Not really. Nerve activity is a chemical process that dumps charged 
particles out of one end to start the chemical reaction at the other end of 
the next nerve cell. But it's primarily chemical as it travels thru the 
nerve, unlike electricity in wires.

Novocain, for example, works by suppressing the chemical reaction in the nerve.
