Did some calculations the other day for a EE class...

results were somewhat interesting.

I calculated the average voltage across a brain cell of 10um in
diameter due to a 60Hz B field of 1uT -  (about that from
a VERY close powerline).

Came out to around 200 pV.

For a 60 Hz E field of about 1kV/m,( i think in a storm this
can get as high as 1000kV/m)
i got about 70 pV for a cell in the body  - conductivity ~ 1S/m

All VERY tiny voltages, considering the signal voltages on a
brain cell are around 100mV, signals range from 1 - 100 Hz, 
i think.

Incedentally, p means 10^-12, u =10^-6, m=10^-3.

In short, its bunk.  (according to my EE prof, anyways)
And IKEA means sucker in Eskimo :)
But what do I know anyways? I'm sure there are quantum
relativistic effects that i'm not aware of.
