| Research Abstract |
Histamine and histamine H1 receptor exist in the gerbil retina, and that H2 and H3 receptors were expressed on developing gerbil ganglion cells.
In human rod photoreceptors, dopamine reduced h current (Ih) through a D2 receptor, and inhibited the gradual decay in the voltage response via a D2 receptor, indicating that dopamine slows the recovery phase of responses to light stimuli by inhibiting Ih in human rods.
