[Fractional amplitude of low-frequency fluctuations in retinal vein occlusion: a resting-state fMRI study].

[Zhonghua yan ke za zhi] Chinese journal of ophthalmology, 2020
Objective: To investigate the altered spontaneous brain activity in patients with retinal vein occlusion (RVO) during the resting state. Methods: A case-control study. Forty-five patients with RVO [24 males and 21 females; age, (51.24±5.86) years] diagnosed from May 2018 to July 2019 in Renmin Hospital of Wuhan University were recruited in the RVO ...

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.

Cerebral change of the fractional amplitude of low frequency fluctuation (fALFF) in a harmaline-induced tremor rat model

ISMRM Annual Meeting
Motivation: While the harmaline-induced tremor rat model is based on cerebellar circuitry, its impact on the cerebrum remains unknown. Goal(s): Assess the cerebral activity in harmaline-induced rat tremor model. Approach: Resting-state fMRI scan of the harmaline-administered SD rat.
