Summary: This study aimed to investigate modifications of FFA activation during face encoding and maintenance in individuals with Developmental Prosopagnosia (DP) using Representational Similarity Analysis (RSA). The results showed that DP participants failed to generate robust and sustained neural representations in the FFA during face processing, leading to poorer task performance and longer reaction times. Such alterations in neural coding in the FFA may contribute to impaired working memory and long-term memory.

Summary: The functional role of the occipital face area (OFA) and the fusiform face area (FFA) in face recognition is still inconclusive. This study used multifocal transcranial direct current stimulation (tDCS) to further examine their roles. Results showed that FFA stimulation enhanced facial feature recognition, while OFA stimulation had no effect on either facial feature or whole face recognition.

Summary: In this study, resting-state functional magnetic resonance imaging (rsfMRI) was used to study functional connectivity (FC) in chronic occipital stroke patients with homonymous visual field defects before and after receiving repetitive transorbital alternating current stimulation (rtACS). The results showed no significant differences in whole-network FC between occipital stroke patients and healthy controls, and rtACS treatment did not affect FC in this setting.

Summary: This study investigates a new case of acquired prosopagnosia and finds that the structurally intact FFA retains face selective response despite lesions in the face perception network. At the behavioral level, impaired configural processing for facial identity was observed, but not for other stimulus categories and facial expression recognition. These findings are important for understanding the behavioral and brain basis of face perception.

Summary: Previous studies have focused on the impairment of holistic and configural processing mechanisms in developmental prosopagnosia (DP). This study used a data-driven approach and found systematic patterns of variability in DP that reflect different underpinning perceptual deficits. The findings indicate two separable pathways to face recognition impairment.

Summary: By studying 1053 participants, researchers found five main findings regarding fusiform face-selective regions, including two spatially contiguous regions that are functionally and architecturally distinct, with one being more face-selective; the similarity of these regions is higher in monozygotic twins rather than in different brain regions.

Summary: Previous cross-sectional studies found differences in the structure and function of the fusiform face area (FFA) related to face processing between users and non-users of combined oral contraceptives (COCs). In this study, female participants were categorized as never-users, current first-time users of androgenic or anti-androgenic COCs, or previous users of androgenic or anti-androgenic COCs. Results showed that the association between COC-use and face processing is influenced by androgenicity and does not persist after COC use. The left FFA's connectivity to the left supramarginal gyrus (SMG) is a key region in cognitive empathy and is affected by COC use.

Summary: The study found that super recognizers and developmental prosopagnosics rely more heavily on critical facial features than non-critical features for face identification, similar to normal individuals. The results emphasize the fundamental role of this subset of features for face recognition.

Summary: Individuals with developmental prosopagnosia (DPs) experience severe deficits in recognizing faces, particularly in identity discrimination. However, their deficits in expression discrimination are subtle. Our study compared identity and expression processing in DPs and found dissociations between these two processes. DPs showed impaired performance in identity discrimination but relatively normal performance in expression discrimination.

Summary: Understanding how the human brain recognizes faces is a primary goal in cognitive neuroscience. Recording electrophysiological activity with implanted electrodes in the brains of epileptic patients has been a key approach, but there are challenges that need to be overcome. Large-scale studies combining intracerebral activity recording and visual stimulation have provided insights into the neural basis of human face recognition.

Summary: This study investigated whether there are qualitative differences in face processing between DP patients with high and low AQ scores. The results showed that both groups had deficits in face memory and perception, while the high AQ group also demonstrated deficient face emotion recognition.

Summary: The brain's functional architecture and organization undergo continuous development and modification throughout adolescence. This study systematically evaluated over 47,000 youth and adult brains to examine time-resolved functional connectivity patterns and found distinct differences between the two life stages, indicating an overall inverted U-shaped trajectory in the strengthening and modularization of functional coupling. These findings suggest greater synchrony and integration of the brain's functional connections beyond adolescence, with a gradual decline during healthy aging.

Summary: This study found that humans and DCNNs use similar critical information for face gender classification tasks, mainly concentrated in low spatial frequencies. Task experience in processing faces at the subordinate level seems necessary for such representational similarity between humans and DCNNs.

Summary: The study identified consistent associations between neuroticism and gray matter structures in the brain, particularly with the bilateral dorsal anterior cingulate cortex and adjacent medial prefrontal cortex. These associations were not confounded by age and gender, suggesting potential implications for intervention targeting these brain regions in high-neuroticism individuals at risk of mental disorders.

Summary: The increasing popularity of AI applications poses the risk of amplifying social bias, such as classifying non-white faces as animals. Recent research attributes this bias to the training data utilized, with imbalance of face images leading to performance differences in identification processes.

Summary: Our study found that individuals with better face recognition ability and more extraverted personality tend to have larger social network size. Additionally, we observed positive associations between SNS and fALFF in the ventromedial prefrontal cortex (vmPFC), right superior temporal sulcus, and precuneus. The fALFF in the vmPFC was significantly correlated with face recognition ability.

Summary: This study developed and validated the Diagnostic Chinese Reading Comprehension Assessment (DCRCA) for primary students under the Cognitive Diagnostic Assessment (CDA) framework. Reading attributes were synthesized to construct reading comprehension items for 2-6 graders, and the assessment was administered to a large population of students in China. Comparisons of five cognitive diagnostic models revealed that a six-attribute structure and the G-DINA model were best fitted for the reading comprehension assessment.
