since indoleaminergic cells make reciprocal synaptic connections with rod bipolar cell terminals , which are depolarizing in the rabbit retina , we hypothesize that 5-ht2 receptors facilitate the synaptic transmission from the depolarizing rod bipolar cell thus facilitating on-excitation in the retinal network while 5-ht1a receptors mediate an inhibitory process .
