Abstract: Systems and methods for providing electrostimulation to a neural target are discussed. An example system comprises an implantable stimulator and a controller. The implantable stimulator can provide burst stimulation comprising a pulse train followed by a pulse-free period. The controller can detect an indication of frequency drift of an intrinsic oscillatory neural activity, and in response to the indication of frequency drift, calibrate a burst stimulation parameter including a burst frequency or a timing for initiating the burst stimulation at a particular phase of an oscillation cycle of the intrinsic oscillatory neural activity. The controller can generate a control signal to the implantable stimulator to generate burst stimulation in accordance with the calibrated burst stimulation parameter.

The sensing circuit is configured to sense one or more neural signal representative of neural activity of a subject when connected to an implantable electrode of the one or more implantable electrodes, and the memory is to store a reference signal that is representative of a neural response associated with a state of arousal at or near an anatomical location of the implantable electrode. The processing circuitry is configured to compare the one or more sensed neural signals to the reference signal, and to determine a depth of anesthesia of the subject according to the comparison of the one or more sensed neural signals and the reference signal.

Abstract: Methods and systems for using sensed evoked neural responses for informing aspects of neurostimulation therapy are disclosed. Electrical signals may be recorded during the provision of electrical stimulation to a patient's neural tissue. The electrical signals may be processed and analyzed using one or more classification criteria to determine if the electrical signals contain a neural response of interest. Examples of such neural responses include evoked neural responses that are oscillatory and/or resonant in nature. If the electrical signals include such responses of interest, one or more features may be extracted from the signals and used as biomarkers for informing aspects of neurostimulation therapy, such as directing lead placement, optimizing stimulation parameters, closed-loop feedback control of stimulation, and the like. Various methods and systems described herein are particularly relevant in the context of multi-site stimulation paradigms, such as coordinated reset neuromodulation.

Abstract: Methods of providing electrical neural modulation to a patient's brain are disclosed herein. The methods involve differentially modulating two or more target regions of the brain. For example, a first target region may be provided with an electrical neural modulation signal that activates that target region while a second target region is provided with an electrical neural modulation signal that suppresses or deactivates that target region. As the implantable pulse generators (IPGs) described herein include independent current sources, such differential modulation can be provided with a single IPG.

The programming system may be configured to translate the block sequence descriptions into neuromodulator instructions and wireless communicate the neuromodulator instructions to the neuromodulator for use by the neuromodulator to deliver the neuromodulation to each of the at least two neuromodulation sites.
