海马锥体神经元在经典条件反射的兔眼睑反应中表现出快速的试验内放电频率增加。有人提出,海马长时程增强(LTP)的细胞机制也可能介导这种学习依赖性的神经元活动的增加。大鼠海马脑片LTP的诱导导致增强区[3H]谷氨酸结合位点数量的增加。本研究探讨了[3H]谷氨酸结合海马突触膜后,眼睑条件反射在兔的动力学。我们报告说,[3 H]谷氨酸结合在兔海马各层中的区域分布与树枝状定位是一致的。结合的药理学和离子性质表明,它与兴奋性氨基酸受体有关。眼睑调节后,海马[3H]谷氨酸结合位点的最大数量增加,在动物接受配对介绍的音调条件刺激和角膜喷气非条件刺激相对于幼稚或未配对的对照动物。这些结果加强了一个假设,LTP样机制的基础上增加海马放电频率在兔眼睑空调。
Hippocampal pyramidal neurons exhibit a rapid within-trial increase in firing frequency during classical conditioning of the rabbit eyelid response. It has been proposed that the cellular mechanisms responsible for hippocampal long-term potentiation (LTP) may also mediate this learning-dependent increase in neuronal activity. The induction of LTP in rat hippocampal slices results in an increase in the number of [3H]glutamate-binding sites in the potentiated region. The present study investigates the kinetics of [3H]glutamate binding to hippocampal synaptic membranes after eyelid conditioning in the rabbit. We report that the regional distribution of [3H]glutamate binding across the layers of rabbit hippocampus is compatible with a dendritic localization. The pharmacological and ionic properties of the binding suggest that it is associated with an excitatory amino acid receptor. After eyelid conditioning, the maximal number of hippocampal [3H]glutamate-binding sites is increased in animals receiving paired presentations of the tone conditioned stimulus and corneal air-puff unconditioned stimulus relative to that found in naive or unpaired control animals. These results strengthen the hypothesis that an LTP-like mechanism underlies the increase in hippocampal firing frequency during rabbit eyelid conditioning.
