[A method of multivariate analysis of data in the study of the effects of space flight factors on the rat brain neuron structure]

The usage of some methods of multivariate analysis for neuro-morphological studies is discussed. The alterations of dendritic trees of pyramidal neurons of layer III of visual cortex of the rat exposed to the influence of space flight aboard biosputnik "Cosmos-1887" were studied and the results are described to illustrate the methods power. o-technique of factor analysis was shown to be suitable for processing of the data obtained from an experiment with complex environmental conditions.
