Histochemical localization of acetylcholinesterase in the glycogen body (sinus rhomboidalis) of common brown dove, Streptopelia senegalensis and house sparrow, Passer domesticus.

Acetylcholinesterase (AChE) activity was studied in the glycogen bodies of the spinal cords of 2 birds namely Streptopelia senegalensis and Passer domesticus. A possible functional significance of AChE in the light of relative enzymatic localization especially in Hoffmann-Kolliker nuclei (motor cell groups), substantia gelatinosa and other regions of gray matter of 2 avian glycogen bodies has been discussed.
