Comparative analysis of functional characteristics of connection between the fields CA3 and CA1 (Schaffer's collaterals) was performed in experiments in vivo (unanaesthetized rabbits) and in vitro (hippocampal slices of guinea-pigs) with extracellular recording of the unitary activity in the field CA1. Weakness of postexcitatory inhibition, absence of responses of the form of suppression of spontaneous activity, higher effectiveness of low-frequency stimulation of Schaffer's collaterals were observed in experiments in vitro. Posttetanic effects were more frequently observed and lasted longer in vitro than in vivo. The dominating effect in vivo was posttetanic depression and in vitro--posttetanic potentiation. The possible reasons for these differences are discussed.
在体内实验（未麻醉的兔子）和体外实验（豚鼠海马切片）中，通过细胞外记录CA1区的单位活动，对CA3区和CA1区之间连接（谢弗侧支）的功能特性进行了比较分析。在体外实验中观察到兴奋性后抑制减弱、缺乏自发活动抑制形式的反应、低频刺激谢弗侧支的效率更高。与体内实验相比，体外实验中强直后效应更频繁出现且持续时间更长。体内的主要效应是强直后抑制，而体外是强直后增强。讨论了这些差异的可能原因。
