Abstract
I still recall my astonishment when I learned that if you open your eyes the electroencephalogram (EEG) alpha waves will disappear, and that if then you close them the alpha waves will reappear. The year was 1934, and I have been hoping ever since to learn what causes the 10-Hz rhythm in the first place, and then what brain process turns it off and on. The editors of this book have asked me to compare another human brain rhythm—in the region of 40 Hz this time—with a cat rhythm in the same frequency range that is discussed elsewhere in this volume by Gray and Singer and their colleagues, and by Eckhorn and his colleagues. I do as much as I can to oblige them in what follows, first describing some properties of the human 40-Hz phenomena, then comparing these with the microelectrode data from the cat. After concluding that the two differ in several ways, I branch out to consider the general problem of brain rhythms briefly, and to speculate on their possible physiological origins and functions.
