The Five 1952 Hodgkin and Huxley Papers

The membrane current at a constant depolarized membrane voltage during a voltage clamp experiment. Adapted from Fig. 11 of Hodgkin et al. (1952).
The membrane current at a constant depolarized membrane voltage, when the axon is immersed in normal seawater (“sodium”) and in an artificial seawater with sodium replaced by choline (“choline”). Adapted from Fig. 1 of Hodgkin & Huxley (1952).
The membrane current (blue) and conductance (green) during a brief voltage clamp experiment. Adapted from Fig. 8c of Hodgkin & Huxley (1952).
The membrane voltage (red) and current (blue) during a two-step voltage clamp protocol. Adapted from Fig. 4 of Hodgkin & Huxley (1952).
The calculated (top) and measured (bottom) action potential. Adapted from Fig. 12 of Hodgkin & Huxley (1952).
