    Abnormal Baseline Brain Activity in Patients with Pulsatile Tinnitus: A Resting-State fMRI Study by Lv Han, Liu Zhaohui, Yan Fei, Li Ting, Zhao Pengfei, Du Wang, Dong Cheng, Guo Pengde, Han Xiaoyi, Wang Xiao, Li Rui, Wang Zhenchang

    Published 2014-01-01
    “…The aim of this study is to investigate whether altered baseline brain activity presents in patients with PT using resting-state functional magnetic resonance imaging (rs-fMRI) technique. The present study used unilateral PT patients (n=42) and age-, sex-, and education-matched normal control subjects (n=42) to investigate the changes in structural and amplitude of low-frequency (ALFF) of the brain. …”
