Principal possibilities and limits of using the pharmacological approach for control of memory in studies of neurophysiological and neurochemical mechanisms of learning and memory in humans and animals are reviewed as well as its place in experimental and clinical therapy of memory disorders. Using an unspecific connector aethimizol as a pharmacological probe aided to assess changes accompanying the formation and consolidation of memory traces. The significance of fast and slow bioelectrical brain activity in the memory processing, the role of enzymes involved in transcription and template chromatine activity of the neurons under the effect of drugs on memory and learning, the correlation between time-depending learning and the pattern of RNA synthesis in brain cells, as well as possibilities and pathways of utilization of drugs in the correction of the long-term memory matrix formed by a stable pathological state of the brain, are discussed.
