Indoleamine-accumulating neurons in the retina of rabbit, cat and goldfish

  • 39 Accesses

  • 107 Citations


Special neurons accumulating indoleamines have been detected in the retina of rabbit, cat and goldfish. They have their perikarya in the inner-most cell row of the inner nuclear layer, among the amacrine cells, and send their processes to various parts of the inner plexiform layer. The distribution of the processes is different in the different animals investigated. The neurons do not correspond to the previously known dopaminergic retinal neurons, which have a different distribution of their terminals and which can be demonstrated with a specially developed technique, simultaneously with the indoleamine-accumulating neurons.
