这项协议描述了典型的材料和程序步骤的外科实现永久附加费的设置, 以及随后的刺激警报啮齿动物。在准备一项啮齿动物试验的过程中, 几个方法学方面 (安全和耐受性工商业污水附加费, 结果参数) 以及概念方面 (与人类状况的可比性, 对特定大脑刺激的预期效果区域) 需要加以考虑。从方法论的角度来看, 颅内的手术设置与植入的胸部计数器电极是有利的纵向研究, 因为它允许应用在警报, 自由移...

经颅的电流对大脑的管理已被用于研究大脑功能和修改行为。最近, 应用直接电流, 或较少频繁交流电流 (可和 tRNS), 通过使用两个或更多的电极 (阳极 (s) 和阴极 (s), 非通过完整的头骨, 获得了科学和临床的兴趣。特别是, tDCS 已被用于33200多个疗程的健康主题和精神病患者和神经精神疾病, 并已成为一个安全和方便, cost-effective 床边应用, 有可能的治疗潜力以及长期行为效果1。这清楚地产生了对机械研究, 包括安全方面的需求和科学兴趣的增加。本文着重介绍最常用的刺激形式, tDCS。
跨物种, tDCS 调节皮质兴奋性和突触可塑性。兴奋性的变化已报告为极性依赖性改变自发性神经元的射击率在大鼠和猫2,3,4, 或作为电机诱发电位的变化, 在人类和小鼠 (两个在阳极以后增加了并且减少了阴极 tDCS: 人5,6;鼠标7)。阳极 DCS 增加了运动皮层或海马突触的突触效果在体外刺激或长期增强后的几个小时, 当共同与一个特定的弱突触输入或当给定的可塑性诱导刺激8,9,10,11,12。根据训练, 刺激对运动或认知训练成功的好处经常被显露, 只有当 tDCS 是共同与培训8,13,14,15。虽然这些先前的发现主要归因于神经元的功能, 但应该指出的是, 神经细胞细胞 (胶质) 也可能有助于 tDCS 的功能作用。例如, 在警报小鼠的阳极 tDCS 中, 星细胞内钙水平增加了16。同样, 阳极 tDCS 的电流密度低于阈值神经诱发剂量依赖性激活小胶质细胞17。然而, tDCS 神经元-胶质细胞相互作用的调节需要进一步的具体研究。
一起, 动物研究清楚地推进我们的理解 tDCS 的调节作用对兴奋性和可塑性。然而, 在人类 tDCS 研究发表的指数增长中, 有一个 "反向平移间隙" 可观察到, 与在体外和体内动物模型。此外, 在研究实验室 (从透皮到 epicranial 刺激) 的高变异性中执行了啮齿动物污水附加费模型, 报告的刺激程序往往不完全透明, 阻碍了可比性和可基础研究数据以及结果解释。
在这里, 我们详细描述了一项经颅脑部刺激设置的外科实施, 针对初级运动皮层, 它允许翻译的人 tDCS 条件, 同时尽量减少变异性, 并允许重复的刺激没有阻碍行为。给出了警报大鼠后续附加费的 step-by 步骤协议。讨论了安全应用于警戒啮齿动物的方法和概念方面。

transcranial electrical brain stimulation in alert rodents
