Pilots have noticed that when the sun is viewed through an idling propeller one can be subjected to an unusual form of vertigo. This is apparently due to an interaction of the flickering light and certain rhythmic electrical activity taking place in the brain. Other such phenomena that may occur when a man is placed in an unusual environment suggest the investigation of the nature of brain rhythms, especially in regard to malfunction. It has been found that almost all of the well-known phenomena of nonlinear oscillations have counterparts in the macroscopic neuroelectric behavior of the human brain. These correspondences permit the construction of a very suggestive phenomenological theory to explain electroencephalographic data in terms of nonlinear stability which in turn reveals unsuspected relationships in the data and suggests new experiments.
