Summary
Disturbance of production of acetylcholine in the organism following removal of the pancreas brings about increased speed of accommodation and of development of parabiosis in the sciatic nerve in frog.
Administration of small doses of acetylcholine to operated and normal frogs results in decreased speed of accommodation and of development of parabiosis.
The correlated changes of accommodation and parabiosis demonstrate that these processes are related and allow us to consider the process of accommodation as a manifestation of the development of local excitation due to the effect of stimulation.
