title: The lack of evidence for ELF magnetic-field effects on bilayer membranes and reconstituted membrane channels.
abstract: The effects of low-frequency (10-500 Hz) magnetic fields on the electrical properties of channel-free bilayer membranes, and on the single-channel conductance and macroscopic gating characteristics of porin channels incorporated into membranes, have been studied for field strengths in the range 10-100 microT. The field conditions that could in theory give rise to 'cyclotron resonance' effects were also studied. No evidence has been found to support the concept that cyclotron resonance and membrane ion channel effects are involved in the reported biological effects of ELF magnetic fields.
