讨论了大鼠乳腺系统损伤对空间记忆和觉醒的影响。内侧乳核或乳盖束的破坏会在延迟交替任务中产生损伤，并大大增加开放区域的活动。乳丘束的损伤会产生不同的影响，因为空间交替缺陷伴随着普遍的嗜睡和无反应。乳腺系统可能在本体感觉信息的短期存储中起着至关重要的作用，这些信息是连续执行迷宫选择所必需的。它似乎也在动物的觉醒状态中发挥作用。
The effects of lesions of the mammillary system [in rats] on spatial memory and arousal were discussed. Destruction of the medial mammillary nucleus or the mammillotegmental tract produces impairments on a delayed alternation task and greatly increases activity in the open-field. Lesions of the mammillothalamic tract produce a differential effect in that the spatial alternation deficit is accompanied by a general lethargy and unresponsiveness. The mammillary system may play a crucial role in the short-term storage of proprioceptive information necessary for the successive execution of maze choices. It also appears to play a role in the arousal state of the animal.
