Abstract: | Intraspecies experience of domination or subordination in mice is an important factor predetermining their specific behaviour in response to painful stimuli, The significance is emphasized of ethological investigations for studying behavioural reactivity to pain and correct differentiation of responses of "defence-subordination" and "aggression-offence" types. The specificity of diazepam effect on the character of behaviour in response to pain was analysed in animals of different hierarchic rank. |
