[The role of the neurochemical mechanisms of the medial raphe nucleus in anxiety states formed by various aversive actions].

The experimental studies on rats with microinjections of a number of monoamines and amino acids into median raphe nuclei showed functional importance of neither dofamine nor glutamat but of 5-HT or 5-HT- and GABA-ergic mechanisms of median raphe nuclei formation in anxiety states formed by aversive actions of diverse biological importance.
