前间隔损伤的大鼠表现出防御行为持续增强的模式，通常由威胁同种动物引起，但攻击或一般反应性没有增强。该组的进一步划分表明，对间隔区前部和腹侧部位（先前与间隔综合征有关的部位）的损伤对这些行为产生最大影响。当杏仁核损伤与间隔损伤相结合时，这种增强的防御反应几乎完全消除。间隔综合征可能代表对同种威胁刺激的过度防御，而不是攻击性或一般反应性增加。杏仁核机制也可能参与同种防御行为的调节。
Rats with anterior septal lesions showed a pattern of consistent enhancement of defensive behaviors normally elicited by threatening conspecifics, with no enhancement of attack or general reactivity. Further division of this group indicated that damage to sites anterior and ventral to the septal area, sites previously implicated in the septal syndrome, produces maximal effect on these behaviors. When amygdala lesions are combined with septal damage this enhanced defensive responding is almost completely eliminated. The septal syndrome probably represents hyperdefensiveness to conspecific threat stimuli rather than aggression or increased general reactivity. Amygdaloid mechanisms may also be involved in the regulation of conspecific defensive behaviors.
