Journal ArticleDOI
Abnormal functional connectivity of the amygdala is associated with depression in Parkinson's disease
TL;DR: Depressive patients in the depressed PD group showed increased connectivity between limbic regions and decreased connectivity between the corticolimbic networks, which may reflect impaired high‐order cortical regulatory effects on the emotion‐related limbic areas, which could lead to mood dysregulation.
Journal ArticleDOI
Frequency specificity of regional homogeneity in the resting-state human brain.
Xiaopeng Song,Yi Zhang,Yijun Liu +2 more
TL;DR: The results showed that ReHo in cortical areas were higher and more frequency-dependent than those in the subcortical regions, and the distinct frequency-specific ReHo properties of different brain areas may arise from the assorted cytoarchitecture or synaptic types in these areas.
Journal ArticleDOI
Altered Resting-State Brain Activity and Connectivity in Depressed Parkinson's Disease.
TL;DR: In this paper, the authors examined disrupted spontaneous local brain activities and functional connectivities that underlie the depression in Parkinson's disease and found that higher local activities in the left MCC were associated with increased functional connections between the MCC and the nodes of the default mode network in PD.
Journal ArticleDOI
Mitochondrial dysfunction, oxidative stress, neuroinflammation, and metabolic alterations in the progression of Alzheimer's disease: A meta-analysis of in vivo magnetic resonance spectroscopy studies.
Tao Song,Xiaopeng Song,Chenyawen Zhu,Regan E. Patrick,Miranda Skurla,Isabella Santangelo,Morgan Green,David G. Harper,Boyu Ren,Brent P. Forester,Dost Öngür,Fei Du +11 more
TL;DR: In this paper, the authors used meta-analyses to identify patterns of brain metabolic alterations in mild cognitive impairment (MCI) and Alzheimer's disease (AD) and found that the hippocampus shows the strongest alterations in most of these metabolites.
Journal ArticleDOI
Altered resting-state hippocampal and caudate functional networks in patients with obstructive sleep apnea.
Xiaopeng Song,Bhaswati Roy,Daniel W. Kang,Ravi S. Aysola,Paul M. Macey,Mary A. Woo,Frisca L. Yan-Go,Ronald M. Harper,Rajesh Kumar +8 more
TL;DR: Examination of resting‐state functional connectivity of the hippocampus and caudate to other brain areas in OSA relative to control subjects connected these changes to mood and neuropsychological scores to identify contributions to cognitive and emotional deficits.
