Trace conditioning of the nictitating membrane response (NMR) was examined in rabbits with lesions of the dorsal hippocampus and fimbria-fornix. Using a white noise conditional stimulus and an electrical shock unconditional stimulus, the number and amplitude of conditional responses (CRs) was similar in hippocampus-lesioned and control subjects. At some stages of conditioning, the latencies of CRs from hippocampus-lesioned subjects were slightly shorter than those of the controls. We suggest that the hippocampus is not essential for trace conditioning but may exert a modulatory influence on the timing of the CR.
在患有背侧海马体和穹窿-海马伞损伤的兔子中，对瞬膜反应（NMR）的痕迹条件反射进行了研究。使用白噪声条件刺激和电击非条件刺激，海马体损伤组和对照组的条件反应（CRs）的数量和幅度相似。在条件反射的某些阶段，海马体损伤组的CRs潜伏期比对照组略短。我们认为，海马体对于痕迹条件反射并非必不可少，但可能对CR的时间安排施加调节性影响。
