1. A method of treating a patient with conductive aphasia caused by an abnormally functioning arcuate fasciculus that hinders communication between a Broca'"'"'s area and a Wernicke'"'"'s area of the patient'"'"'s brain, comprising:

  • providing at least one System Control Unit (SCU) controllably connected to one or more electrodes and/or infusion outlets;

    implanting the one or more electrodes and/or infusion outlets in or adjacent to the Wernicke'"'"'s area;

    measuring an attempted speech production of the patient and transmitting a corresponding signal to the SCU; and

    activating the SCU in response to the transmitted signal to control delivery of a stimulus from the one or more electrodes and/or infusion outlets to the Wernicke'"'"'s area to circumvent the communication role of the arcuate fasciculus, thereby treating or reducing an occurrence or severity of a symptom of the conductive aphasia.
