The activity of the retinal dopamine neurons was studied in light-adapted rats exposed to darkness for periods ranging from 10 min to 15 h. Dihydroxyphenylalanine (DOPA) accumulation, following inhibition of L-aromatic amino acid decarboxylase with NSD-1015, was used as an index of dopamine neuronal activity. After only 10 min of darkness, DOPA accumulation had decreased to levels found in rats dark-adapted for 15 h.
在光照适应的大鼠中，研究了其视网膜多巴胺神经元在暴露于黑暗中10分钟至15小时期间的活动。用NSD - 1015抑制L - 芳香族氨基酸脱羧酶后，二羟基苯丙氨酸（DOPA）的积累被用作多巴胺神经元活动的指标。仅在黑暗10分钟后，DOPA积累就已降至适应黑暗15小时的大鼠中的水平。
