"the nervous system is essentially an electrical aparatus using very low powerlevels"
Signal propagation in neurons is not by electrical conduction, in the wire sense, i believe that this would actually be incredibly slow for the conductivities / currents involved. Rather signals are transmitted by an active chemical process where potassium ions are pulled into and out of the axon in serquence: http://en.wikipedia.org/wiki/Action_potential.
I'm not sure that this has a direct implication for any kind of interference effect, but just wanted to point out that nerves don't really work like metal wires so how external fields effect the internal currents is not trivial. Also skin-depth/screening is going to play a big role in stopping most of the external radiation.
