  • Publication number: 20080046035
    Abstract: Electrode configurations for reducing invasiveness and/or enhancing neural stimulation efficacy, and associated methods, are disclosed. A method in accordance with one embodiment of the invention for treating a brain disorder includes identifying a target neural structure within a patient's skull and implanting an electrode device within the patient's skull so that an axis that is generally normal to the skull proximate to the electrode device and that passes through at least one electrical contact of the electrode device is offset from the target neural structure. The method further includes stimulating the target neural structure by applying an electrical signal to the at least one electrical contact. In particular embodiments, the electrode device can be positioned between, along, across, or adjacent to a fissure, recess, groove, and/or vascular structure of the patient's brain.

  • Publication number: 20080039895
    Abstract: Electromagnetic signal delivery for tissue affected by neuronal dysfunction, degradation, damage, and/or necrosis, and associated systems and methods are disclosed. A method in accordance with one embodiment of the invention includes identifying an affected region, with the affected region including neuronal tissue that, at least during a pre-dysfunctional period, was in neural communication with neuronal tissue in a dysfunctional region. The affected tissue can be functionally adversely affected by neuronal dysfunction in the dysfunctional region. The method can further include applying electromagnetic signals to the neuronal tissue in the affected region. For example, the electromagnetic signals can be applied to a hypo-active neural region that is not physically damaged, and has been identified as likely to recover at least in part as a result of electromagnetic signals. Signals can be applied at sub-threshold levels to cortical and/or subcortical regions.

  • Publication number: 20070265489
    Abstract: Methods for establishing parameters for neural stimulation, including via performance of working memory tasks, and associated kits, are disclosed. A method in accordance with one embodiment includes engaging a patient in a function controlled at least in part by a target neural population, and applying electromagnetic signals to the target neural population. A target parameter in accordance with which the electromagnetic signals are applied is adjusted, based at least in part on a characteristic of the patient's performance of the function. Electromagnetic signals are applied to the patient with the adjusted target parameter, and the patient's response to the electromagnetic signals, including the characteristic of the patient's performance, is evaluated.

  • Publication number: 20070179558
    Abstract: Systems and methods for varying electromagnetic and adjunctive neural therapies are disclosed. A method in accordance with one embodiment includes applying electromagnetic signals to a target neural population of a patient over a first period of time in accordance with a first mode (e.g., including signal delivery to the central nervous system or peripheral nervous system, via implanted or non-implanted devices). The method can further include applying electromagnetic stimulation to the patient over a second period of time in accordance with a second mode different than the first mode. Varying the mode between the first period of time and second period of time can increase the efficacy and/or longevity of the stimulation. Systems in accordance with other embodiments can support multiple signal delivery devices.

    Abstract: Systems and methods for enhancing or affecting neural stimulation efficiency and/or efficacy are disclosed. In one embodiment, a system and/or method may apply electromagnetic stimulation to a patient's nervous system over a first time domain according to a first set of stimulation parameters, and over a second time domain according to a second set of stimulation parameters. The first and second time domains may be sequential, simultaneous, or nested. Stimulation parameters may vary in accordance with one or more types of duty cycle, amplitude, pulse repetition frequency, pulse width, spatiotemporal, and/or polarity variations. Stimulation may be applied at subthreshold, threshold, and/or suprathreshold levels in one or more periodic, aperiodic (e.g., chaotic), and/or pseudo-random manners. In some embodiments stimulation may comprise a burst pattern having an interburst frequency corresponding to an intrinsic brainwave frequency, and regular and/or varying intraburst stimulation parameters.

  • Publication number: 20030125786
    Abstract: 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. Certain embodiments of methods in accordance with the invention electrically stimulate the brain at a stimulation site where neuroplasticity is occurring or is expected to occur. 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 or expected to occur. 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.
