摘要:
The following disclosure describes several methods and apparatus for stimulating cells implanted in the regions of nervous system, such as the brain, spinal cord or peripheral nerves. Accordingly, the functionality of the cells can be improved, for example, by differentiating undifferentiated or partially undifferentiated cells into neurons or other cells having action potentials. The method can also include promoting directional growth and connectivity of fully differentiated neural cells implanted in a patient's nervous system through electrical enhancement, for example, electrical stimulation via an anode and cathode. 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).

摘要:
Disclosed are several apparatuses and methods for applying intracranial electrical stimulation to treat or enhance the neural function of the patient. In accordance with the invention, intracranial electrical stimulation can be administered to treat brain damage, brain disease, and/or brain disorders. Additionally the intracranial electrical stimulation can be applied to a normal healthy brain to enhance neural-function or control sensory functions. The electrical stimulation site(s) of the brain are located where neuroplasticity is occurring, expected to occur, or in a region where neuroplasticity is not occurring. The intracranial stimulation is expected to produce a lasting effect on the intended neural activity by applying subthreshold stimulation to the increasing the resting membrane potential of the neurons at the stimulation site.
摘要:
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.

摘要:
The following disclosure describes a method for intracranial electrical stimulation to treat or otherwise effectuate a change in neural-functions of a patient. Several embodiments 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 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 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).

摘要:
A device and method for intracranial electrical stimulation to effectuate a change in neural-functions of a patient, by electrical stimulating the brain at a site where neuroplasticity is occurring or is expected to occur, where 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 is related to the neural-function occurs in the brain, identifying the location where such neuroplasticity is present or expected to occur. Where neuroplasticity is not occurring in the brain, an alternative aspect is to induce neuroplasticity at a stimulation site where it is expected to occur. The methods can use electrical pulses that increase the resting membrane potential of neurons at the stimulation site to a subthreshold level.
