/></p></p><p><br  /><span></span></p><p><span>该技术的开发者之一亚瑟·洛维里在一份声明中说：“皮层视觉假体旨在通过向视觉皮层(大脑中接收、整合和处理视觉信息的区域)传递电刺激来恢复那些失去视觉的人的视觉感知。”。“我们的设计通过多达172个光点的组合创造了一种视觉模式，为个人提供了在室内和室外环境中导航的信息，并识别他们周围的人和物体的存在。”&nbsp;</span></p><p><br  /></p><p><span>Gennaris系统中的技术已经在绵羊身上进行了试验，并在今年早些时候的《神经工程杂志》上发表了非常积极的结果。在这项研究中，对动物进行了2700多个小时的视觉刺激，没有任何明显的副作用。</span></p><p><br  /></p><span>该研究的主要作者杰弗里·罗森菲尔德补充说:“研究结果表明，通过无线阵列的长期刺激可以实现，而不会引起广泛的组织损伤，也不会因刺激而导致明显的行为问题或癫痫发作。”</span></section><section><p><br  /></p><p><a
