OBJECTIVES Severe hepatic encephalopathy gives rise to asterixis, a striking motor symptom also called flapping tremor, which is characterized by a sudden ceasing of muscle tone in all muscles of a limb. In this study, we aimed at scrutinizing the cortical activation associated with asterixis and unraveling the underlying pathophysiological mechanisms. MATERIAL AND METHODS We recorded simultaneously neural activity with magnetoencephalography (MEG) and muscle activity with surface EMG in nine… CONTINUE READING
