Fractional Amplitude of Low-Frequency Fluctuations (fALFF) in Post-Stroke Depression [PDF]
NeuroImage: Clinical, 2017 Depression is a common outcome following stroke, associated with reduced quality of life and poorer recovery. Despite attempts to associate depression symptoms with specific lesion sites, the neural basis of post-stroke depression remains poorly understood.

Frontiers in Neuroscience, 2022 BackgroundPrevious neuroimaging studies have mostly focused on changes in static functional connectivity in patients with chronic insomnia (CI). Features of dynamic brain activity in patients with CI have rarely been described in detail. The present study investigated changes in dynamic intrinsic brain activity in patients with CI by dynamic fractional

Abnormal fractional Amplitude of Low-Frequency Fluctuation in chronic ketamine users
Psychiatry Research: Neuroimaging, 2022Ketamine has become a major substance of abuse worldwide. Nevertheless, The long-term effects of ketamine use on intrinsic spontaneous neural activity remain unknown.In the present study, rs-fMRI was used to explore whether chronic ketamine use changes the intrinsic spontaneous neural activity, and whether the intrinsic spontaneous neural activity ...

The Relevance of Fractional Amplitude of Low-Frequency Fluctuation to Interference Effect [PDF]
Behavioural Brain Research, 2016 Growing evidence has indicated a potential connection between resting-state functional magnetic resonance imaging (RS-fMRI) signal and cognitive performance. However, the relationship between intrinsic neural activity and behavioral interference effect on cognitive control has been poorly understood. In the present study, seventy-eight healthy subjects

An Improved Approach to Detection of Amplitude of Low-Frequency Fluctuation (ALFF) for Resting-State fMRI: Fractional ALFF [PDF]
Journal of Neuroscience Methods, 2008 Most of the resting-state functional magnetic resonance imaging (fMRI) studies demonstrated the correlations between spatially distinct brain areas from the perspective of functional connectivity or functional integration. The functional connectivity approaches do not directly provide information of the amplitude of brain activity of each brain region ...

Clinical Neurophysiology, 2017
To explore brain activity in AD with depression (D-AD) based on fractional amplitude of low-frequency fluctuation (fALFF).Twenty-two D-AD and 21 AD without depression patients (nD-AD) were examined by magnetic resonance imaging during resting state. Neuropsychiatric Inventory and Hamilton Depression Rating Scale were employed to assess the severity of ...

Fractional amplitude of low-frequency fluctuations of BOLD signal in schizophrenia
2015 23rd Iranian Conference on Electrical Engineering, 2015Over 1% of the world population suffer from schizophrenia, which is a mental and hereditary disorder. Diagnosis of this disorder is now based mainly on the clinical symptoms. As the first study in Iran, we used magnetic resonance imaging (MRI) technique to study biomarkers of schizophrenia that are detectable in resting state functional MRI (fMRI).

Value of Frequency Domain Resting-State Functional Magnetic Resonance Imaging Metrics Amplitude of Low-Frequency Fluctuation and Fractional Amplitude of Low-Frequency Fluctuation in the Assessment of Brain Tumor-Induced Neurovascular Uncoupling [PDF]
Brain Connectivity, 2017 The aim of this study was to explore whether the phenomenon of brain tumor-related neurovascular uncoupling (NVU) in resting-state blood oxygen level-dependent functional magnetic resonance imaging (BOLD fMRI) (rsfMRI) may also affect the resting-state fMRI (rsfMRI) frequency domain metrics the amplitude of low-frequency fluctuation (ALFF) and ...
