Behavioral changes in male rats exposed to repeated aggression
Research conducted on animal models has obtained information about the behavioral, hormonal, autonomic, neurochemical and immunological response in animals that are exposed to acute aggression by another conspecific animal. Research has also provided information about the pattern of adaptation that occurs when animals are repeatedly exposed to the experience of being attacked and defeated (for a review see1)
Effect of anosmia on the behavior of standard non-aggressive male mice opponents during agonistic encounters
This study assessed whether the differences observed in a previous experiment [Martinez M, Salvador A, Simon VM (1994): Aggressive Behavior 20:441–451] in the behavior of isolated male mice over several agonistic encounters in which they confronted either an “anosmic” or an “intact” non-aggressive “standard opponent” were due to the differences in the behavior of the opponents themselves. Ethologically-inspired analysis was used to assess the behavior of the opponents during the first agonistic encounter. Anosmic opponents spent less time in social investigation and defense and more time in immobility than intact ones. These results suggest that the differences in the behavior of the oppone…
