Narrative comprehension is a fundamental cognitive skill that involves the coordination of different functional brain regions. We develop a spectral graphical model with model averaging to study the connectivity networks underlying these br...
Distinction in coherent neural network between resting and working brain states [0.03%]
休息与工作大脑状态在相干神经网络中的区分

Small-world networks, according to Watts and Strogatz, are a class of networks that are "highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs." These characteristics result in networks with...
Magnetic resonance imaging and graph theoretical analysis of complex brain networks in neuropsychiatric disorders [0.03%]
神经精神疾病中的磁共振成像和图论脑网络分析

Neurological and psychiatric disorders disturb higher cognitive functions and are accompanied by aberrant cortico-cortical axonal pathways or synchronizations of neural activity. A large proportion of neuroimaging studies have focused on ex...
A sliding time-window ICA reveals spatial variability of the default mode network in time [0.03%]
时间窗滑动ICA揭示了默认模式网络在时间上的空间变化性

Vesa Kiviniemi et al.
Recent evidence on resting-state networks in functional (connectivity) magnetic resonance imaging (fcMRI) suggests that there may be significant spatial variability of activity foci over time. This study used a sliding time window approach ...
MRI diffusion indices sampled along streamline trajectories: quantitative tractography mapping [0.03%]

Abstract Several useful tractography-derived maps have recently been introduced, such as track density imaging (TDI) and the average pathlength map (APM). Here, an extension to these techniques is introduced by sampling diffusion indices al...
Object working memory performance depends on microstructure of the frontal-occipital fasciculus [0.03%]
对象工作记忆的表现依赖于顶枕束的微结构

MRI structural connectivity, disruption of primary sensorimotor pathways, and hand function in cerebral palsy [0.03%]
脑瘫的结构连接性、初级感觉运动通路中断及手功能受损
Stephen Rose,Andrea Guzzetta,Kerstin Pannek et al.
Stephen Rose et al.
Brain injury and subsequent plasticity of sensory and corticospinal pathways play an integral role in determining paretic hand function in congenital hemiplegia. There is limited knowledge regarding the relationship between the disruption o...
The brain as a complex system: using network science as a tool for understanding the brain [0.03%]
作为理解大脑的工具的网络科学：复杂系统视角下的大脑结构与功能研究

Qawi K Telesford et al.
Although graph theory has been around since the 18th century, the field of network science is more recent and continues to gain popularity, particularly in the field of neuroimaging. The field was propelled forward when Watts and Strogatz i...

Great effort has been dedicated to mapping the functional architecture of the brain in health and disease. The neural centers that support cognition and behavior are the "hubs" defining the salient geographic landmarks of the cerebral topog...
