Abstract:
:The distribution and synaptic connections of the indoleamine-accumulating neurons in the retinae of the goldfish and carp were studied by means of fluorescence and electron microscopy. The indoleamine-accumulating neurons were visualized after intravitreal injection and uptake of the indoleamine 5,6-dihydroxytryptamine. This labeling procedure produced a characteristic yellow fluorescence of the indoleamine-accumulating neurons and also characteristic ultrastructural changes in these cells. To avoid interference from the dopaminergic neurons of the retina, their processes were either removed by prior treatment with 5-hydroxydopamine or prevented from taking up 5,6-dihydroxytryptamine by the simultaneous injection of the catecholamine alpha-methyl-noradrenaline. Fluorescence-microscopic studies confirmed earlier reports that the indoleamine-accumulating perikarya and processes are distributed similar to those of amacrine cells. The indoleamine-accumulating processes ramify in three bands in the inner plexiform layer, the outermost one being the densest. Electron-microscopic investigations showed the indoleamine-accumulating neurons to have synapses of the conventional type, similar to amacrine cells. Their main synaptic contacts are with other amacrine cells, but synapses with bipolar cell terminals are also present. Both the distribution of the indoleamine-accumulating processes and their synaptic arrangement in the cyprinid retina differ from those found in mammalian retinae investigated previously.
