title: [Auditory hallucinations. Nomenclature and classification].
abstract: BACKGROUND
  We are rapidly increasing our knowledge about the correlates of auditory hallucinations. If we are to understand and integrate this new knowledge it is essential that the nomenclature for this special area is clear and unambiguous.
  
  
  OBJECTIVE
  To review and to re-evaluate the concept of auditory hallucinations belonging to classical psychiatry.
  
  
  METHODS
  Relevant data were collected from books, PubMed, Embase and the Cochrane Library.
  
  
  RESULTS
  On the basis of our findings we present different classifications for auditory hallucinations.
  
  
  CONCLUSIONS
  Our review emphasises the need for a re-appraisal of these concepts, clearer definitions and an improved nomenclature. These will make it easier to set up, conduct and interpret neurological studies of these frequently occurring phenomena.
