Summary
The author describes a method for recording both the electroencephalogram and the summed impulse activity from the same point on the cerebral cortex. As established by experiments on rabbits, a change in the EEG always precedes clear-cut changes in the summed impulse activity. Intensification of the impulse, activity was observed against a background of desynchronization and against a background of “regular rhythm.” This leads to the conclusion that the EEG is not the result of algebraic summation of the impulse activity of a large number of nerve cells.
