REST: A Toolkit for Resting-State Functional Magnetic Resonance Imaging Data Processing
Xiaowei Song,Zhang-Ye Dong,Xiangyu Long,Su-Fang Li,Xi-Nian Zuo,Chaozhe Zhu,Yong He,Chao-Gan Yan,Yu-Feng Zang,Yu-Feng Zang +9 more
TL;DR: A toolkit for the analysis of RS-fMRI data, namely the RESting-state fMRI data analysis Toolkit (REST), which was developed in MATLAB with graphical user interface (GUI).
Journal ArticleDOI
An improved approach to detection of amplitude of low-frequency fluctuation (ALFF) for resting-state fMRI: fractional ALFF.
Qihong Zou,Chaozhe Zhu,Yihong Yang,Xi-Nian Zuo,Xiangyu Long,Xiangyu Long,Qingjiu Cao,Yufeng Wang,Yu-Feng Zang,Yu-Feng Zang +9 more
TL;DR: The proposed fractional ALFF (fALFF) approach improved the sensitivity and specificity in detecting spontaneous brain activities and the brain areas within the default mode network including posterior cingulate cortex, precuneus, medial prefrontal cortex and bilateral inferior parietal lobule had significantly higher fALFF than the other brain areas.
Journal ArticleDOI
Amplitude of low frequency fluctuation within visual areas revealed by resting-state functional MRI.
Hong Yang,Xiangyu Long,Yihong Yang,Hao Yan,Chaozhe Zhu,Xiang-Ping Zhou,Yu-Feng Zang,Yu-Feng Zang,Qiyong Gong,Qiyong Gong +9 more
TL;DR: The finding of the distinct ALFF difference between EO and EC in the visual cortex implies that the ALFF may be a novel biomarker for physiological states of the brain.
Journal ArticleDOI
Functional segmentation of the brain cortex using high model order group PICA
Vesa Kiviniemi,Tuomo Starck,Jukka Remes,Xiangyu Long,Xiangyu Long,Juha Nikkinen,Marianne Haapea,Marianne Haapea,Juha Veijola,Juha Veijola,Irma Moilanen,Matti Isohanni,Yu-Feng Zang,Osmo Tervonen +13 more
TL;DR: It is concluded that the high model order ICA of the group BOLD data enables functional segmentation of the brain cortex and enables new approaches to causality and connectivity analysis with more specific anatomical details.
Journal ArticleDOI
Regional homogeneity changes in patients with Parkinson's disease.
TL;DR: It is demonstrated that neural activity in the resting state is changed in patients with PD, secondary to dopamine deficiency, and related to the severity of the disease.
