Psychotropic Drugs and Experimental Psychiatry

Academic Address
  • Jean Delay


Progress in psychopharmacology has made available to clinicians a whole series of psychotropic drugs capable of influencing behavior in different directions. The word “psychotropic” is useful since it identifies in a general fashion a whole group of natural or artificially occurring substances that modify behavior. Whether they depress, stimulate, or deviate the mental energies or produce a state of stimulation, relaxation, or delusion, it is possible to classify them clinically in a rather simple fashion, at least until a more scientific classification becomes possible which will allow one to correlate psychological changes with chemical formulas and to selectively localize their site of action in the brain and their intracerebral metabolism.
