title: [The characteristics of opioid receptors distributed in the neurons of habenula].
abstract: OBJECTIVE
  To explore the types of receptors distributed in MHb and LHb.
  
  
  METHODS
  Recording the currents of potassium channels in Hb neurons isolated from the rats 10-15 days after birth. To distinguish the types of receptors distributed in MHb and LHb by using the agonists of mu receptor DAMGO, and sigma receptor DPDPE.
  
  
  RESULTS
  Two types of current of K+ channels were recorded, the transient rectifier and delayed rectifier potassium channels. DAMGO or DPDPE increased the intensity of current of K+ channels.
  
  
  CONCLUSIONS
  In MHb there was a higher density of sigma receptor, and in LHb a higher density of mu receptor distributed.
