[Factor analysis of rat behavior in the open-field test].
Method of major components, a variety of factor analysis, was used for evaluation of rats behaviour motivational structure in the open field test. 40 outbred rats of Wistar line (20 males and females) were examined in which 22 behaviour characteristics were studied. It was shown that a greater part (60%) of rats individual behaviour variability in the open field test was determined by the action of three major components (factors), which were defined as "investigation", "fear" and "shifted activity". Factor structure was studied of main characteristics of behaviour, recorded in the open field test. The use of factor analysis allowed to carry out animals classification on the basis of their disposition in coordinates of the obtained major components.
