Abstract

A midbrain hemisection in a midpontine pretrigeminal preparation of the cat causes an asymmetry in the electroencephalogram with a marked increase in the acetylcholine content of the cortex from the synchronized hemisphere. It is suggested that the increase in acetylcholine is related to the decrease of nervous activity caused by the hemisection.
