Abstract
The release of [3H]dopamine from the cat's retina was determined by measuring the level of radioactivity in a series of vials in which the retina was incubated. At light ON; there was a sustained decrease and at light OFF there was an enhanced release of dopamine. The results also demonstrate that dopamine is released continuously in the dark.
