Objectives
Narrative objectives1
Currently, EEG monitor is widely used to assess the hypnotic level. These monitors used 1-2 channels of EEG obtained from frontal leads, and often interfered by EMG or other artifacts. The aim of this study is to obtain multi-channels of EEG, remove artifacts by ICA, and then observe the changes of reconstructed EEG signal during the recovery from anesthesia.
