Behavioral reactions (submissive postures, escape, immobility, activity, locomotion) in C57BL/6 and DBA/2 test mice were recorded during single (50 bites) or three repeated (3 X 50 bites, separated by 24 hr) aggressive confrontations, as well as during a nonaggressive confrontation 24 hr after the last aggressive confrontation with opponents of the opposite strain. Nociception (hot plate response latency) was measured 1 min after aggressive or nonaggressive confrontations. During repeated aggressive confrontation, DBA mice reacted with a stable pattern of escape and analgesia, whereas C57 mice failed to develop an analgesic response and changed their behavioral defense strategy during repeated aggressive confrontations (decrease of escape, increase of defensive upright). The conditioned display of submission and of escape behavior during nonaggressive confrontation did not change as a function of earlier repeated aggressive confrontations in DBA mice, while C57 mice showed a significant increase of defensive upright postures and immobility. Conditioned analgesia was not observed after nonaggressive confrontations. The results point toward a dissociation between attack-elicited behavior and antinociception and suggest that encounter-induced analgesia may influence the processing of aversive experience.
