Behavioral and biochemical characteristics of rats preferring ethanol or water

Considering that learning and memory processes are largely determined by the intensity of RNA synthesis in specific brain structure, the authors study the relationship between learning ability of rats preferring ethanol or water and the level of RNA-synthesizing activity of brain cell nuclei. RNA-synthesizing activity of cell nuclei from cortical gray matter of the animals was determined one month after selection by measuring incorporation of deuterium-uridine triphosphate. The numerical results were subjected to statistical analysis by Student's test at P 0.05. It is shown that the altered behavior of animals preferring ethanol is evidently based on disturbed interaction between mediator and genetic structures of brain cells
