Summary: The growth mindset refers to beliefs in the malleable nature of intelligence and plays a significant role in motivation and achievement. This study utilized voxel-based morphometry to investigate the relationship between growth mindset and gray matter volume (GMV) in healthy adults. Whole-brain correlation analyses revealed a positive association between growth mindset scores and regional GMV in the medial orbitofrontal cortex (mOFC) after controlling for age, sex, and total intracranial volume. This finding remained robust even after adjusting for intelligence quotient, highlighting the relevance of the mOFC in reward processing, supporting the social-cognitive theory of motivation in the context of growth mindset.

Summary: To succeed, taking risks wisely is crucial, which depends on individual ability to exploit risk. A study using voxel-based morphometry (VBM) revealed that the ability to exploit risk was correlated with gray matter volumes in the orbitofrontal cortex and dorsolateral prefrontal cortex. The findings suggest that precise valuation, adaptive learning, and self-control play a role in the ability to exploit risk.

Summary: Emotion recognition declines with age, but it is unclear whether this is due to structural brain changes. A study using voxel-based morphometry analysis found no correlation between gray matter volume changes and age-related decline in emotion recognition. However, exploratory analysis suggested that gray matter volume may be related to overall emotion recognition, although the effect size is small.

Summary: Major depressive disorder, anxiety disorders, and chronic pain are closely related disorders with both shared and distinct changes in brain networks. The common changes suggest neural correlates for comorbidity, while the disorder-specific changes may underlie distinct phenotypes and mechanisms.

Summary: This study examines the characteristics of gray matter in post-traumatic anosmia (PTA) patients using surfaced-based morphometry (SBM) and voxel-based morphometry (VBM). The results show that PTA patients have reduced olfactory bulb (OB) volume and olfactory sulcus (OS) depth, and there are overlapping changes in the VBM and SBM findings in specific brain regions. Furthermore, correlations are found between the orbitofrontal cortex and odor threshold score, as well as the middle frontal gyrus and smell loss duration.

Summary: The present longitudinal study investigated the impact of L2 learning on the grey matter structure of Chinese college freshmen majoring in English. Results showed that after one year of L2 learning, grey matter volume decreased in the left anterior cingulate cortex and right inferior frontal gyrus, which correlated with changes in participants' language control ability. Age of acquisition of L2 and L2 proficiency were significant predictors of volumetric change in specific brain regions.

Summary: This article aimed to investigate the common and certain neural alterations in the structure and function of the brain in patients with ADHD through a comprehensive analysis of multiple neuroimaging studies. The study found abnormal changes in the structure and function of the brain in ADHD patients, which may be associated with the left superior frontal gyrus and the corpus callosum, serving as imaging metrics for ADHD patients in the future.

Summary: This study found smaller overall gray matter volume in patients with Parkinson's disease, particularly in the right superior temporal gyrus and left frontotemporal region. This structural abnormality may be correlated with patients' age and severity of movement disorder, and enhanced brain activity was also observed.

Summary: In this study, brain structural alterations and relevant functional changes in patients with postpartum depression (PPD) were investigated. The findings revealed increased gray matter volume in the left dorsolateral prefrontal cortex, right precentral gyrus, and orbitofrontal cortex of PPD patients compared to healthy postnatal women. The functional connectivity between these regions also showed enhancement. Additionally, the increased gray matter volume in the left dorsolateral prefrontal cortex and the functional connectivity between the right precentral gyrus and right median cingulate gyrus were positively correlated with the severity of depression symptoms.

Summary: This study found that sleep deprivation impairs attention, arithmetic ability, episodic memory, and working memory, while different times of day can affect performance on attention and arithmetic tests. The results suggest that smartphone-based cognitive tests can be effectively used to assess cognitive impairments following sleep deprivation and fluctuations in cognitive performance related to time of day.

Summary: This study investigated the vulnerability factors to inflammation-induced sickness and anxiety responses in individuals, and found that the gray matter volume of the anterior insula plays a central role in the development of symptoms. The results suggest that anterior insula morphology may be a risk factor in inflammation-related psychopathologies.

Summary: Despite poor treatment results, a family-oriented approach and securing residency have been found essential to recovery from resignation syndrome (RS), and separation from parents and abstaining from involving the asylum process may be crucial in treatment. The study showed that patients who were separated from their parents and did not invoke residency permit had a higher recovery rate.

Summary: The study found that higher polygenic risk scores for both bipolar disorder and schizophrenia were associated with a thinner ventromedial prefrontal cortex (vmPFC), a brain region involved in self-referential processes and emotional regulation. This association was observed in both patients and drug-naive controls. Additionally, polygenic risk for bipolar disorder was correlated with the functional hub strength of the vmPFC within the default mode network.

Summary: The study found that psychedelic drug use is weakly associated with psychosis-like symptoms, largely explained by psychiatric comorbidities and use of other psychoactive substances. Additionally, psychedelics may have an effect on flexibility of evidence integration and aversive learning processes.

Summary: Psychosis is associated with distorted perceptions and deficient bottom-up learning. Patients with psychosis rely more on high-order priors to interpret perceptual input. This study found that delusion-prone individuals showed stronger instructed fear learning and weaker classical fear conditioning.

Summary: Fluid intelligence is considered beneficial for protecting against stress and ill-health. However, this experimental study showed that higher fluid intelligence did not provide resilience to the cognitive effects of sleep deprivation. In fact, those with higher fluid intelligence were more impacted by sleep deprivation, particularly in arithmetic ability, episodic memory, and spatial working memory. It highlights the need for a more nuanced understanding of the relationship between intelligence and cognitive advantages.

Summary: This study aimed to investigate if compulsive sexual behavior disorder (CSBD) is associated with structural brain differences in regions involved in reward processing. The findings showed that CSBD patients had lower cortical surface area in the right posterior cingulate cortex and a negative correlation between the area and CSBD symptom severity. These results contribute to a better understanding of the neurobiological mechanisms underlying CSBD.

Summary: The neurocomputational framework of predictive processing (PP) offers a promising explanation for delusions in psychotic disorders. According to PP, the brain makes inferences about the world by weighing prior beliefs against sensory data. Psychosis has been associated with reduced weighting of priors, but delusional beliefs are highly resistant to change, suggesting increased weighting of priors. We propose that this delusion paradox can be resolved within a hierarchical PP model.
