[Postural asymmetry in rats after unavoidable pain stimulation of different durations]

Reaction of pose asymmetry was studied in rats subjected to unavoidable pain stimulation of 5 and 20 min duration after chordotomy. Single 20-min stimulation led to the appearance in all animals of right-side pose asymmetry, if the chordotomy took place immediately after the impact. If the chordotomy took place 24 h after the stimulation, the animals were revealed both with the right- and left-side pose asymmetry, analogous to the rats after 5-min stimulation. Cerebrospinal fluid of the animals subjected to the influence of various duration elicited in recipients pose asymmetry at the same side as in the donor. The role is shown of individual characteristics in the appearance of the definite side of the pose asymmetry.
