Chronically implanted intraocular electrodes were used to stimulate visual cortical responses to current passage through the retina. Electrical current threshold for the light-adapted cat retina lies in the region of 30 to 100 X 10(-6) amps. for the conditions used. Dark adaptation caused a large threshold increase. Retinal excitability also decreased when electrical stimuli were delivered more often than one per 5 seconds. Effective charge-density threshold was moderately greater than reported for frogs and humans.
长期植入的眼内电极被用于刺激视觉皮层对电流通过视网膜的反应。在所用条件下，适应光的猫视网膜的电流阈值在30至100×10⁻⁶安培范围内。暗适应导致阈值大幅增加。当电刺激的发放频率高于每5秒一次时，视网膜兴奋性也会降低。有效电荷密度阈值略高于青蛙和人类的报道值。
