[Possible mechanism of generation of the magnetoencephalogram]

Various cases of local currents axial symmetry violations such as: 1) bent fibres, 2) fibres located on the boundary between tissues of various conductivities, or 3) spiral fibres were considered as possible sources of the magnetic field. It is supposed that the magnetic moments of the spikes in bent or spiral fibres originate magnetoencephalogram (MEG) and therefore MEG may serve as an index of the summary impulsing activity in human brain. Our explanation of MEG contradicts to Lippold's hypothesis on non-neural nature of alpha-rhythm.
