title: [A factor analysis of behavioral organization in mice].
abstract: Laboratory mice with Robertsonian translocation Rb(8,17)1Iem, mice of CBA substrain with the same translocation as well as CBA normal karyotype mice were investigated in several behavioural tests, their results being analysed by means of factor analysis. The genetic differences were revealed in the patterns of factor loadings, in particular in factors "feeding behaviour structure" and "weight loss". The behaviour of mice during logic problem solving (the ability to extrapolate the direction of food stimulus movement was tested) proved to be genotype-dependent in respect to connections with exploratory behaviour indices. Tendencies towards stereotypic or variable (plastic) behaviour patterns were revealed in CBA mice and mice with Rb(8,17)1Iem mice respectively.
