Amplitude of low-frequency fluctuation after taste exposure revealed by resting-state fMRI

Physiology & Behavior, 2023
Taste perception has been deeply explored from the behavioural level to delineating neural mechanisms. However, most previous studies about the neural underpinnings of taste perception have focused on task-related brain activation. Notably, evidence indicates that task-induced brain activation often involves interference from irrelevant task materials ...

Disrupted amplitude of low-frequency fluctuations and causal connectivity in Parkinson’s disease with apathy

Neuroscience Letters, 2018
Apathy is a common non-motor symptom in Parkinson's disease (PD). We aimed to explore its associated neural substrates changes via amplitude of low-frequency fluctuations (ALFF) and granger causality analysis (GCA). Resting-state functional magnetic resonance imaging (rs-fMRI) scans were performed in 20 PD patients with apathy (PD-A), 22 PD patients ...

Abnormal Amplitude of Low-Frequency Fluctuations of Intrinsic Brain Activity in Alzheimer's Disease

Journal of Alzheimer's Disease, 2014
We used resting-state functional magnetic resonance imaging to measure the amplitude of low-frequency fluctuations (ALFF) of intrinsic brain activity in 23 patients with moderate Alzheimer's disease (AD) and 27 age- and gender-matched healthy controls. Two different frequency bands were analyzed (slow-5:0.01–0.027 Hz; slow-4:0.027–0.073 Hz).

Frequency-dependent alterations in the amplitude of low-frequency fluctuations in social anxiety disorder

Journal of Affective Disorders, 2015
Recent studies on resting-state functional magnetic resonance imaging (fMRI) have found an abnormal temporal correlation between low-frequency oscillations (LFO) in social anxiety disorder (SAD). However, alterations in the amplitudes of these LFO remain unclear.This study included 20 SAD patients and 20 age-, gender-, and education-matched healthy ...

Dynamic analysis of amplitude of low-frequency fluctuation in children with growth hormone deficiency

Behavioural Brain Research
Growth hormone (GH) affects brain activities and promotes growth and development. GH is a peptide hormone secreted by the anterior pituitary gland and is tied to behavior and cognitive function. Growth hormone deficiency (GHD) is the most common type of pathological short stature in children.
