Altered resting-state FMRI signals in acute stroke patients with ischemic penumbra. [PDF]
PLoS ONE, 2014 Identifying the ischemic penumbra in acute stroke subjects is important for the clinical decision making process. The aim of this study was to use resting-state functional magnetic resonance singal (fMRI) to investigate the change in the amplitude of low-

Amplitude of Low-Frequency Oscillations in Major Depressive Disorder With Childhood Trauma
Frontiers in Psychiatry, 2021 Major Depressive Disorder (MDD) with childhood trauma is one of the functional subtypes of depression. Frequency-dependent changes in the amplitude of low-frequency fluctuations (ALFF) have been reported in MDD patients. However, there are few studies on

Alterations of Spontaneous Brain Activity in Hemodialysis Patients
Frontiers in Human Neuroscience, 2020 Cognitive impairment is prevalent in hemodialysis end-stage renal disease (ESRD) patients. It might be associated with poor prognosis. Nevertheless, the underlying mechanisms have not been completely clarified.

Resting-State Neural-Activity Alterations in Subacute Aphasia after Stroke
Brain Sciences, 2022 Linguistic deficits are frequent symptoms among stroke survivors. The neural mechanism of post-stroke aphasia (PSA) was incompletely understood. Recently, resting-state functional magnetic resonance imaging (rs-fMRI) was widely used among several ...

BOLD-ALFF (A), CBF-mean (B), and CBF-ALFF (C) for EC compared to EO using NIDA data.
, 2015 The delta (i.e., EC minus EO) of BOLD-ALFF (D), CBF-mean (E) and CBF-ALFF (F) of three typical voxels from each subject is shown (PSC: primary somatosensory cortex, with peak t value at [–44, 22,41] in Fig.
