title: [Effects of fastigial nucleus stimulation on crucial cardiovascular physiological parameters].
abstract: OBJECTIVE
  In order to study the effect of fastigial nucleus stimulation (FNS) on human cardiovascular system, the photo plethysmogram (PPG) affected by FNS were recorded and analyzed.
  
  
  METHODS
  Thirty volunteers' pulse signals were recorded before, during and after the FNS, and 5 PPG characteristics, such as H, Slope, and K were extracted. Changes of each characteristic in three stages were analyzed contrastive and based on which physiological changes caused by FNS were described.
  
  
  RESULTS
  The pulse wave showed sensitive on-going short-term changes during the FNS.
  
  
  CONCLUSIONS
  Changes of characteristics indicates that FNS results in ongoing short-term changes of some physiological parameters such as peripheral blood flow and peripheral resistance.
