With the remarkable pioneering of the Cambridge and St. Louis schools of neurophysiology, most of the mystery of the working mechanism of single axons was unraveled and reduced to the level of simplicity and reliability of a mathematical equation. Berger's introduction, in 1929, of a method of observation applied to the baffling complexity of neuronal aggregates, was, at the same time, fascinating and discouraging. The fact that the science of electroencephalography received immediate clinical application, before the fundamental nature of brain waves was investigated, that, in other words, the pioneer electroencephalographer of two score years ago was deluged with a multitude of practical inquiries before the ink was dry on the first record ever taken, gives us only the measure of avidity for knowledge of those to whom this book is dedicated: neurologists, internists, pediatricians, psychiatrists, and neurosurgeons. Electroencephalography grew up in our time, and members of the medical profession
