The research focuses on establishing a system for detecting loss of consciousness, developing clinical prognostic and awakening-related brain function testing criteria.

A framework for the acquisition of neural features, feature selection and mechanism analysis of consciousness deficits in patients with acute and prolonged disorders of consciousness(DOC). Based on the multimodal data of three types of patients with DOC, the investigators established a comprehensive scientific collection of brain function features of acute and prolonged consciousness disorders; Revealed the key neural nodes and circuits of consciousness deficits, and elucidated the neural mechanisms of consciousness deficits in patients with prolonged consciousness disorders from EEG time-frequency-spatial features;
