Discrete distributions of putative cholinergic and somatostatinergic amacrine cell dendrites in chicken retina.
The distributions of putative cholinergic and somatostatinergic amacrine cells of the chicken retina were compared. Acetylcholinesterase-positive amacrine cell bodies were concentrated at the border between the inner nuclear and plexiform layers. Similar amacrine cell bodies were detected in a displaced position in the ganglion cell layer. Both populations had dendrites joining the 4 bands of acetylcholinesterase activity in the inner plexiform layer. The cell bodies of somatostatin-immunoreactive amacrine cells were distinct from the intensely acetylcholinesterase-positive cell bodies. The immunoreactive terminal bands did not overlap the acetylcholinesterase-positive bands, except in the inner parts of the inner plexiform layer.
