Electrical activity of hippocampus was investigated in cats in the delayed response situation by comparing spectral analysis and integration of electrohippocampogram rhythms in different stages of delayed response performance. In addition, electrical stimulation of lateral and ventromedial hypothalamic nuclei was used to observe changes in the hippocampal theta rhythm, as well as the behavioral effect during the delayed response performance. It is concluded that changes in the hippocampal theta rhythm are related to the changes in the drive level: high drive results in increasing the theta rhythm, whereas drive reduction results in its suppression. The activating role of hypothalamus in the dynamic changes occurring in the limbic circuit and their function in solving the delayed response problem are widely discussed.
通过比较延迟反应执行不同阶段海马电图节律的频谱分析和积分，研究了猫在延迟反应情况下海马的电活动。此外，采用电刺激下丘脑外侧核和腹内侧核，观察延迟反应执行过程中海马θ节律的变化以及行为效应。得出结论：海马θ节律的变化与驱动水平的变化有关，高驱动导致θ节律增加，而驱动降低则导致其抑制。广泛讨论了下丘脑在边缘回路中发生的动态变化中的激活作用及其在解决延迟反应问题中的功能。
