[Sensory organization of the reticular formation: Specific integrative activity]

On the basis of personal investigations including 1) electrophysiological methods (EEG, averaged evoked potentials), 2) behavior methods, 3) destruction of various parts of the brain (mesencephalic reticular formation, auditory pathways) and 4) pharmacological methods, conducted in the years 1953-1974 the author put forward a concept of sensory organization of reticular formation postulating existence of special systems in the reticular formation differing in their relative physiological and chemical specificity. This relative specificity is, in this concept, the ability of the so-called non-specific neurons in the reticular formation to be included under certain experimental conditions into specific functional systems. The author suggests the term "paraspecific systems" for designating these relatively specific systems. It seems that these systems determine the integrative role of reticular formation in the process of learning. In contrast to this important role the reticular formation is without any greater importance for the process of memory storage. The dynamic and relatively specific functional organization of reticular formation provides potential possibilities of its utilization in the processes of reeducation or rehabilitation in central nervous system damage and in pharmacological treatment of psychic disturbances.
