Research on node properties of resting-state brain functional networks by using node activity and ALFF

Multimedia Tools and Applications, 2017
Human brain functional networks have some attractive topological properties in anatomical space, whereas relatively few literatures to discuss the local properties of brain networks. In this paper, a method for judging nodes properties of resting-state brain functional networks is proposed based on node activity and Amplitude of Low Frequency ...

Frequency-Dependent Changes in Wavelet-ALFF in Patients With Acute Basal Ganglia Ischemic Stroke: A Resting-State fMRI Study

open access: yesNeural Plasticity
Background and Purpose: Motor impairment is a common occurrence in patients with acute basal ganglia (BG) ischemic stroke (ABGIS). However, the underlying mechanisms of poststroke motor dysfunction remain incompletely elucidated. In this study, we employed multifrequency band wavelet transform‐based amplitude of

Alterations in resting-state ALFF and functional connectivity linked to implicit and explicit suicidal ideations in depression

Behavioural Brain Research
This study aimed to explore the neurobiology of implicit and explicit suicidal ideation (SI) in depression. Seventy-four patients with major depressive disorder (MDD) along with 74 age- and gender- matched healthy controls were enrolled. The Death/Suicide implicit association test (D/S-IAT), the explicit Beck Scale for Suicidal Ideation (BSSI), and ...

ALFF changes in brain areas of human with high myopia revealed by resting-state functional MRI

2010 3rd International Conference on Biomedical Engineering and Informatics, 2010
Objective: To study the changes of amplitude of low-frequency fluctuation (ALFF) of the resting-fMRI in brain areas of human with high myopia. Methods: Twenty graduate students with high myopia and twenty ones with normal vision underwent two resting-state fMRI scanning sessions, one for eyes-open (EO) with no fixation and one for eyes-closed (EC ...

Sensorimotor Network ALFF Markers as Prognostic Indicators of Cervical Spondylotic Myelopathy Post-Decompression Surgery Outcomes

Journal of Clinical Neuroscience
To investigate the prognostic value of amplitude of low-frequency fluctuations (ALFF) within the sensorimotor network (SMN) in patients with cervical spondylotic myelopathy (CSM) following decompression surgery.Eighty-three presurgical CSM patients (pre-CSM), 60 of the same group followed-up 3 months after decompression surgery (post-CSM) and 83 ...

Dynamic ALFF and dynamic Reho in bipolar disorder: Genetic links and predictive value for diagnosis and therapy

Asian Journal of Psychiatry
Alterations in resting-state brain activity in bipolar disorder (BD) and their pharmacological response remain unclear. This study investigated dynamic local brain activity, assessed the discriminative ability of dALFF and dReHo, and explored related transcriptomic correlates.Resting-state fMRI and clinical data were obtained from 77 BD patients (with ...

Multimodal imaging biomarkers in intractable temporal lobe Epilepsy: A comparative study of structural–functional coupling and ALFF

Epilepsy & Behavior
Intractable temporal lobe epilepsy (ITLE) remains a clinical challenge due to its resistance to standard treatments and its profound impact on cognitive function. Multimodal neuroimaging techniques offer potential biomarkers for diagnosis and treatment monitoring, yet comparative evaluations of their utility remain limited.We conducted a longitudinal ...
