Summary: The present study found that pictures of oneself elicited a larger late positive potential (LPP) compared to pictures of strangers and objects. The LPP was related to self-reported appearance anxiety and symptoms of BDD. These findings suggest that the LPP may serve as a neural marker of appearance concerns.

Summary: The study provides evidence that neural correlates of affective stimulus evaluation can be assessed at the individual case level, with different emotional stimulus classes affecting individuals differently. Evaluating emotional modulation of the EPN and LPP across multiple behavior systems strengthens case-by-case approach and differentiates effects specific to emotion categories within individuals.

Summary: The study investigated the impact of task demands on processing happy, sad, and fearful expressions behaviorally and electrophysiologically. The results showed that emotional content does not necessarily require attention in the early stages of face processing, with voluntary attention fully modulating the response to emotional content in the final stage of processing.

Summary: The study found that in depression, there is a reduction in delta power to pleasant pictures, while the control group showed an increase. Additionally, combining LPP and delta power can better explain changes in depression status, suggesting that these two electrocortical correlates might be related to unique physiological processes associated with depression.

Summary: Emotion counter-regulation is the core cognitive mechanism of automatic emotion regulation. It induces an unintentional shift of attention and prompts approach or inhibition to stimuli of opposite or same valence. The relationship between emotion counter-regulation and working memory updating with emotional stimuli remains unclear.

Summary: Evidence suggests that explicit reappraisal has limited regulatory effects on high-intensity emotions due to cognitive resource depletion caused by the emotional stimulus. Implicit reappraisal, on the other hand, is a resource-saving strategy that can effectively regulate high-intensity negative experiences. This study found that both explicit and implicit reappraisal can down-regulate negative experiences, but only implicit reappraisal had significant regulatory effects on high-intensity emotions.

Summary: Individuals with major depressive disorder (MDD) exhibit reduced reward positivity (RewP) and blunted neural responses to pleasant pictures, which may relate to anhedonia and decreased emotional engagement. The deficits in RewP and late positive potential (LPP) are independent neural markers of MDD and can help improve its classification.

Summary: The ability to accurately identify and interpret others' emotions is crucial during adolescence. This study examined the relationship between laboratory-based measures of socioemotional information processing and real-world affective dynamics in adolescents. The results demonstrate that prolonged engagement with happy or angry faces is related to resistance to changes in happiness or anger, highlighting the importance of laboratory measures in predicting and understanding adolescent affective states.

Summary: This study applied a machine learning approach to predict depression and PTSD symptoms among healthcare workers during the COVID-19 pandemic. It found that the level of stress due to social isolation and professional recognition were the variables that contributed the most to the predictive function. Interestingly, professional recognition had a negative predictive value, indicating an inverse relationship with PTSD and depression symptoms.

Summary: This study examined whether emotional information presented in a previous experiment could influence participants' emotional interpretation of neutral faces in a subsequent experiment. The results showed that in a negative context, participants were more likely to rate neutral faces as negative. This suggests that previous incidental emotional information can subtly modulate our emotional judgments.

Summary: The COVID-19 pandemic has exposed healthcare workers to traumatic situations that may lead to the development of posttraumatic stress disorder (PTSD). This study found that an important factor for PTSD is the peritraumatic tonic immobility (TI) reaction. Healthcare workers who reported high TI scores had a significantly higher probability of having a PTSD diagnosis. TI should be screened and psychoeducation about its biological nature should be introduced.

Summary: The study aimed to create a catalog of cytological pictures and assess the valence and arousal levels of these pictures in individuals with different occupations. The results showed that students rated the cytological pictures lower in valence and arousal compared to cytopathologists. However, the expertise in cytology did not affect the valence and arousal ratings for general pictures. Cytopathologists rated cytological pictures with lesions as lower in valence and higher in arousal compared to pictures without lesions.

Summary: This study investigated the factors associated with probable depression and posttraumatic stress disorder (PTSD) related to traumatic COVID-19 experiences and their impact on different categories of healthcare workers. A cross-sectional study recruited 1843 healthcare workers (nurses, nurse technicians, physicians, physical therapists, and other healthcare workers) through convenience sampling. A survey was conducted to gather information on sociodemographic, occupational, and mental health status. Statistical analysis included descriptive statistics and multivariable logistic regression. Being a nurse technician was associated with higher odds of probable PTSD, while no relationship was found between healthcare worker categories and the odds of probable depression. Female gender and inadequate personal protective equipment (PPE) were associated with higher odds of probable PTSD and depression.

Summary: Worldwide, discrimination against mothers based on stereotypes and misconceptions surrounding motherhood remains a major factor for women's reduced participation in the job market. In academia, mothers, especially women scientists, face negative bias that negatively affects their commitment and dedication. A survey conducted among Brazilian scientists revealed that mothers self-reported a higher prevalence of negative bias in the workplace compared to fathers, with the perception influenced by gender and career status, but not race, scientific field or number of children.

Summary: This study used resting-state functional magnetic resonance imaging to explore the relationship between individual's spontaneous neural activity and social interaction anxiety in a nonclinical population. The results showed that social interaction anxiety was correlated with the fractional amplitude of low-frequency fluctuations in several brain regions, and that emotional intelligence partially mediated this relationship. This study provides evidence for the neural basis of social interaction anxiety in the normal population and highlights the role of emotional intelligence in this anxiety.

Summary: This study provides morphometric data on the development of the human medullary arcuate nucleus (AN) by examining the brains of preterm and perinatal infants. The results show that AN morphology demonstrates asymmetry and individual variability during the fetal period. The volume and neuronal number of AN increase exponentially with age, while neuronal density decreases exponentially. The AN may undergo neuron death and neuroblasts production after mid-gestation.

Summary: This study investigated the effects of alamandine on allodynia in a rat model and found the presence of MrgD receptors in the vlPAG and RVM regions. Microinjection of alamandine resulted in a significant increase in paw withdrawal threshold and could be blocked by an MrgD receptor antagonist. Upregulation of MrgD receptor expression following allodynia induction suggests a potential compensatory mechanism in response to pain.

Summary: The present study aimed to investigate the separate and combined effects of anodal transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) and left dorsolateral prefrontal cortex (F3) regions on pain relief in patients with type-2 diabetes suffering from neuropathic pain (NP). The results showed that tDCS had the potential to induce pain relief in patients with type-2 diabetes suffering from NP. The mean perceived pain intensity in the posttest was lower in the M1 stimulation group than in the F3 stimulation group. However, more trials with larger sample sizes are necessary to define clinically relevant effects.

Summary: This study found a general impairment in humor comprehension in individuals with schizophrenia, with mental jokes being more difficult for both patients and controls. Humor comprehension was closely associated with the patients' overall pragmatic and linguistic profile, while the association with Theory of Mind (ToM) was minimal. Another notable finding was the increased appreciation of humor in individuals with schizophrenia, who rated jokes as funnier than controls did, regardless of whether they were correctly or incorrectly completed. The funniness ratings were not predicted by any measure, suggesting a dimension of humor untied to cognition or psychopathology.
