title: [RNA synthesis in the brains of rats with changes in the function of their central nervous systems].
abstract: A method of electrophoresis in polyacrylamide gel was applied to the study of the RNA synthesis in the phenol nuclei and the cytoplasm of the cells of the higher portions of the brain in rats under normal conditions, during training of these animals in the motor-defence habit in a complicated labyrinth, and in active control (irregular presentation of motor-defence stimuli). Behaviouristic stimulation and an irregular presentation to the animals of the same stimuli as in the elaboration of habits, but not leading to their formation, activated the RNA synthesis in the phenol nuclei with sedimentation characteristics of 18S, 28S and over. Thy cytoplasmic RNA displayed an increase in the labeled precursor incorporation in the 18S region.
