitoring in early adolescents with and without OCD, using a data-driven, cluster-based approach. The results showed that participants with OCD exhibited increased error-related negativity and error-related theta, as well as reduced error-related beta power compared to those without OCD. The findings suggest that pediatric OCD may be characterized by enhanced error monitoring and post-error inhibition.

Summary: Complex systems theory is widely used to understand and explain interpersonal coordination and other interactional phenomena. In this paper, Butler extends this approach to analyze coordination in human interactions. However, we argue that the focus on physical aspects in complex systems theory overlooks the meaningful dimension present in human movements, reducing them to mechanical motions instead of expressive actions.

Summary: Non-pharmacological behavioral addictions, such as pathological gambling, videogaming, social networking, or internet use, are becoming major public health concerns. It is not yet clear how behavioral addictions could share many major neurobiological and behavioral characteristics with substance use disorders, despite the absence of direct pharmacological influences.

Summary: This study examined neurophysiological differences in adolescents with and without a history of preschool-onset depression (PO-MDD) using electroencephalography (EEG). The results showed that adolescents with a history of PO-MDD had smaller doors-P300 amplitude during cognitive exploration, while there were no group differences in reward feedback. Furthermore, smaller doors-P300 amplitude was associated with lower baseline income-to-needs ratio, older age, and female gender.

Summary: This study examined the impact of COVID-related worries on changes in anxiety symptoms among community dwelling older adults. It was found that COVID-related worries were associated with increased anxiety symptoms, but pre-COVID psychological resilience was associated with a decrease in anxiety symptoms. Furthermore, psychological resilience moderated the association, with greater increases in anxiety symptoms observed among individuals with low pre-COVID psychological resilience.

Summary: This study found that individuals in early abstinence from cocaine showed the most impairments in inhibitory control, while those in longer-term abstinence showed weaker impairments compared to healthy controls. Using functional magnetic resonance imaging (fMRI) data, the study also discovered decreased efficiency in fronto-temporal and subcortical networks and increased efficiency in visual networks among individuals with recent cocaine use. Importantly, these deviations in resting-state brain function were associated with both abstinence duration and inhibitory control deficits.
