2分钟的神经科学:膜势和动作潜力

在这两个视频中,我讨论膜电位行动潜力。膜电位是指内外和外部之间的电荷差异神经元,这是由于不平等的分布而产生的离子在细胞的两侧。期限行动潜力指在神经元内发生的电信号。这种电信令引导了释放神经递质,因此对神经元之间发生的化学通信是重要的。因此,了解动作潜力对于了解神经元如何沟通是重要的。

In this video, I discuss the action potential. The term \"action potential\" refers to the electrical signaling that occurs within neurons. This electrical signaling is an essential part of the chemical communication that occurs between neurons, and thus understanding the action potential is important to understanding how neurons communicate.","providerUrl":"http://www.youtube.com/"}" data-block-type="22" id="block-yui_3_17_2_1_1406394191908_57338">
