Claim One:
1. The method for applying an electrical stimulus transcranially about an animal with surface regions located adjacent a volume of tissular material, comprising the steps of: (a) providing first and second electrode assemblies of respective first and second polarities; (b) providing electrical generation apparatus electrically coupled with said first and second electrode assemblies, responsive to a generator input to provide an excitation output across said first and second electrode assemblies at frequencies and with waveforms exhibiting given electrical characteristics; (c) providing a current sensor assembly responsive to said electrical excitation outputs for providing a monitored current value output; (d) providing a voltage sensor assembly responsive to said electrical excitation outputs for providing a monitored voltage value output; (e) providing a controller having a memory, and a display and controllable to derive a said generator input for producing said excitation output exhibiting predetermined said frequencies and waveforms; (f) electrically coupling said first electrode assembly to a first said skin surface region; (g) electrically coupling said second electrode assembly to a second said skin surface region spaced from said first skin surface region; (h) controlling said controller to derive a said generator input to produce a said excitation output across said tissular volume for a predetermined application interval such excitation output having electrical characteristics defining a said waveform with positive-going and negative-going waveform components combined to exhibit substantially no d.c. term and occurring at a base frequency value and at a burst repetition frequency value less than said base frequency value; (i) controlling said controller to record in said memory said monitored voltage output as voltage data corresponding with said electrical characteristic; and (j) controlling said controller to record in said memory said monitored current output in correspondence with said monitored voltage output as current data corresponding with said electrical characteristics and influenced by the impedance characteristics extant at said volume of tissular material.
