[A systems analysis of the defensive behavior of Wistar rats during bilateral active avoidance training].

Formation of the new behavioral act (active avoidance in shuttle box), its relationship with other forms of defensive behavior were studied in Wistar rats. During learning all the forms of defensive behavioral and motor activity were recorded. In result of the cluster-analysis (ISODATA) some tactics of defensive behavior were described. The results are discussed according to Anokhin's theory of the functional system.
