20080215112 | METHODS AND APPARATUS FOR EFFECTUATING A LASTING CHANGE IN A NEURAL-FUNCTION OF A PATIENT - The following disclosure describes several methods and apparatus for intracranial electrical stimulation to treat or otherwise effectuate a change in neural-functions of a patient. Several embodiments of methods in accordance with the invention are directed toward enhancing or otherwise inducing a lasting change in neural activity to effectuate a particular neural-function. Such lasting change in neural activity is defined as “neuroplasticity.” The methods in accordance with the invention can be used to treat brain damage (e.g., stroke, trauma, etc.), brain disease (e.g., Alzheimer's, Pick's, Parkinson's, etc.), and/or brain disorders (e.g., epilepsy, depression, etc.). The methods in accordance with the invention can also be used to enhance neural-function of normal, healthy brains (e.g., learning, memory, etc.), or to control sensory functions (e.g., pain). Certain embodiments of methods in accordance with the invention electrically stimulate the brain at a stimulation site where neuroplasticity is occurring. The stimulation site may be different than the region in the brain where neural activity is typically present to perform the particular neural function according to the functional organization of the brain. In one embodiment in which neuroplasticity related to the neural-function occurs in the brain, the method can include identifying the location where such neuroplasticity is present. In an alternative embodiment in which neuroplasticity is not occurring in the brain, an alternative aspect is to induce neuroplasticity at a stimulation site where it is expected to occur. Several embodiments of these methods that are expected to produce a lasting effect on the intended neural activity at the stimulation site use electrical pulses that increase the resting membrane potential of neurons at the stimulation site to a subthreshold level. | 09-04-2008 |
20090171416 | METHODS AND APPARATUS FOR EFFECTUATING A LASTING CHANGE IN A NEURAL-FUNCTION OF A PATIENT - Methods and apparatus for treating an impaired neural function in a brain of a patient. In one embodiment, a method for treating a neural function in a brain of a patient includes determining a therapy period during which a plurality of therapy sessions are to be performed to recover functional ability corresponding to the neural function. The method continues by identifying a stimulation site in or on the brain of the patient associated with the neural function, and positioning an electrode at least proximate to the identified stimulation site. The patient is then treated by providing electrical stimulation treatments to the stimulation site. The treatment can comprise delivering electrical stimulation signals to the electrode during the therapy sessions. After expiration of the therapy period, the method includes preventing electrical stimulation signals from being delivered to the stimulation site. | 07-02-2009 |
20090319000 | METHODS AND APPARATUS FOR EFFECTUATING A CHANGE IN A NEURAL-FUNCTION OF A PATIENT - The present disclosure is directed generally to methods and apparatus for effectuating a change in a neural function of a patient. A method in accordance with a particular embodiment includes implanting an electrode at a cortical stimulation site selected to promote recovery of the affected neural-function, with the cortical stimulation site being at least proximate to the cortex. The method can further include estimating a threshold for the specific patient at which an electrical signal delivered via the implanted electrode directly triggers a neural reaction associated with the stimulation site in response to the delivered electrical signal, and electrically stimulating the cortical stimulation site by Passing an electrical current through the electrode. | 12-24-2009 |
