Abstract:
1. A method for electrostimulation comprising: providing a first electrode set comprising at least one electrode; providing a second electrode set comprising at least three electrodes, wherein the number of electrodes in the second electrode set is greater than the number of electrodes in the first electrode set; locating the first and the second sets of electrodes in a target area, the target area consisting of the exposed surface of the head and areas associated with the head of a subject; surrounding the first electrode set with the second electrode set, such that said electrodes of the second electrode set define a shape that surrounds the at least one electrode of the first electrode set; and delivering electric current from at least one electronic source to each of the electrodes in the first and second electrode sets, wherein all of the electrodes of the first electrode set are provided with a first electrical polarity opposite of a second electrical polarity provided to all of the electrodes of the second electrode set, and wherein no additional electrodes having a substantial current on the exposed surface of the head of said first polarity are provided outside said shape defined by said second electrode set, unless said additional electrodes are surrounded by electrodes having a substantial current of said second polarity, such that all electrodes provided on the exposed surface of the head and areas associated with the head of a subject having said first polarity and a substantial current are surrounded by electrodes having said second polarity, and wherein the total current delivered to the electrodes of the first electrode set is substantially equal in magnitude to the total current delivered to the electrodes of the second electrode set.
