Are there dopaminergic ganglion cells in the mammalian retina?
New improvements of the tyrosine hydroxylase immunocytochemical labelling in wholemounts allowed us to visualize tyrosine hydroxylase-immunoreactive fibres in the nerve fibre layer of the mouse, rat and macaque monkey retinas. These fibres could not be related to labelled somata in the retina. Their possible origin from ganglion cells or brain nuclei is discussed.
