a novel approach for documenting phosphenes induced by transcranial magnetic stimulation

人类视觉皮层的刺激产生的光的短暂的知觉，称为光幻视。幻视侵入枕叶皮层电刺激诱导，而且是由非侵入性的经颅磁刺激（TMS）<sup&gt; 1</sup&gt;相同的皮层区域。一个幻视是诱发的强度（幻视阈值）是视觉皮层的兴奋性的行之有效的措施，是用来研究皮质皮层的相互作用，功能组织<sup&gt; 2</sup&gt;，易患病理<sup&gt; 3,4</sup&gt;和视觉处理<sup&gt; 5-7</sup&gt;。幻视通常定义三个特点：他们是在视觉上hemifield对侧刺激观察，它们是诱发主体的眼睛是开启或关闭时，和他们凝视的方向与空间位置的变化<sup&gt; 2</sup&gt;。各种各样的方法已被用于文件幻视，但缺乏一种标准化的方法。我们展示了可靠的程序，以取得幻视的阈值，并引入新型幻视的文件和分析系统。我们开发的激光跟踪和绘图系统（LTaP），成本低，很容易建立和运作系统，记录的位置和大小的实时感知幻视。 LTaP系统，提供一个稳定和可定制的的量化和分析幻视的环境。
