Methods and apparatus for effectuating a lasting change in a neural-function of a patient
View Patent ↗The present disclosure suggests methods of selecting a stimulation site for stimulating a patient's brain or methods of effectuating a neural-function of a patient associated with an impaired body function. In one exemplary implementation, such a neural function may be effectuated by selecting a stimulation site, positioning at least a first electrode at the stimulation site, and applying an electrical potential to pass a current through the first electrode. If one aspect, this stimulation site may be selected by a) identifying a second body function that is a corollary to the impaired body function, and b) determining a corollary location of the patient's brain that is associated with the second body function and is ipsilateral to the impaired body function.
1. A method of effectuating a neural-function of a patient that has an impaired body part affected by damage to a first location of a first hemisphere of a brain of the patient, comprising:
selecting a stimulation site by (a) generating an intended neural activity by triggering a neural signal from the impaired body part the impaired body part being external to the brain, (b) detecting a second location of the brain in which a response neural activity occurs in reaction to the neural signal, the second location being in a second hemisphere of the brain that is contralateral to the first hemisphere, and (c) selecting the stimulation site to be at least proximate to the second location;
positioning at least a first electrode at the stimulation site; and
applying an electrical potential to pass a current through the first electrode.
2. The method of claim 1 wherein triggering a neural signal comprises passively moving the body part impaired by the damage to the first location.
3. The method of claim 1 wherein triggering a neural signal comprises applying an electrical stimulation to the body part impaired by the damage to the first location.
4. The method of claim 1 wherein selecting the stimulation site further comprises detecting a third location of the brain in which a response neural activity occurs in reaction to the neural signal, the third location being in the first hemisphere.
