虽然培养神经元的“夹心层”的方法已在别处良好描述2， 如图11所示 ，在整个协议的几个步骤是相当困难的独自描述的文字，这可能会导致沮丧谁希望采纳调查。 该方法可分为三大工作流程：神经胶质培养，盖玻片制备和神经元培养物和维护。这三个准备的是高品质的神经元培养和几个重要的关键因素，必须牢记。电镀神经元前?...

大脑分为神经元的复杂网络。单个神经元到网络活动和脑功能的贡献可以通过它们的分子组成和它们的生理特性的扰动的选择性改变进行研究。单个神经元的遗传和化学处理是在培养的神经元比完整的脑组织受到后者的细胞的异质性和复杂性可以说是容易，无牵无挂。在培养神经细胞发展良好定义的轴突和树突乔木和彼此形成广泛的突触连接。 而来自成年动物或来自神经系统的其他区域神经元培养物是可能的，胚胎海马培养物经常由于优选为所定义的锥体细胞群体和相对低的密度胶质1,2。在培养低密度生长的海马神经元是特别AMEnable到亚细胞定位，蛋白质运输，神经元极性和突触发育的研究。在培养神经细胞也在突触可塑性3，4，5，6研究分子过程被广泛使用。从与不出生后存活的全球基因缺失的小鼠神经元文化的准备工作已经在研究某些基因7的细胞和突触的角色特别有用。 由于在脑，海马神经元依赖于从神经胶质细胞营养支持。这他们的文化复杂化，并导致由这种支持提供几种不同的方法的发展。一种常用的方法包括直接电镀到神经元的神经胶质细胞8，或允许从所获取的HIPP污染物神经胶质细胞的单层ocampal组织增殖并形成神经元9下方的单层。虽然这种方法已经发现了一些成功，得到的神经元培养物中的杂质是不利的成像实验。神经元培养物的另一种常用的方法是将离开时的胶质饲养层完全，而是提供在限定的生长培养基10的形式营养支持。 在这里，我们描述了“三明治”或神经元培养2,11的“银行家”的方法。此方法涉及镀覆在玻璃盖玻片上，然后将其悬浮在由石蜡珠分离的神经胶质细胞的单层的海马神经元。这有利于神经细胞的同质群体的长期培养，而不会污染的神经胶质细胞，同时允许从底层的神经胶质单层营养支持。当神经元是足够的年龄和成熟程度的，神经元盖玻片可翻转时的胶质菜和在成像或功能测定法中使用。
