One group of four rats was operantly conditioned in a Sidman avoidance procedure to lever press during one discriminative stimulus and to lick during another discriminative stimulus. Another group of four rats was conditioned in a similar manner in order to receive positive reinforcements. More dorsal hippocampal rhythmic slow activity (RSA) occurred during lever pressing than during operant licking. It was also found that dorsal hippocampal RSA accompanied walking and that dorsal hippocampal large irregular activity occurred during periods of immobility, during normal drinking and grooming and during the intense saliva spreading and grooming that were induced by exposure to a 40 degrees C environmental temperature. The data suggested that hippocampal RSA is related to type of response rather than to sensory, motivational, or learning processes. Furthermore, the data suggested that RSA is not related to the operant role of response or to relative vigor of response.
一组四只大鼠在西德曼回避程序中接受操作性条件反射训练，在一种辨别性刺激期间按压杠杆，在另一种辨别性刺激期间舔舐。另一组四只大鼠以类似方式进行训练以接受正强化。与操作性舔舐相比，按压杠杆期间背侧海马的节律性慢活动（RSA）更多。还发现背侧海马RSA伴随着行走，并且在不动期间、正常饮水和梳理期间以及暴露于40摄氏度环境温度引起的强烈唾液扩散和梳理期间出现背侧海马大的不规则活动。数据表明海马RSA与反应类型有关，而与感觉、动机或学习过程无关。此外，数据表明RSA与反应的操作性作用或反应的相对活力无关。
