Comparative observation of the action potential of autonomic nerve with E.E.G.

Correlation between the brain and the autonomic nerves have been studied by many authors from anatomical as well as physiological stand points, but still many there are left to be clarified. A great number of articles of E.E.G. have been published after the discovery of E.E.G. by Berger, and contributed much both to the brain physiology and clinical medicine. On the other hand, enormous advance in our understanding of the action potentials of peripheral nerves was established by many investigators following the brilliant works by Er langer & Gasser. Standing on such a ground of recent advance in neurophysiology, correlations of brain and peripheral nerves were studied by some authors, that is, studies of brain and cord by Davis etc.,1),2),3),4) those of brain and peripheral nerves by Gibbs,5) Gellhorn,6) and those concerning brain and autonomic nerves including vagus by Bailey & Bremer,7) Darrow etc.8) As I studied the action potentials of brain, (E.E.G.) as related to those of autonomic nerves, some results obtained thereby I shall report here.
