Radionuclide functional and molecular imaging in rapid eye movement sleep behavior disorder / 中华核医学与分子影像杂志

Rapid eye movement sleep behavior disorder (RBD) is a condition characterized by rap id eye movement sleep without atonia and with complex behaviors associated with dreams.Numerous studies have revealed that idiopathic RBD is the prodromal manifestation of neurodegenerative disorders,especially those mediated by α-synuclein.The structural and functional imaging of RBD,including transcranial sonog raphy (TCS),MRI,SPECT,PET,are increasingly becoming the hot issues.This review summarizes the radionuclide imaging in RBD,which may be one of the most promising modalities to detect the biomarkers for early diagnosis of neurodegenerative disorders.

Research advance of implementing schemes of cochlear implant and its speech processing algorithms / 生物医学工程学杂志

This paper introduces the implementing schemes of cochlear implants, signal processing strategies and current state-of-the-art implant processors. The paper mainly discusses the key questions which would come up in designing cochlear implant system. Eventually we express our opinions about the development and further research of cochlear implants.
