Traditionally,subthreshold potentials occurring in the soma and the dendrites are thought to be too far away from the axonal terminals to influence neurotransmitter release.However,we have demonstrated that fluctuations of membrane potentials in the soma result from the arrival of synaptic inputs during recurrent network activities could propagate along the axon with a long length constant and modulate the amplitude of spike-triggered postsynaptic potential (PSP).This suggests that the communication between cortical neurons is a mixture of digital coding (all-or-none action potentials) and analog coding (modulation of PSP by membrane potential).

我们之前的研究发现,多种刺激(如高钾溶液,谷氨酸以及电刺激)均可引起大鼠蓝斑神经元的胞体树突去甲肾上腺素分泌(somatodendritic noradrenaline secretion).Orexin是近年来发现的一类与睡眠-觉醒调节密切相关的神经肽.已知orexin可促进蓝斑神经元的纤维末梢在海马或是皮层释放去甲肾上腺素,然后是否也可参与调节胞体树突分泌并不清楚.在本实验中,我们利用微碳纤安

脑低氧预适应是脑抗缺血/缺氧的一种内源性保护现象。哺乳动物的海马脑区对缺氧/缺血极为敏感,而且海马脑区是研究学习记忆及神经可塑性等功能机制的常用模型。突触传递效率的长时程增强(long-term potentiation,LTP)是突触部位传递效能增强的一种表现形式。本研究应用脑片细胞外微电极记录技术,通过观察整体动物急性重复低氧预处理后海马脑片CA1区诱发电位及LTP诱导产生的变化,探讨低氧预适

Orexin系统与机体一系列生理功能的调控相关,其中包括学习记忆、药物成瘾、心境情绪障碍等活动的调节.前额叶皮层(prefrontal cortex,PFC)在上述这些高级神经活动的执行中发挥重要作用.谷氨酸是PFC中最重要神经递质之一,其介导的兴奋性突触传递与PFC的功能密切相关.我室前期通过观察PFC锥体神经元电活动情况,初步发现在PFC锥体神经元orexin-A与谷氨酸之间存在协同效应,但具
