Hippocampal fractional amplitude of low‐frequency fluctuation and functional connectivity changes in premenstrual syndrome

Journal of Magnetic Resonance Imaging, 2017
PurposeTo investigate differences in hippocampal activity between premenstrual syndrome (PMS) patients and healthy controls, to elucidate the neural mechanisms of PMS.Materials and MethodsTwenty female patients with PMS (PMS group) and 21 healthy controls (HC group) underwent a single‐shot gradient‐recalled echo planar imaging (EPI) sequence scan ...

Fractional amplitude of low-frequency fluctuation alterations in patients with cervical spondylotic myelopathy: a resting-state fMRI study

Neuroradiology
We sought to use the fractional amplitude of low-frequency fluctuation (fALFF) method to investigate the changes in spontaneous brain activity in CSM patients and their relationships with clinical features.We recruited 20 patients with CSM, and 20 healthy controls (HCs) matched for age, sex, and education status.

Fractional amplitude of low-frequency fluctuations and gray matter volume alterations in patients with bipolar depression

Neuroscience Letters, 2020
We used fractional amplitude of low-frequency fluctuations (fALFF) and gray matter volume (GMV) jointly to explore the mechanism of brain function and structure in unmedicated patients with bipolar disorder (BD).Thirty first episode drug-naive patients with and thirty healthy controls (HCs) were recruited in this study; All the subjects underwent ...

Fractional Amplitude of Low-Frequency Fluctuation and Voxel-Mirrored Homotopic Connectivity in Patients with Persistent Postural-Perceptual Dizziness: Resting-State Functional Magnetic Resonance Imaging Study

Brain Connectivity
Purpose: Persistent postural-perception dizziness (PPPD) is a chronic subjective form of dizziness characterized by the exacerbation of dizziness with active or passive movement, complex visual stimuli, and upright posture. Therefore, we aimed to analyze

Analysis of the differences in brain function response after acupuncture and moxibustion at Zúsānlĭ (足三里ST36) in the patients with functional dyspepsia based on fractional amplitude of low frequency fluctuation of rest functional magnetic resonance imaging

World Journal of Acupuncture - Moxibustion, 2021
Objective to explore the differences in the central response after acupuncture and moxibusbution at Zusānlĭ (足三里ST36) in treatment of functional dyspepsia (FD) based on the analysis of fractional amplitude of low frequency fluctuation (fALFF) of resting ...

Association Between Fractional Amplitude of Low-Frequency Spontaneous Fluctuation and Degree Centrality in Children and Adolescents

Brain Connectivity, 2019
The fractional amplitude of low-frequency fluctuations (fALFFs) of the BOLD signal have been successfully applied as exploratory tools in neuroimaging. This metric has been useful in mapping brain functional changes in many clinical populations. However, little is known about the neurophysiological correlates of fALFF. This study aimed at demonstrating

Altered fractional amplitude of low frequency fluctuation in premenstrual syndrome: A resting state fMRI study

Journal of Affective Disorders, 2017
Premenstrual syndrome (PMS) is becoming highly prevalent among female and is characterized by emotional, physical and behavior symptoms. Previous evidence suggested functional dysregulation of female brain was expected to be involved in the etiology of PMS.

Fractional amplitude of low-frequency fluctuation changes in functional dyspepsia: A resting-state fMRI study

Magnetic Resonance Imaging, 2013
Recently, there is an increasing interest in the study of the role of brain dysfunction in the pathogenesis of symptoms of functional dyspepsia (FD). More specifically, abnormal brain activities in patients with FD during the resting state have been proven by several positron emission tomography (PET) studies.

Altered Fractional Amplitude of Low Frequency Fluctuations in Unmedicated Female Patients with Obsessive-Compulsive Disorder

2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018
A number of resting-state functional magnetic resonance imaging (rs-fMRI) studies indicate dysfunction of large-scale brain networks underlying the pathophysiology of obsessive-compulsive disorder (OCD). Recent epidemiology studies show that the prevalence of female OCD patients is higher than that of males.

Associations of brain entropy (BEN) to cerebral blood flow and fractional amplitude of low-frequency fluctuations in the resting brain

Brain Imaging and Behavior, 2018
Entropy is a fundamental trait of human brain. Using fMRI-based brain entropy (BEN) mapping, interesting findings have been increasingly revealed in normal brain and neuropsychiatric disorders. As BEN is still relatively new, an often-raised question is how much new information can this measure tell about the brain compared to other more established ...
