摘要

通过测量不同空间频率正弦光栅的心理物理对比灵敏度,在健康志愿者中测试了多巴胺能药物(左旋多巴加苯塞拉肼或诺米芬)对人类视觉功能的影响。在给药后,所有受试者在有限的中高空间频率范围内的对比敏感度都有所提高。

Dopaminergic drugs improve human visual contrast sensitivity.

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.
