Mesencephalic innervation of the turtle retina by a single serotonin-containing neuron.
Co-localization of retrograde transported Nuclear yellow and serotonin immunoreactivity revealed the existence of a central serotonergic projection to the retina in the turtle Pseudemys scripta elegans. This serotonergic retinopetal system consists of only one fiber originating in the contralateral caudal mesencephalon. In the retina, the fiber arborizes exclusively in the temporal hemisphere, covering about one third of the total retinal surface. Interestingly this projecting area lies in the part of the retina, to which binocular perception can be attributed.
