Abstract
In the chicken retina, choline acetyltransferase-like immunoreactivity (ChAT-LI) defines
three populations of cholinergic amacrine cells and two terminal bands in the inner
plexiform layer (IPL). Acetylcholinesterase (AChE) histochemistry defines two prominent
bands within the IPL which corresponded to those containing ChAT. Other AChE-positive
bands in the IPL are not associated with cholinergic transmission sites. Cholinergic
cell bodies contain AChE, but the most intensely AChE-positive cells do not appear
to be cholinergic. AChE histochemistry may be used to define the major cholinergic
synaptic sites in the IPL, and may be a useful marker of IPL lamination.
