Neuronal responses were recorded in the dorsal part of the rabbit hippocampus to a, aperiodical (45 units) and b, periodical (25 units) presentations of combinations of a sound and a DC pulse (anode, 0,1-2,0 na) acting through the recording microelectrode. In the group (a) identified conditioned responses to a former indifferent acoustic stimulus were elaborated in 22% of the neurones. More than a half of them produced differentiation and extinction. Differences were revealed between conditioned reactions and responses in pseudoconditioning tests. In the group (b) 30% of units elaborated a conditioned reaction to time. Activation type reactions were predominant. They appeared when the stimuli were omitted, and sometimes they emerged in 12 or more successive omissions.
在兔海马体背侧记录神经元反应，刺激为通过记录微电极施加的声音和直流脉冲（阳极，0.1 - 2.0纳安）组合，分为a. 非周期性（45个单位）和b. 周期性（25个单位）呈现。在组（a）中，22%的神经元形成了对先前无意义听觉刺激的条件反应。其中超过一半出现了分化和消退。在伪条件测试中，条件反应和反应之间存在差异。在组（b）中，30%的单位形成了对时间的条件反应。激活型反应占主导。当刺激被省略时出现，有时在连续12次或更多次省略时出现。
