[Effect of electroshock on intraspecific behavior of mice maintained in isolation].

By means of probabilistic-ethological analysis it was shown on isolated mice that the direct effect of primary electroshock is manifested in an inversion of the isolant's aggressive behaviour into a defensive one. Delayed (24 hours) and chronic effects of the electroshock (applied daily during a week) were manifested in a change of behaviour pattern of the isolants (appearance of the previously absent phase of investigating the partner and the environment before aggressive attack), in diminished probability of appearance of aggression and increased intraspecies sociability. All effects of the electroshock on intraspecies behaviour had rigid temporal limitations.
