Lesions in ventromedial part of amygdala impaired neither alimentary instrumental reflexes nor food intake, but impaired predatory behavior. Lesions localized in the more dorsal and lateral part of the amygdala produced disorders in instrumental performance and food intake without changes in predatory attack. Both kind of lesions did not impair neurological reflexes, therefore the abolishment of predatory attack after ventromedial amygdala damage was not caused by sensory-motor disturbances. It is concluded that predatory behavior is based on specific mechanisms separate from both alimentary and instrumental ones.
杏仁核腹内侧部分的损伤既不损害进食性工具反射，也不影响食物摄入，但会损害捕食行为。位于杏仁核更靠背侧和外侧部分的损伤会导致工具性操作和食物摄入出现障碍，而捕食攻击无变化。这两种损伤均不损害神经反射，因此杏仁核腹内侧损伤后捕食攻击的消失并非由感觉运动障碍所致。结论是，捕食行为基于与进食和工具性行为不同的特定机制。
