ABSTRACT
The ow of electrical current along nerves Now nerve fi bres, with their conductive central core of axoplasm surrounded by an insulated membrane often reinforced with extra non-conductive layers of myelin, are clearly very like ordinary insulated wires: if you apply a voltage at one end, current fl ows down the core and
should make the other end change its voltage as well, and thus trigger transmitter release. Could nerve signals simply be transmitted by this kind of passive conduction, in the same way that messages pass along a telephone wire?
