The effects of low-level hippocampal stimulation on the development of latent inhibition were investigated employing classical conditioning of the nictitating membrane response of rabbits. Four groups were given either (a) no preexposure of the to-be-CS, (b) preexposure, (c) preexposure overlapped by hippocampal stimulation or (d) preexposure overlapped by cortical stimulation, followed by 300 conditioning trials for each group. After conditioning, the hippocampal group was divided into two groups designated HS-1 and HS-2 by means of a post-hoc test for stimulation effects. Conditioning was found to be retarded in all three preexposed groups, with significantly greater retardation (augmentation of latent inhibition) in Group HS-2. The results support a general conception that the hippocampal stimulation produced its effects through the modulation of sensory input.
采用兔瞬膜反应经典条件反射，研究了海马低水平刺激对潜伏抑制发展的影响。四组分别接受：（a）对即将成为条件刺激物（CS）的刺激无预暴露；（b）预暴露；（c）预暴露同时进行海马刺激；或（d）预暴露同时进行皮层刺激，随后每组进行300次条件反射试验。条件反射后，通过刺激效应的事后检验，将海马组分为两组，分别命名为HS-1和HS-2。在所有三个预暴露组中，条件反射均受到延迟，HS-2组的延迟明显更大（潜伏抑制增强）。结果支持了一个普遍观点，即海马刺激通过调节感觉输入产生其效应。
