Mind-Body Practice Changes Fractional Amplitude of Low Frequency Fluctuations in Intrinsic Control Networks [PDF]

open access: yesFrontiers in Psychology, 2017
Cognitive control impairment is a typical symptom largely reported in populations with neurological disorders. Previous studies have provided evidence about the changes in cognitive control induced by mind-body training.

Specific frequency bands of amplitude low-frequency fluctuations in memory-related cognitive impairment: predicting Alzheimer’s disease [PDF]

open access: yesADMET and DMPK, 2015
Resting-state functional magnetic resonance imaging was utilized to measure the amplitude low frequency fluctuations (ALFF) in human subjects with Alzheimer’s disease (AD) and normal control (NC).

Fractional amplitude of low-frequency fluctuations during music-evoked autobiographical memories in neurotypical older adults [PDF]

open access: yesFrontiers in Neuroscience
IntroductionResearchers have shown that music-evoked autobiographical memories (MEAMs) can stimulate long-term memory mechanisms while requiring little retrieval effort and may therefore be used in promising non-pharmacological interventions to mitigate ...

Amplitude of low-frequency fluctuations in multiple-frequency bands in acute mild traumatic brain injury [PDF]

open access: yesFrontiers in Human Neuroscience, 2016
Functional disconnectivity during the resting state has been observed in mild traumatic brain injury (mTBI) patients during the acute stage. However, it remains largely unknown whether the abnormalities are related to specific frequency bands of the low ...

Differentiating Melancholic and Non-melancholic Major Depressive Disorder Using Fractional Amplitude of Low-Frequency Fluctuations [PDF]

open access: yesFrontiers in Psychiatry, 2022
BackgroundMelancholic major depressive disorder (MDD) is a network-based brain disorder. However, whether or not network-based changes can be applied to differentiate melancholic (MEL) from non-melancholic (NMEL) MDD remains unclear.MethodsThirty-one MEL

Frequency-Specific Alterations of Fractional Amplitude of Low-Frequency Fluctuations in Adult-Onset Hypothyroidism

open access: yesJournal of Integrative Neuroscience, 2023
Background: The neuropathophysiological mechanisms of brain damage underlying hypothyroidism remain unclear. Fractional amplitude of low-frequency fluctuations (fALFF) has been established as a reliable indicator for investigation of abnormal spontaneous

Altered dynamic amplitude of low-frequency fluctuations in patients with postpartum depression [PDF]

open access: yesBehavioural Brain Research, 2022
Postpartum depression (PPD) is a common mood disorder with increasing incidence year by year. However, the dynamic changes in local neural activity of patients with PPD remain unclear. In this study, we utilized the dynamic amplitude of low-frequency fluctuation (dALFF) method to investigate the abnormal temporal variability of local neural activity ...

Five negative symptom domains are differentially associated with resting state amplitude of low frequency fluctuations in Schizophrenia. [PDF]

open access: yesPsychiatry Res Neuroimaging, 2023
This study examined associations between resting-state amplitude of low frequency fluctuations (ALFF) and negative symptoms represented by total scores, second-order dimension (motivation and pleasure, expressivity), and first-order domain (anhedonia ...
