On the distributive patterns of ATPase activity and its functional significance in retinae of certain birds.
The present study incorporates the details of distribution of adenosine triphosphatase amongst the various constituents of retinae of Passer, Psittacula, Streptopelia and Athene. The outer segments in all the cases are intensely positive for the enzyme. This is the part where the light strikes first and initiates the visual processes. The nuclear layers are also positive for the enzyme activity. It is interesting to note that inner plexiform layers show clear-out demarcations of various sub-synaptic layers in all the birds except Psittacula. The ganglion cells and optic nerve fibres are also positive for the enzyme.
