摘要

视觉皮层的电刺激使受试者在他们的视野中看到光点(幻视)。作者已经开发了穿透电极阵列，可以形成以视觉皮层电刺激为中心的视觉假体的基础。这些阵列由惰性材料构成，并已植入猫体内以测试阵列的可插入性和生物相容性。还进行了确定电极线插入力的测试。初步的急性组织学结果显示，由于植入物造成的皮质损伤很小。

Noble metal penetrating cortical stimulating electrode array: preliminary results

Electrical stimulation of the visual cortex causes subjects to see spots of light (phosphenes) in their visual fields. The authors have developed arrays of penetrating electrodes which can form the basis of a visual prosthesis centred around electrical stimulation of the visual cortex. These arrays have been constructed of inert materials, and have been implanted into cats to test array insertability and biocompatibility. Tests to determine electrode wire insertion force have also been performed. Preliminary acute histological results have shown little cortical damage due to the implants.<>
