Spatial attention enables us to select regions of space and prioritize visual processing at the attended locations. Previous research has shown that spatial attention can be flexibly tuned to broader or narrower regions in space, and in som...
Childhood adversity predicts striatal functional connectivity gradient changes after acute stress [0.03%]

As a primary risk factor for psychiatric vulnerability, childhood adversity (CA) leads to several maladaptive behavioral and brain functional changes, including domains of emotion, motivation, and stress regulation. Previous studies on acut...
The temporal specificity of BOLD fMRI is systematically related to anatomical and vascular features of the human brain [0.03%]

The ability to detect fast responses with functional MRI depends on the speed of hemodynamic responses to neural activity, because hemodynamic responses act as a temporal low-pass filter which blurs rapid changes. However, the shape and tim...
Improved myelin water imaging using B 1 + correction and data-driven global feature extraction: Application on people with MS [0.03%]
基于B1+校正和数据驱动全局特征提取的改进髓鞘水成像在多发性硬化患者中的应用

The predominant technique for quantifying myelin content in the white matter is multicompartment analysis of MRI's T2relaxation times (mcT2 analysis). The process of resolving the T2spectrum at each voxel, however, is highly ill-posed and r...
Reduced expression of fMRI subsequent memory effects with increasing severity across the Alzheimer's disease risk spectrum [0.03%]

In functional magnetic resonance imaging (fMRI) studies, episodic memory is commonly investigated with the subsequent memory paradigm in which brain activity is recorded during encoding and analyzed as a function of subsequent remembering a...

Steady-State Visually Evoked Potentials (SSVEPs) manifest as a sustained rhythmic activity that can be observed in surface electroencephalography (EEG) in response to periodic visual stimuli, commonly referred to as flickers. SSVEPs are wid...
BOLD fMRI responses to amplitude-modulated sounds across age in adult listeners [0.03%]

Age-related alterations in the auditory system have been suggested to affect the processing of temporal envelope amplitude modulations (AM) at different levels of the auditory hierarchy, yet few studies have used functional magnetic resonan...
Removing scanner effects with a multivariate latent approach: A RELIEF for the ABCD imaging data? [0.03%]
基于多变量潜在方法的扫描仪效应去除：对ABCD影像数据的一种RELIEF？

Scan site harmonization is a crucial part of any neuroimaging analysis when data have been pooled across different study sites. Zhang and colleagues recently introduced the multivariate harmonization method RELIEF (REmoval of Latent Inter-s...
Respiration recording for fMRI: breathing belt versus spine coil sensor [0.03%]

Physiological signals such as pulse and respiration strongly contribute to non-neuronal signal change of the blood oxygenation level-dependent (BOLD) contrast in functional magnetic resonance imaging (fMRI). This has been observed not only ...
Mental rotation-related neural interactions between gender and cognitive strategy [0.03%]

A long-standing history of research has focused on the differences between men and women in cognitive tasks, including that men would be more accurate and faster than women in mental rotation (MR). This advantage suggests that men would use...
