Highlights

  • Mild disturbances in motor function are common features of schizophrenia that impact patient quality of life greatly. 
  • Abnormalities in sensorimotor processing can be observed in schizophrenia patients using simple magnetoencephalography (MEG) paradigm.
  • Published in Neuroimage Clinical.

Summary

  1. Electrophysiological data in healthy people shows a decrease in beta band oscillations in the sensorimotor cortex during execution of movements, suggesting event-related beta desynchronization (ERBD) in this part of the brain. 
  2. ERBD is followed by post-movement beta rebound (PMBR), which is characterized by an increase above the baseline for a short while after the movement. 
  3. Peak-to-peak change in the amplitude from ERBD to PMBR is comparatively lower in schizophrenia patients. 
  4. MEG studies can be used to evaluate motor function in schizophrenia patients.
