Flight behavior, startle reactions, and defensiveness to nonpainful stimuli were examined before and after medial amygdaloid lesions in wild Rattus norvegicus and R. rattus. Lesions which included bilateral damage to the medial nucleus strongly reduced defensiveness but had no effect on flight behavior. In contrast, damage to nearby medial structures, which spared the medial nucleus, had no effect on defensiveness but reduced flight behavior. All lesions produced a transient decrease in activity but had no effect on startle reactions. The results suggest a differential organization of flight and defense behavior within the medial amygdala.
在野生褐家鼠和黑家鼠中，研究人员对内杏仁核损伤前后的逃避行为、惊吓反应以及对非伤害性刺激的防御性进行了检查。包括内侧核双侧损伤的损伤显著降低了防御性，但对逃避行为没有影响。相比之下，对内侧核未造成损伤的附近内侧结构的损伤，对防御性没有影响，但降低了逃避行为。所有损伤都导致活动暂时减少，但对惊吓反应没有影响。结果表明内杏仁核内逃避和防御行为的组织存在差异。
