这个实验得到国家依赖的心。在V1/V2神经元被认为是符合简单，定向运动 7,8因此，适应单向的动机刺激增加注册这项运动的神经元的兴奋性-正因为如此，他们应该首先做出反应的TMS脉冲。 V5/MT +配合物还包含了调整，以简单的平移运动神经元，因此，从本地区引起的幻视，也应适应刺激的影响。然而，V5/MT +复杂也被认为是包含不同的注册径向运动神经元9,10正因为如此，爆模式应?...

state-dependency effects on tms:  a look at motive phosphene behavior

经颅磁刺激（TMS）是一种非侵入性neurostimulatory和neuromodulatory技术，可以短暂或持久的应用本地化的磁场脉冲通过调节大脑皮层兴奋性（增加或减少），在TMS的领域 ，长期1,2 国家的依赖 ，是指初始，为刺激神经 ​​的特定目标区域的基线状况。可以推断，TMS的影响可以（并）根据这个首要的易感性和有针对性的皮层区域的反应 。3,4,5 在这个实验中，我们会研究这个国家依赖的概念，通过启发和主观动机幻视经验。幻视视觉感知的视觉皮层的电磁脉冲引发的小灯闪烁。这些小灯可以承担不同的特点，根据刺激类型的视觉皮层是。在这项研究中，我们将目标锁定为引起动机幻视通过刺激V1/V2和V5/MT +复杂的视觉区域。
