The aim of this work is automation of neurophysiological experiments, namely, intelligent video monitoring of the behaviour of laboratory rats during the social recognition cognitive test on the working memory. The test is conducted in the box with a sawdust background, simultaneously with EEG recording. Automatic video processing supplies objectivity of the interpretation of the results of the testing and provides new possibilities for the standardizing of the neurophysiological experiments. In the paper, methods and means for the logical description and analysis of the behaviour of experimental animals are considered. Recommendations for improving the experimental technique of the social recognition test are elaborated on the base of the results of the experiments with the automatical video processing.
