Motor imagery-based Brain-Computer Interfaces (BCIs) restore control in persons with motor impairments, but up to 30% of users struggle, a phenomenon known as "BCI inefficiency". This study tackles a key limitation of current protocol: the ...
Non-specific increase in alpha power during a neurofeedback session targeting its downregulation [0.03%]
神经反馈训练降低alpha波功率的过程中其整体功率水平的非特异性增强现象

Functional MRI (fMRI) data are severely distorted by magnetic field (B0) inhomogeneities, which currently must be corrected using separately acquired field map data. However, changes in the head position of a participant across fMRI frames ...
Motor- and cognitive-dominant functional network adaptations supporting dual-task performance in older adults [0.03%]

Aging is associated with declines in both motor and cognitive functions, which are often examined using cognitive-motor dual-task paradigms. However, the functional brain network mechanisms supporting dual-task performance across these doma...
Does the brain's E:I balance really shape long-range temporal correlations? Lessons learned from 3T MRI [0.03%]
大脑的兴奋性-抑制平衡真的影响长程时间相关吗？从3T磁共振成像中得到的启示

Lydia Sochan
A 3T multimodal MR study of healthy adults (n = 18; 10 female; 21.3-53.4 years) was performed to investigate the relationship between functional magnetic resonance imaging (fMRI) long-range temporal correlations and excitatory/inhibitory ba...
Beta bursts spatiotemporal profiles and their links to hemodynamic responses during movement and rest [0.03%]
运动和休息期间的β频段爆发的时空分布及其与血流动力学信号的关系研究
