The human brain works with the help of biological electricity. It receives bioelectric energy from the whole body and itself. The two hemispheres of the brain concentrate energy in different ways. The left hemisphere concentrates electrical impulses with a negative charge, and the right hemisphere – the ones with a positive charge. The potential difference results in a manifold increase of the incoming electrical energy of low-frequency waves. But there is also…. read more
