If an Electromagnetic Pulse (EMP) Device disrupts electrical interactions, why is the human body/nervous system unaffected? Or, if it is affected, in what way?

There's a bit of a misconception when people talk about electrochemical reactions in an organism.  These are not electrical as we think of them in wires.  They are dependent on differences in concentrations of sodium and potassium.  Since these are ions, there is a voltage difference across the membrane of a neuron.  However, the propagation of the signals is not a stream of electrons like in a wire.  Rather, the electrochemical difference of sodium and potassium inside and outside of the neuron causes adjacent sodium channels to be activated down the neuron.

I am drunk and on mobile, so hopefully someone jumps in with more specifics.
