Abstract
Effects of dopaminergic drugs (L-dopa plus benserazide, or nomifensine) on human visual function have been tested in healthy volunteers by measuring the psychophysical contrast sensitivity for sinusoidal gratings of various spatial frequencies. After drug administration the contrast sensitivity improved in all subjects over a limited range of medium to high spatial frequencies.
摘要
通过测量健康志愿者对各种空间频率正弦光栅的心理物理学对比敏感度，已对多巴胺能药物（左旋多巴加苄丝肼，或诺米芬辛）对人类视觉功能的影响进行了测试。给药后，所有受试者在中高空间频率的有限范围内对比敏感度均有所提高。
