Based on the potassium channel "origami windmill" model, and the conservation law of cell membrane area and ion inequality equation of based on the potassium channel "origami windmill" model, and Maxwell's electromagnetic theory, it is theoretically proved that neurons can generate electromagnetic waves. The electromagnetic wave is an energy wave, never disappear. The neurons are equivalent to the built-in antennas of the brain, and information transmission between neurons is conducted wirelessly. The material basis for neurons to generate electromagnetic waves is the result of the exchange of cations on the inner surface of the cell membrane, especially Na+ and K+； The essence of consciousness should be electromagnetic wave. The conclusion that "neurons can produce electromagnetic waves" overturns the view that "electricity→chemistry→electricity" conducts information between neurons, and provides theoretical support for humans to finally solve the mysteries of the brain. At the same time, seven falsificationist methods are given. The brain is a huge gold mine, and it is too important to crack the mystery of the brain. It should be a joint operation of "multiple arms". It should not only be the work of brain scientists, but also the participation of physicists, chemists and mathematicians.
