1. A system for the electrical stimulation of brain tissue, the system comprising:

  • at least one brain surface electrode;

    at least one deep brain electrode; and

    a control module adapted to provide a stimulation electrical current between the at least one brain surface electrode and the at least one deep brain electrode, the control module having a first terminal and a second terminal, the control module'"'"'s first terminal being electrically coupled to the at least one brain surface electrode and the control module'"'"'s second terminal being electrically coupled to the at least one deep brain electrode, the at least one brain surface electrode and the at least one deep brain electrode being placed in a configuration within the brain tissue so that the stimulation electrical current forms a sheet of electrical current that is applied in the vicinity of the boundary of an epileptic focus that is located within the brain tissue thus depolarizing brain neurons located in the vicinity of the epileptic focus.
