1. An electrophysiological analysis method applied in a system comprising:
a series of electrodes, intended to be placed in different regions of the human body, a DC voltage source, controlled for increasing the DC voltage square wave pulses, a switching circuit, laid out for selectively connecting a pair of so-called active electrodes to the voltage source, said active electrodes forming an anode and a cathode, and for connecting at least one of the passive electrode in high impedance being used for measuring the potential attained by the body, and a measuring circuit laid out for measuring representative data of the current in the active electrodes and potentials on at least certain electrodes connected in high impedance in response to the application of the square waves, said data allowing determination of a value of the electrochemical conductance of the skin, the method comprising at least one measuring step during which the adjustable voltage source applies to the anode a series of said road DC voltage square waves, and during which the measuring circuit measures said data, the method being characterized in that it further comprises a step prior to the measuring step, during which an electrode which is connected in high impedance during the measuring step is regenerated by being connected to the voltage source as a cathode. |
