摘要： Bioelectrical signals may be sensed within the brain by two or more electrodes to determine characteristics of a function of the brain. The signals obtained by the electrodes may be plotted over time to determine whether the brain function exhibits a normal or an abnormal pattern. If the brain function exhibits an abnormal pattern, an implantable medical device may dynamically determine based on the abnormal pattern and a previously-obtained plot associated with normal brain function, an appropriate electrical stimulation therapy. Application of the appropriate electrical stimulation therapy causes the brain function to shift from the abnormal pattern to the normal pattern.

摘要： This disclosure describes techniques for delivering electrical stimulation at one or more phases relative to an ongoing oscillating signal in a patient, and then mapping the response to the oscillating signal. The techniques may reduce or eliminate the oscillating signal. In one example, the disclosure is directed to a method that includes delivering a set of first electrical stimulation at a plurality of phases relative to an oscillating signal, measuring a response in the oscillating signal to the set of first electrical stimulation after delivering electrical stimulation at each respective phase of the plurality of phases, determining a phase at which to deliver second electrical stimulation based on the measured responses, and delivering the second electrical stimulation to the patient at the determined phase to produce a therapeutic effect.

摘要： Various embodiments concern sensing a LFP signal from one or more electrodes, measuring the amplitude of the signals over a period of time, and calculating a plurality of variance values from the amplitude, wherein each of the variance values correspond to the variance of the amplitude for a different interval of time of the period of time with respect to the other variance values. Such embodiments may further include assessing the relative level of neural activation of an area of the brain based on the variance values, wherein the area of the brain is assessed to have a relatively higher level of neural activation when the variance is relatively higher and the area of the brain is assessed to have a relatively lower level of neural activation when the variance is relatively lower.

摘要： The disclosure relates to the delivery of electrical stimulation therapy to the brain of a patient, e.g., to treat or otherwise manage a patient disorder. In one example, the disclosure relates to a method comprising generating electrical stimulation via a medical device; delivering the electrical stimulation at a first frequency to a brain of a patient when the bioelectrical brain signals of the patient oscillate at a second frequency, where the second frequency corresponds to pathological brain signals of the patient, where the electrical stimulation is selected to entrain the bioeiectrical brain signals of the patient; and adjusting the delivered electrical stimulation from the first frequency to a third frequency, where adjusting the delivered electrical stimulation changes the bioelectrical brain signal oscillations to a fourth frequency different from the second frequency. The fourth frequency may correspond to an oscillation frequency of non-pathological brain signals of the patient.
