Offense, defense, and predation, three kinds of aggressive behavior, are differentially affected by lesions of the ventromedial tegmentum of the brainstem of the rat. The lesions abolish offense while leaving defense and predation undisturbed. The offense behavior against another strange male, including bite-and-kick attack, offensive sideways posture, and offensive upright posture, was totally abolished, while the rats showed intact motor patterns of defensive upright posture, chasing, and killing bite in the tests for defense and predation. It is argued that these results support a motivational systems analysis of mammalian aggressive behavior. According to such an analysis, offense, defense, and predation are controlled by discrete motivational mechanisms located in different brainstem regions.
攻击、防御和捕食是三种攻击性行为，大鼠脑干腹内侧被盖区的损伤对它们的影响各不相同。这些损伤会消除攻击行为，而防御和捕食行为则不受影响。针对另一只陌生雄性大鼠的攻击行为，包括咬踢攻击、攻击性侧姿和攻击性直立姿势，完全消失了，而在防御和捕食测试中，大鼠表现出完整的防御直立姿势、追逐和致命撕咬的运动模式。有人认为，这些结果支持对哺乳动物攻击行为的动机系统分析。根据这种分析，攻击、防御和捕食由位于不同脑干区域的离散动机机制控制。
