Summary: The study found that the impact of face masks on social interactions is not always negative, and masked faces may even be more attractive in certain traits. While face masks may affect the recognition of emotional expressions, they do not significantly impact judgments on other characteristics.

Summary: Current AI systems for determining emotions rely on facial features, but low-light images and masks hinder accuracy. This study proposes a method that enhances low-light images and uses upper facial features with a convolutional neural network for emotion recognition. The approach utilizes the AffectNet dataset, achieving 69.3% accuracy.

Summary: This study proposes using face morphing as a novel way of data augmentation to synthesize faces that express different degrees of a designated emotion, in order to improve the recognition of emotional intensity in facial emotional recognition systems. The approach has been successfully validated on both humans and machines.

Summary: The study found that illusions faces and human faces share common mechanisms in facial expression processing, suggesting that expression processing is not strictly bound to human facial features. The results also support the hypothesis of temporal continuity in facial expressions.

Summary: Unilateral right temporal lobe resections can impair facial identity recognition and reduce BOLD response to faces, while also affecting emotion recognition to a lesser extent. The right anteromedial temporal lobe plays a specific role in processing faces and facial expressions.

Summary: Nonverbal emotion recognition accuracy (ERA) is essential for successful communication, and two different training programs focusing on multimodal expressions and micro expressions respectively were evaluated. Results showed that the training program focusing on multimodal expressions was more effective in improving overall ERA, while the one focusing on micro expressions was more effective in improving micro expression ERA specifically. Transfer effects of the training programs were not observed, and participants with lower baseline ERA showed more improvements.

Summary: With the COVID-19 pandemic and the widespread use of face masks, recognizing emotions from facial expressions has become challenging. This study investigated how wearing masks affects the perception of emotions and the role of individual traits in emotion processing. The findings suggest that face masks increase uncertainty in recognizing emotions and decrease the perceived intensity of subtle expressions.

Summary: This study investigated humans' ability to recognize facial expressions represented by a small set of landmarks and differences in conscious observational behaviors. The results show that humans can recognize positive expressions with high accuracy, but recognition of negative expressions is not as high. Personality traits and observational behaviors significantly influence the recognition of facial expressions.

Summary: The systematic literature review presented the state-of-the-art on emotion expression recognition from facial images, classifying the methods into classical and neural networks approaches and finding a marginally better recognition precision for classical approaches. Additionally, it verified the most popular datasets for facial expression and emotion recognition, demonstrating a real demand for reliable data-sources.

Summary: Facial microexpressions are brief, subtle, and involuntary movements of facial muscles reflecting genuine emotions. A study developed fEMG and EEG-based methods for detection and recognition of emotions reflected in microexpressions, showing potential usability in practical scenarios. EEG was found to be more useful than fEMG for classifying discrete emotions, with the best F1 scores being 0.962 for EEG and 0.797 for fEMG.

Summary: The current longitudinal study examined maternal facial emotion recognition and infant affect-based attention using eye-tracking at different ages. The results showed consistent maternal responses to angry facial expressions, indicating a trait-like response to social threat among mothers. However, neither maternal responses to happy or fearful facial expressions nor infants' responses to all three facial emotions showed such consistency, suggesting the changeable nature of facial emotion processing, especially in infants. The study also found dynamic changes in infants' attention to negative emotions and limited evidence for developmental continuity in processing negative emotions and the bidirectional interplay of infant affect-biased attention and maternal facial emotion recognition.

Summary: This study investigated the characteristics of real and fake facial expressions of representative emotions within a two-dimensional emotion model. Significant differences in feature variables were found between real and fake expressions, with variations based on emotions and facial regions. These findings provide criteria for identifying the authenticity of facial expressions, which can be applied to future research and the design of emotion recognition systems.

Summary: This study aimed to investigate if European neurotrauma centers can be clustered based on their treatment preference in different domains of traumatic brain injury care in the intensive care unit (ICU). Provider profiles from 66 centers in 20 different countries in Europe and Israel were analyzed, revealing correlations within and between treatment domains, but hospitals could not be grouped based on their treatment preference.

Summary: The incidence of Traumatic Brain Injury (TBI) is increasingly common in older adults, and it poses a growing public health problem. However, there is a lack of research on TBI in older adults. This study provides an overview of healthcare utilization and outcomes after TBI in older adults, and identifies the determinants of these outcomes. The findings indicate that the rate of impairment and disability following TBI is substantial in older adults, and poorer outcomes are associated with worse pre-injury health. However, a considerable number of patients are able to return to their pre-injury functioning.

Summary: Our study found that a higher CAIDE score is associated with widespread cortical thinning and a larger hippocampal fissure, while the APOE4 genotype is associated with reduced molecular layer clarity. These results suggest that cardiovascular rather than inherited risk factors are associated with macrostructural brain alterations in midlife.

Summary: Perturbations in a large-scale whole-brain model reveal that anesthesia and injury can have similar effects on brain dynamics. A computational model incorporating PET and diffusion MRI data shows that spatially-specific local inhibition and connectome perturbation play key roles in reproducing the brain activity observed during anesthesia and disorders of consciousness. These findings suggest common neurobiological mechanisms underlying these conditions.

Summary: This study aimed to develop ordinal prediction models for traumatic brain injury patients' functional recovery at six months and analyzed the impact of expanding predictor sets and modeling strategies on model performance. The results showed that expanding predictor sets significantly improved prediction performance, but the effect decreased at higher functional recovery levels. These findings provide insights for identifying informative predictors and developing ordinal dynamic prediction models.

Summary: A novel approach combining modern theories of consciousness, phenomenology, and dynamical systems theory is used to investigate the relationship between consciousness and dynamic connectivity. The study reveals that consciousness is associated with faster, more unpredictable, yet more constant transitions in connectivity. It also suggests a richer space of possible states, as temporally-specific connectivity states are less easily describable by distant network patterns.

Summary: Recent studies have found evidence of increased microglial activation, indicating inflammation, in cerebral small vessel disease. However, it is unclear whether these areas of neuroinflammation progress to tissue damage. This study showed that white matter destined to become white matter hyperintensities already exhibited signs of altered inflammation at baseline.

Summary: The article presents a protocol for measuring human brain activity using ultra-high field (UHF) neuroimaging, with detailed steps on data preprocessing and vasculature-related confounder correction. By combining tools from SPM, FreeSurfer, ITK-SNAP, and BrainVoyager, spatial accuracy of the fMRI signal can be improved.
