Dopamine and light: dissecting effects on mood and motivational states in women with subsyndromal seasonal affective disorder

摘要

BackgroundDespite evidence that bright light can improve mood, the neurobiology remains poorly understood. Some evidence implicates the catecholamines. In the present study, we measured the effects of transiently decreasing dopamine (DA) synthesis on mood and motivational states in healthy women with mild seasonal mood changes who were tested in either bright or dim light.
