1. A method for treating neurological dysfunction, comprising:

  • determining that a patient'"'"'s neurological disorder, not caused by external electrical stimulation, affects an aspect of the patient'"'"'s movement other than the patient'"'"'s gait and the patient'"'"'s oral functioning;

    based at least in part on determining that the neurological disorder affects an aspect of a patient'"'"'s movement other than the patient'"'"'s gait and the patient'"'"'s oral functioning, treating the patient'"'"'s disorder by implanting at least one electrode device so that a first electrical contact is over one of the motor cortex, the prefrontal cortex and the supplementary motor area of the patient'"'"'s brain, and a second electrical contact is over another of the motor cortex, the prefrontal cortex and the supplementary motor area, at least one of the first and second electrical contacts being positioned at a region of the patient'"'"'s brain that is located between the interhemispheric fissure and the Sylvian fissure of the patient'"'"'s brain, both the first and second electrical contacts being positioned within the patient'"'"'s skull, proximate the dura mater and outside a cortical surface of the patient'"'"'s brain; and

    applying electrical stimulation to the patient'"'"'s brain via the at least one electrode device, independently of the patient'"'"'s brain activity level immediately prior to applying the stimulation.
