Summary: The study found that while interindividual differences in ERPs at Time 1 did not predict attentional breadth differences across individuals at Time 1, individual differences in changes to P1, N1, and P3 ERPs to hierarchical stimuli from Time 1 to Time 2 were associated with individual differences in changes in attentional breadth from Time 1 to Time 2.

Summary: This study investigated the temporal processes of attentional modulation under high perceptual load using a perceptual load paradigm, considering perceptual load, distractor-target compatibility, and eccentricity. The results showed that high perceptual load significantly reduced attentional distraction from peripheral distractors, and the event-related potential results revealed shorter P2 latencies for peripheral distractors compared to central distractors under high perceptual load. The P3 component reflected a suppressed compatibility effect with increasing load. These findings suggest that the P2 and P3 components capture different aspects of attentional processing modulated by load and that the response patterns of selective attention modulated by perceptual load are influenced by eccentricity. Our electrophysiological evidence confirms the behavioral findings and indicates the neural mechanisms of attentional modulation.

Summary: This study aimed to investigate the impaired impulsivity control in individuals with bipolar I disorder (BD) and whether similar difficulties are present in schizophrenia spectrum disorders (SZ). The results suggest that both BD and SZ patients have difficulties in discriminating emotional faces from neutral faces, which may contribute to difficulties in appropriate behavioral responding in social-affective contexts.

Summary: The study reveals the existence of human-like ERP components related to voluntary attention and reflexive attention in lower vertebrates, specifically in Emei music frogs. Results indicate that both voluntary attention and reflexive attention may be simultaneously engaged in auditory perception in this species, with different brain areas showing distinct responses to predicted and unpredicted acoustic stimuli.

Summary: Research suggests that individuals with high pain sensitivity are more likely to experience fear generalization related to pain, possibly due to their heightened sensitivity towards the threat of pain and allocation of more attention resources to pain-related threatening stimuli.

Summary: Numerous studies have shown that total sleep deprivation (TSD) impairs sustained attention. However, it is still unclear whether TSD affects the processing of visual selective attention. In this study, participants performed a visual search task before and after TSD, and the results revealed a decrease in accuracy and an increase in response time variability after TSD. Further analysis of event-related potentials (ERPs) indicated changes in brain activity after TSD. These findings provide new evidence and insights into the effects of sleep loss on visual attention.

Summary: Event-related potential studies have shown that selective attention to the valence of affective words can improve early emotional discrimination. Similar effects may occur when attending to specific emotions in facial expressions, leading to enhanced early processing of faces expressing the attended emotion. This study investigated the effects of selective attention on facial affect and found that it can enhance early emotional processing and also revealed a negativity bias in late controlled processing of facial emotions.

Summary: This meta-analysis examined the effects of transcranial direct current stimulation (tDCS) on P3 amplitude and latency. The results showed that anodal stimulation over the left dorsolateral prefrontal cortex and right inferior frontal gyrus increased parietal P3 amplitude during oddball and n-back tasks, suggesting the potential usefulness of parietal P3 ERP as a marker for tDCS-induced effects.

Summary: The study found that exogenous attention transiently modulates visual detail in the foveola, enhancing detail discrimination ability at the cued location without extending to nearby locations. On a longer timescale, an inverse effect was observed, with sharper acuity at unattended locations resembling inhibition of return at larger eccentricities.

Summary: This study successfully established a rat model based on the genetic-environmental interaction, which exhibited phenotype characteristics similar to human AD in terms of cognitive function, brain microstructure, and immunohistochemistry. The genetic factor (APP mutation) and the environmental factor (acrolein exposure) accounted for 39.74% and 33.3% of the AD-like phenotypes in the model, respectively.

Summary: This study examines the functional connectivity changes in individuals with sudden sensorineural hearing loss (SSNHL) at the integrity, network, and edge levels. The findings reveal reduced intranetwork connectivity strength and increased internetwork connectivity in SSNHL patients. These alterations are associated with the duration of SSNHL and Tinnitus Handicap Inventory scores. The study provides crucial insights into the neural mechanisms of SSNHL and the brain's network-level responses to sensory loss.

Summary: In the early stages of SAD, memory impairment is strongly correlated with cortical levels of soluble amyloid-beta peptide oligomers. A beta disrupts glutamatergic synaptic function and leads to cognitive deficits. This article describes the pathogenic mechanisms underlying cerebral amyloidosis, involving amyloid precursor protein synthesis, A beta residue clearance processes, and the role of specific molecules.

Summary: Depression has a higher incidence in women compared to men, and this study investigated the impact of sex on depressive behaviors and underlying mechanisms using a corticosterone-induced depression model in mice. The results showed sex-specific anxiety and depression behaviors in the model group, as well as differences in protein expression and neurotransmitter levels between male and female mice. These findings enhance our understanding of sex-specific differences in depression and support tailored interventions.

Summary: This study explores the effects of prolonged mask usage on the human brain by analyzing EEG and physiological parameters. The results show that the mean EEG spectral power in alpha, beta, and gamma sub-bands of individuals wearing masks is smaller than those without masks. The performances on cognitive tasks and oxygen saturation level differ between the two groups, while blood pressure, body temperature, and heart rate are similar. The analysis also reveals that the occipital and frontal lobes exhibit the greatest variability in channel measurements.

Summary: This study observed changes in brain infarction and blood vessels in rats during neonatal hypoxic ischemic encephalopathy (NHIE) modeling using Transcranial Doppler Ultrasonography (TCD). Longer duration of hypoxia was associated with more severe nerve damage. TCD can dynamically monitor cerebral infarction after NHIE modeling, which may serve as a useful auxiliary method for evaluating animal experimental models.
