As predicted by Hodgkin (1975), calculation of conduction velocities in squid giant axons shows that if each sodium channel is gated by charged particles moving in the membrane field there will be a maximum in the relation between sodium conductance and conduction velocity.

Patch pipettes were used to record the current arising from small populations of sodium channels in voltage-clamped cut-open squid axons. The current fluctuations associated with the time-variant sodium conductance were analyzed with nonstationary statistical techniques in order to obtain an estimate for the conductance of a single sodium channel. The results presented support the notion that the open sodium channel in the squid axon has only one value of conductance, 3.5 pS.
