：猫背海马神经元的自发电活动和诱发电活动显示，小脑顶核和间核的刺激对海马神经元活动的影响以双侧为主，对侧影响更明显。在对侧海马神经元中也更经常观察到来自所研究结构的传入信号的收敛。顶核刺激的影响占主导地位。记录的反应具有多突触性质。形态学实验表明，小脑传出纤维和海马神经元之间缺乏单突触连接，小脑中央核破坏导致实验性变性。讨论了从小脑到海马的信息传输的可能方式以及小脑-海马互连的功能作用。
: Spontaneous and evoked electric activity of the cat dorsal hippocampus neurons revealed the stimulation of cerebellar fastigial and interpositus nuclei to have bilateral mostly facilitating influence on hippocampal neuron activity, with more obvious contralateral effects. Convergence of afferent signals from structures under study is also more often observed in contralateral hippocampal neurons. Effects of fastigial nucleus stimulation are predominant. Recorded reactions have polysynaptic nature. Absence of monosynaptic connection between cerebellar efferent fibers and neurons of hippocampus was revealed by morphological experiments with experimental degeneration caused by destruction of cerebellar central nuclei. Possible ways for information transmission from cerebellum to hippocampus and functional role of cerebello-hippocampal interconnection are discussed.
