Abstract
Elementary reasoning (the ability of mice to extrapolate the direction of alimentary stimulus movement) was investigated in genetically different groups of animals. Mice with Robertsonian translocation Rb(8,17)1IEM were superior in extrapolation task solving to mice with a normal karyotype, or mice with Robertsonian translocations of other types (Rb(5,19)1Wh, Rb(6,15)1ALD, Rb (9,14)6Bnr, Rb(16,17)7Bnr). Mice selected for low brain weight were superior to mice with high brain weight in extrapolation task solving in F3-F11. In F12-F14, this difference was absent. Mice with Robertsonian translocations and mice selected for brain weight are perspective models for physiological and genetic studies of elementary reasoning.
