FIELD: medicine. SUBSTANCE: method involves utilizing resonance of magnetic moment precession frequency arising due to ions circumferentially moving in the nerve fiber membrane when moving in permanent electric field, around external permanent electric field and external electromagnetic field frequency. Paramagnetic ion resonance impedance spectrum is recorded under condition the nerve fiber moves as a whole with an organ axially with respect to magnetic inductance vector and biological tissue impedance is measured in Larmore frequency range corresponding to ion transfer processes. EFFECT: enhanced accuracy of diagnosis in vivo. 4 cl, 2 dwg , 1 tbl
