1D图案是可用于多种应用的重要工具。例如，我们已经使用一维图案用于从神经元培养29创建逻辑门以及最近测量大鼠海马神经元5的时值和Rheobase，和唐氏综合征的海马神经元电活动的信号传播速度的下降的减速比野生型（WT）海马神经元27。一维图案的建议的方案是稳健的，这是容易形成任何所需的图案。我们建议观察1D培养前测量，以了解?...

神经元和外部电场之间的相互作用具有根本性的影响以及实际的。虽然人们自从沃尔的倍外部施加的电场可以激发组织已知的，负责神经细胞中生产的所得动作电位的机制最近才开始被揭开1，2，3，4。这包括关于查找导致膜电位的去极化，膜性质和离子通道的作用，甚至该区域响应该电场2,5神经元的机制问题的答案。治疗神经刺激6，7，8，9， <sup10类方法特别依赖于这些信息，这对于针对受影响的地区和了解治疗结果来说可能至关重要。这种理解也可以帮助制定治疗方案和刺激大脑不同区域的新方法。 测量体内大脑内的相互作用为这一理解提供了重要的组成部分，但受到颅骨内测量不精确和低可控性的阻碍。相比之下，文化中的测量可以很容易地以高精度，优异的信噪比和高重现性和控制的高精度执行。使用文化可以阐明集体网络行为的各种神经元属性11,12,13,14 ， </sup&gt; 15，16 。类似地，期望这种良好控制的系统在阐明其他刺激方法的作用机制方面是非常有效的，例如在光激活神经元17,18,19中的光学刺激期间如何通道开放负责产生动作电位。 这里的重点是描述可以通过外部电场有效地激发神经元的工具的开发和理解。在本文中，我们描述了二维和一维图案海马培养物的制备，使用浴电极直接施加的电场的不同构型和取向的刺激，最后通过一个刺激二维和图案化的一维培养物时变磁场，其引起电场5，20，21 。

external excitation of neurons using electric and magnetic fields in one- and two-dimensional cultures

当它的膜电位超过某个阈值的神经元就会触发动作电位。在大脑中的典型的活性，这发生如化学投入到它的突触的结果。然而，神经细胞也可以通过强加的电场激发。尤其是，最近的临床应用程序激活由外部产生电场的神经元。因此，感兴趣的研究神经元如何响应外场是什么原因导致的动作电位。幸运的是，外部电场的精确和受控应用是可能的被切下，解离和在培养物中生长的神经元的胚胎细胞。这使得在一个高度可重复的系统，这些问题的调查。 在本文中的一些用于外部电场对神经元培养物控制的应用程序的技术进行了综述。这些网络可以是一维的，在LINEA 即图案化ř形式或允许在基板的整个平面成长，因此二维的。此外，激发可通过电场直接应用通过浸入流体（浴电极）或通过使用磁脉冲的远程创建诱导电场的电极产生。

<html>提出的协议允许神经元培养物的容易构图。当它与我们为刺激开发了几种方法相结合，它能够使一些内在的神经元属性，如时值和Rheobase 5的测量，比较健康和疾病的神经元27的特性，找到最佳的方法来刺激文化之间的函数关系它们的结构和更多的新方法。一些例子，在未来的数字呈现。 <p class="jove_content" fo:keep-together.within-page="1"...
