We investigated the interaction characteristics and mechanism of non-ionization low-frequency electromagnetic radiation field and cerebral nervous system. When the two-state physical system in the cytoskeletal microtubule (MT) can be quantized, The state of information bits in cerebral neurous system is described by density matrix, and the system dynamics equation is established and solved. It indicates that when the brain is exposed to non-ionization low-frequency electromagnetic field, non-thermal effect ahnost do not e...
