Concentrations of cAMP and activity of pertinent enzymes in certain brain structures of the rabbit

The concentrations of cAMP and the activity of adenyl cyclase and specific cAMP-phosphodiesterase were determined in certain structures of rabbit brain. Statistically significant differences were found in the concentrations of cAMP; and enzyme activity between certain structures of the brain, particularly in the structures of the brain stem: mesencephalon, diencephalon and the pontine structures.
