[Probabilities and ethologic analysis of the zoosocial behavior of grouped and isolated mice]. / Veroiatnostnyi i étologicheskii analiz zoosotsial'nogo povedeniia sgruppirovannykh i izolirovannykh myshei.

The effectiveness of probabilistic and ethological approaches to the analysis of normal and pathological animal behaviour is shown. The probabilistic analysis of the frequency, duration and sequence of a large variety of behavioural acts and postures permits to single out the most significant events and diad transitions in the interaction between two animals (previously isolated or grouped). Computer and probabilistic analysis reveals sharp differences in the structure of these acts and their interdependence in isolated and in grouped mice. It is noted that in isolation there occur fixation of the program of aggressive behaviour, a sharp narrowing of the spectrum of possible transitions from aggression to other forms of intraspecific behaviour, aggression being little controlled by intraspecific inhibitory factors which is regarded as pathology of behaviour.

[Discrete and continuous mathematical models of intraspecific behavior in the pharmacoethology of the mouse]. / Diskretnaia i nepreryvnaia matematicheskie modeli vnutrividovogo povedeniia v farmakoétologii myshei.

An algorithm and software library were compiled in order to interpret the intraspecies agonistic animal behaviour in terms of discrete or continuous mathematical model. Applied aspects of the use of mathematical models in pharmacoethology were shown on concrete examples. The ways of construction of standard prototypes, and the integrative criteria of psychotropic drugs action were developed. The possibility was shown of identification of unknown substances by comparing with standard drugs by calculating the norm of standardized matrices.
