Perception of facial identity and emotional expressions is fundamental to social interactions. Recently, interest in age associated changes in the processing of faces has grown rapidly. Due to the lack of older faces stimuli, most previous age-comparative studies only used young faces stimuli, which might cause own-age advantage. None of the existing Eastern face stimuli databases contain face images of different age groups (e.g. older adult faces). In this study, a database that comprises images of 110 Chinese young and older adults displaying eight facial emotional expressions (Neutral, Happiness, Anger, Disgust, Surprise, Fear, Content, and Sadness) was constructed. To validate this database, each image was rated on the basis of perceived facial expressions, perceived emotional intensity, and perceived age by two different age groups. Results have shown an overall 79.08% correct identification rate in the validation. Access to the freely available database can be requested by emailing the corresponding authors.

Here, we will review the developmental literature on how infants and young children learn about emotions. We take a process-based perspective, highlighting how the protracted trajectory of emotional development unfolds concurrently with changes in children's cognitive abilities, and how variability based on context, culture, and experience shape this trajectory over time. We will also emphasize the role of input into this development, a factor that has often been ignored.

Early diagnosis of Parkinson's disease (PD) is crucial for timely treatment and disease management. Recent studies link PD to impaired facial muscle control, manifesting as "masked face" symptoms, offering a novel diagnostic approach through facial expression analysis. However, data privacy concerns and legal restrictions have resulted in significant "data silos", hindering data sharing and limiting the accuracy and generalizability of existing diagnostic models due to small, localized datasets.

Orofacial neuropathic pain, a debilitating condition associated with trigeminal nerve injury, is often characterized by allodynia. N-methyl-d-aspartate receptors (NMDARs), particularly the GluN1 subunit, play a central role in mediating this pain. The GluN1 subunit undergoes alternative splicing at exon 5, generating isoforms GluN1a (lacking the exon 5-encoded N1 cassette) and GluN1b (retaining the N1 cassette), which have distinct functional roles.

Previous studies have investigated whether event-related potential (ERP) responses to negative and positive facial expressions are modulated by perceptual and working memory loads of face-irrelevant tasks, but results have been mixed. These studies typically employed traditional analysis methods that focus on a limited number of electrodes and timepoints, which increases the risk of statistical errors. Moreover, no studies have investigated these issues for emotionally ambiguous facial expressions.

CHOPS (cognitive impairment, coarse facies, heart defects, obesity, pulmonary involvement, short stature, and skeletal dysplasia) syndrome is an extremely rare disorder with multiple congenital anomalies caused by missense variants in the ALF transcription elongation factor 4 gene (). This study aimed to identify causative variants in a Chinese family with CHOPS syndrome. A Chinese girl with short stature, obesity, and developmental delay underwent comprehensive clinical and genetic evaluations, including karyotyping analysis, multiple ligation-dependent probe amplification, detection of aberrant methylation, whole exome sequencing, Sanger sequencing, and copy number variation analysis, followed by analyses.
