Summary: The COMT gene polymorphism is associated with individual cognitive function in aging. Individuals carrying the Met allele showed better cognitive performance and lower diffusivity values in several brain regions. These findings suggest a protective effect of the COMT Met allele on cognitive decline in late life.

Summary: The study investigated the effect of different task complexity on EEG signals during motor learning. Results showed that complex training led to a significant decrease in Beta band power and increase in Gamma band power, particularly in frontal and central regions. Performance variations were mainly correlated with changes in beta and gamma power. Additionally, connectivity between frontal and central regions significantly increased in the complex training group.

Summary: The use of clinical psychoactive drugs can pose unpredictable threats to fetal development. Opicapone, a newly effective peripheral COMT inhibitor, is used for the treatment of Parkinson's disease and other dopamine-related disorders. However, the impact of opicapone on embryonic development is still unknown.

Summary: This study aimed to investigate the possible association between COMT and OPRM1 genotypes and pain perception in patients undergoing total hip replacement and total knee replacement. The results showed no significant genetic associations between variants of COMT and OPRM1 and pain thresholds/pain tolerance in the study group, and no relationship between specific genetic variants and subjective pain perception using the visual analog scale.

Summary: Transcranial magnetic stimulation (TMS) is an effective and well-tolerated non-invasive method for controlling refractory epilepsy, with potential to guide treatment based on changes in EEG biomarkers. This case demonstrates the efficacy of low-frequency repetitive TMS (rTMS) in reducing seizure frequency and the association between EEG biomarkers and seizure control.

Summary: This study investigates the temporal and frequency abnormalities in ADHD and its subtypes using high-density EEG. The results show differences in the salience network and frequency power between ADHD patients and healthy controls. Subtype differences primarily exist in the visual network, with ADHD-C patients showing a more activated visual network. Furthermore, the support vector machine model achieves high accuracy in classifying ADHD and its subtypes.

Summary: Cognitive workload has a significant impact on brain frequency spectral power, with theta showing the most notable sensitivity to CWL. Alpha and beta power are also influenced by CWL, but their association appears less straightforward. Further research is needed to explore the interaction between CWL and other factors affecting spectral power.

Summary: This study investigates the association between functional gene variants of the dopamine transporter and catechol-O-methyltransferase with ADHD-related impulsive behavior, executive deficits, and disease persistence. The findings suggest that these genetic variants may serve as predictors for the success of individual therapeutic sessions during cognitive training.

Summary: This study found significant differences in EEG spectral powers among non-OSA participants and those with different severities of OSA, particularly in the beta and sigma bands. After controlling for confounding factors, it was discovered that OSA patients had higher beta power and lower sigma power, with beta power decreasing as the severity of OSA increased.

Summary: This study compared the effectiveness of different BCG correction methods in preserving EEG spectral features, with results showing that ICA-based correction approaches were more beneficial for retaining EEG signal reactivity. Additionally, different correction methods had an impact on the results of EEG-informed fMRI analysis.

Summary: This study found that frequencies of EEG oscillations are associated with the onset, severity, and recovery of postoperative delirium. The relative power in specific frequency bands of the EEG is correlated with the severity and core features of delirium. These findings have implications for future mechanistic and interventional trials.

Summary: Previous spectral analysis studies on insomnia have shown inconsistent results. This study compared the difference of electroencephalogram (EEG) spectral power during sleep among participants without insomnia, insomniacs with no hypnotic use, hypnotic users with no insomnia complaints, and hypnotic users with insomnia complaints. The results showed that there were differences in the microstructures of sleep EEG between the two groups, particularly in the beta and sigma bands.

Summary: This study aimed to investigate the validity and reliability of the new wireless EEG device Mentalab Explore for resting-state EEG recordings. The results showed that the Mentalab Explore device was comparable to clinical-grade devices in terms of alpha peak frequency and alpha suppression, indicating that it is a reliable and valid EEG recording device for rsEEG spectral features.

Summary: The study used meta-analysis to demonstrate a significant association between COMT Val158Met polymorphism and antipsychotic response, which was consistent in both Caucasian and Asian patient populations. Genotyping of patients for predicting antipsychotic response may be relevant for future randomized clinical trials.

Summary: This study aimed to investigate the effects of high adiposity on executive functioning in young women and its relationship with dietary intake. The results showed deficits in executive function, category formation, and cognitive flexibility, as well as poor sustained and selective attention, and less verbal fluency in the high-adiposity group. Furthermore, there were correlations between certain nutrients and specific cognitive measures.
