title: Facial expression recognition and subthalamic nucleus stimulation.
abstract: BACKGROUND
  Deep brain stimulation (DBS) of the subthalamic nucleus (STN) improves motor signs in Parkinson's disease. However, clinical studies suggest that DBS of the STN may also affect cognitive and emotional functions.
  
  
  OBJECTIVE
  To study the impact of STN stimulation in Parkinson's disease on perception of facial expressions.
  
  
  RESULTS
  There was a selective reduction in recognition of angry faces, but not other expressions, during STN stimulation.
  
  
  CONCLUSIONS
  The findings may have important implications for social adjustment in these patients.
