Summary: The study explores the cortical activities and brain oscillations during wind-up, a phenomenon in which pain sensations are facilitated by repeated application of constant intensity noxious stimuli. The results show that repetitive stimulation at a constant intensity can enhance evoked cortical activity and induce specific oscillations, suggesting a pain mechanism associated with wind-up.

Summary: For diseases that affect brain function, post-onset rehabilitation is crucial. To aid effective rehabilitation, a neurofeedback system that monitors brain activity in real time is necessary. This requires a quick analysis method that encourages neural oscillations and allows for changes in oscillation patterns during rehabilitation.

Summary: Using MEG technology, this study found that children with autism spectrum disorder (ASD) exhibited bilateral reduction in alpha-band event-related desynchronization (ERD) in the auditory cortex, but not in the visual cortex. Furthermore, alterations in the auditory cortex were associated with a higher presence of autistic traits measured in behavioral assessment.

Summary: The study identified higher anticipation in ALS patients compared to healthy controls during the SART task. Decreased beta-band event-related desynchronization was found in ALS patients, not related to task performance. Patients with higher ALS-specific scores demonstrated stronger beta-band event-related synchronization upon successful withholding.

Summary: Magnetoencephalography (MEG) is effective in studying the oscillatory rhythms and control of human motor cortex. This study introduces a new approach that combines an MEG compatible driving simulator with differential beamformer methods to investigate the neural correlates of realistic, complex motor activity. The results demonstrate that the driving task can elicit significant modulation in brain activity related to motor responses, movement-related gamma synchrony, and frontal cognitive control responses.

Summary: This study aimed to identify the dominant factor for inducing event-related desynchronization (ERD). The results showed that ERD was significantly attenuated in the absence of force feedback, while it was maintained in the presence of force feedback. Additionally, the extent of ERD was found to reflect neural activity involved in the motor planning process for changing virtual equilibrium point.

Summary: The CC genotype of the clusterin (CLU) rs11136000 gene is a probable risk factor for Alzheimer's disease (AD), similar to the well-established relationship of the apolipoprotein E (APOE) gene with AD. This study aimed to determine if the electrophysiological patterns of brain activation during the letter fluency task (LFT) depend on CLU genotypes. The results show that the CLU genotype is associated with neuronal hyperactivation in the frontal cortex during cognitive task performances in nondemented individuals, suggesting systematic vulnerability of LFT related cognitive networks in people carrying unfavorable CLU alleles.

Summary: Symptoms of OCD are associated with impairment in cognitive control, attention, and action inhibition. A study was conducted to compare OCD patients with healthy controls in terms of brain oscillatory activity during a Go/NoGo task. The results showed that OCD patients exhibited changes in alpha/beta power over different brain regions, indicating dysfunction in action preparation, inhibition, and visual stimulus evaluation. These findings suggest significant involvement of specific brain circuits and overfocused attention in the pathology of OCD.

Summary: It has been observed that both actual and imagined tactile stimuli can result in event-related desynchronization (ERD) in the electroencephalogram (EEG) recorded over the corresponding motor areas. This study compared the effects of real and imagined vibrotactile stimulation of the right hand using EEG recordings in healthy individuals. Both real and imagined sensations produced contralateral ERD patterns, with the most significant effects observed in the m-band and C3 region. The findings suggest the potential use of EEG patterns induced by tactile imagery as control signals in brain-computer interfaces (BCIs) for sensorimotor rehabilitation after stroke and neural trauma, particularly when combined with motor imagery (MI).

Summary: The study found that participants with high power used fewer cognitive resources during task completion compared to low-power participants, but task performance did not differ significantly between groups. High-power individuals demonstrated greater cognitive efficiency rather than investing more resources. Performing tasks efficiently can help individuals with power deal with their work and responsibilities.

Summary: This study investigated the impact of motor imagery-based training (MI) on corticospinal excitability, finding that engaging in MI in 4-minute blocks may be more effective in generating and maintaining corticospinal excitability compared to 2-minute and 6-minute blocks. The findings provide physiological evidence to optimize the structure of MI training sessions for better effectiveness.

Summary: The study found that brain alterations are already present in patients with first episode of psychosis, and worsen over time in those with worsening clinical outcomes or higher baseline BMI. This suggests that obesity may be a modifiable risk factor linked to psychiatric outcomes through effects on brain structure.

Summary: This study shows that motor imagery involves the simulation of a movement, and its accuracy varies. The characteristics of the movement have a significant impact on the accuracy of the imagery, while the vividness of the imagery has a small effect. The complexity of the imagined movement does not affect the movement time, further supporting the idea that imagined movements are simulated rather than abstractly represented.

Summary: This survey compares the burden of illness among individuals with a history of Lyme disease (HLD) who have contracted COVID-19 or received the COVID-19 vaccine. The results show that the overall burden of illness for individuals with HLD is not significantly different after contracting COVID-19 or receiving the vaccine. A new survey is needed to better understand why one in five individuals with HLD reported long COVID after contracting COVID-19. These findings can help clinicians and patients discuss the consequences of COVID-19 infection or vaccination.

Summary: Although motor learning can occur from action observation, observers' confidence in their ability may be falsely increased. Motor imagery is believed to be linked to an understanding of movement consequences and kinaesthetic information, providing better access to sensory information and reducing over-confidence.
