Association of impaired EEG mu wave suppression negative symptoms and social functioning in biological motion processing in first episode of psychosis

摘要

BackgroundEvent related desynchronization (ERD) of mu waves, or mu suppression, over sensorimotor cortex has been observed in response to self-generated movement, viewing movement, or imaging movement. Mu suppression is especially pronounced when the movement has social relevance and is being generated by a biological entity indicating successful social adaptation. And since social adaptation problems are common in schizophrenia, the authors designed a study to test mu wave suppression in a first episode of psychosis population.
