  • Title: [Varations between strains in the concentration of RNA in the cerebral cortex of rats differing in their capacity for learning].
    Author: Ivonin AA.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1978 Feb; 64(2):242-4. PubMed ID: 640092.
    Abstract:
    Concentration of RNA in the brain cortex was investigated in two strains the rats Wistar and Krushinsky--Molodkina. It is found that K--M rats, which have higher speed of learning possess higher concentration RNA in the cortex brain than rats of Wistar strain. Conditional reflectory training of rats induced increase of RNA concentration in the brain cortex experimental rats when it is compared with control groups of rats. It is suggested that there is not only an ontogenetic, but also a genetic correlation between the level of RNA the brain cortex and a capability the rats to the learning.
