Tractography based on diffusion-weighted MRI (dMRI) is the predominant in vivo method for mapping the brain's white matter. However, it is also one of the most computationally demanding steps in neuroimaging data analysis-requiring the gene...
Functionally distinct alpha components are differentially modulated by attention and affect behavior [0.03%]
功能不同的alpha成分由注意调节并影响行为

Gamze Bilgen et al.
Alpha oscillations (~10 Hz) have been hypothesized to gate information flow in the brain by inhibiting task-irrelevant and disinhibiting task-relevant processing. Recent work using independent component analysis (ICA) showed that functional...

Normative modeling is increasingly used to characterize typical growth trajectories and identify atypical neurodevelopment, including early brain development using magnetic resonance imaging (MRI) acquired before birth. Recent work has emph...
Decision processes underlying effort avoidance and their relationship with metacognition [0.03%]
决策过程中的努力回避及其与元认知的关系

Kazuki Yoshida et al.
Effort-based decision making relies on cost-benefit computations that require individuals to evaluate expected rewards against the effort needed to obtain them. However, the temporal dynamics underlying the neural processing of reward and e...
Fine-scale individualized gyral folding-based cortical similarity networks reveal distinct organizational patterns in Alzheimer's disease and Lewy body dementia [0.03%]
基于细粒度个体化脑回折叠的大脑皮层相似性网络揭示了阿尔茨海默病和路易体痴呆的不同组织模式

Minheng Chen et al.
Alzheimer's disease (AD) and Lewy body dementia (LBD) are common neurodegenerative dementias with overlapping clinical presentations, making differential diagnosis challenging. While structural magnetic resonance imaging (MRI) has revealed ...
Acting upon threat: Electrocortical, autonomic, and oculomotor responses in anticipation of avoidable and inevitable threats [0.03%]

Attentive immobility is a defensive state that prepares organisms for adaptive responses to imminent threats. In humans, it has been associated with a multimodal pattern of heart rate bradycardia, elevated skin conductance, freezing of gaze...
Beyond the canonical HRF: Flexible temporal modeling reveals unconstrained BOLD profiles during naturalistic viewing [0.03%]
超越经典HRF：灵活的时间模式揭示了自然视图下不受限制的BOLD轮廓

Naturalistic stimuli, such as movies and narratives, are increasingly used in cognitive neuroscience to map cognitive and affective processes onto brain activity measured with functional MRI (fMRI). Features extracted from movies span multi...
When the inner clock fades: Interoceptive decline and consolidation of phase resetting in cortical rhythms by cardiac events underlie healthy lifespan aging [0.03%]
当内心时钟消逝：内在感知力下降和心脏事件对皮层节律相位重置的巩固导致健康寿命衰老

The brain continuously integrates signals from the external environment along with internal bodily cues to support adaptive cognition and homeostasis. Among these, multiple visceral rhythms, such as respiration, circadian fluctuations, and ...
SUITPy: A Python-based toolbox for the analysis of cerebellar functional and anatomical imaging data across the human lifespan [0.03%]
SUITPy：一个基于Python的工具箱，用于分析人类一生中小脑功能和结构成像数据

Yaping Wang et al.
The human cerebellum plays a central role in motor, emotional, and cognitive functions, and is implicated in many brain disorders. To improve the analysis of functional and anatomical imaging from the cerebellum, we introduce SUITPy, an imp...
Atypical low-frequency and high-frequency neural entrainment to rhythmic audiovisual speech in adults with dyslexia [0.03%]
