A method for desynchronizing a pathological neural oscillations, includes identifying a first subpopulation of the neurons involved in the pathological neural oscillation that are in alignment with each other within a predetermined angular stimulation range, and a second subpopulation that are both (A) in alignment with each other within the predetermined angular stimulation range, and (B) out of alignment with the first neurons by at least the predetermined angular stimulation range, and applying electrical stimuli to the first and second subpopulations through scalp electrodes, the electrical stimuli being out of phase with the pathological neural oscillations for desynchronizing the pathological neural oscillations.
