A method of providing electrical stimulation therapy to a patient according to one embodiment includes generating an un-tuned electrical noise signal by at least one noise generator, partitioning the un-tuned electrical noise signal into a plurality of discrete frequency bands having corresponding bandwidths, delivering the un-tuned electrical noise signal through one or more electrodes to the patient to target the patient's central or peripheral nervous system, adjusting, for each of a plurality of selected frequency bands, an amplitude of the voltage or current of the un-tuned electrical noise signal within a corresponding frequency band to generate an adjusted electrical stimulation signal based on feedback received from the patient, wherein the adjusted electrical stimulation signal includes a plurality of local maxima and a plurality of local minima, and delivering the adjusted electrical stimulation signal through the electrodes to provide electrical stimulation therapy to the patient.

A method for subcutaneously treating pain in a patient includes first providing a neurostimulator with an IPG body and at least a primary, a secondary, and a tertiary integral lead with electrodes disposed thereon. A primary incision is opened to expose the subcutaneous region below the dermis in a selected portion of the body. A pocket is then opened for the IPG through the primary incision and the integral leads are inserted through the primary incision and routed subcutaneously to desired nerve regions along desired paths. The IPG is disposed in the pocket through the primary incision. The primary incision is then closed and the IPG and the electrodes activated to provide localized stimulation to the desired nerve regions and at least three of the nerves associated therewith to achieve a desired pain reduction response from the patient.

The headset can comprise a left junction and a right junction, a plurality of length-adjustable bands connecting the left junction and the right junction, and a number of electrodes. Each of the electrodes can comprise an electrode body coupled to one of the plurality of length-adjustable bands and a detachable electrode tip configured to be detachably coupled to the electrode body. The electrode tip can comprise an electrode tip body, one or more deflectable electrode legs coupled to the electrode tip body, and a conductive cushioning material coupled to a segment of at least one of the one or more electrode legs.

Systems including intra-calvarial implants and/or subdermal implants are capable of stimulating cortical regions and sensing and electrical signals is implanted within or on a calvarial bone of a skull. The implants have current steering capability to change the current density profiles applied to selected cortical regions underlying the implant. The systems may track changes in the position and/or spatial parameters of a neural network by recording cortical electrical signals and processing them to compute the values of one or more network activity biomarkers. The systems may spatially track changes detected in network anatomical position and deliver the stimulation of the cortex to the network detected position by using current steering methods.

Apparatus is provided that includes a two-dimensional arrangement (70) of extracranial electrodes (30), configured to be placed outside and in electrical contact with a skull of a subject identified as at risk of or suffering from a disease; and a cerebrospinal fluid (CSF) electrode (32), configured to be implanted in a ventricular system of a brain of the subject. Control circuitry is configured to drive the extracranial and the CSF electrodes (30, 32) to clear a substance from brain parenchyma of the subject into at least one region of the brain selected from the group consisting of: a subarachnoid space of the brain and dural sinuses of the brain. Other embodiments are also described.

Universal switch modules, universal switches, and methods of using the same are disclosed, including methods of preparing an individual to interface with an electronic device or software. For example, a method is disclosed that can include measuring brain-related signals of the individual to obtain a first sensed brain-related signal when the individual generates a task-irrelevant thought. The method can include transmitting the first sensed brain-related signal to a processing unit. The method can include associating the task-irrelevant thought and the first sensed brain-related signal with N input commands. The method can include compiling the task-irrelevant thought, the first sensed brain-related signal, and the N input commands to an electronic database.

A balance prosthesis device for an individual including a sensor module configured to obtain a sensor signal indicative of a balance or equilibrium state of the individual, a processing module configured to determine at least one neurostimulation signal based at least in part on the obtained sensor signal, and a transmitter module configured to transmit the determined neurostimulation signal to a neurostimulation device of the individual. The neurostimulation signal is configured to elicit an artificial sensation in a specific sensory cortex area of the individual via directly stimulating afferent sensory axons of the central or peripheral nervous system of the individual targeting sensory neurons of the sensory cortex area not directly associated with vestibulocortical pathways of the individual. The elicited artificial sensation provides a balance indication to the individual in order to support, mimic, substitute or enhance the natural sense of balance of the individual.

Systems and methods for providing neural stimulation and recording on a subject using flexible complementary CMOS probes are provided. Disclosed systems can include a flexible probe adapted for insertion into a portion of a brain of the subject, the flexible probe comprising a tail portion and a head portion. The tail portion can include a plurality of electrodes configured to be coupled to the brain and a plurality of front-end amplifiers. Each of the plurality of front-end amplifiers can be configured to amplify a signal received from a corresponding electrode of the plurality of electrodes. The head portion can include one or more inductors configured to enable two-way communication with a wireless reader through a near-field inductive link.

Systems and methods for promoting neuroplasticity in a brain of a subject to improve and/or restore neural function are disclosed herein. One such method includes detecting residual movement and/or muscular activity in a limb of the subject, such as a paretic limb. The method further includes generating a stimulation pattern based on the detected movement and/or muscular activity, and stimulating the brain of the subject with the stimulation pattern. It is expected that delivering stimulation based on the detected residual movement and/or muscular activity of the limb will induce neuroplasticity for restoring neural function, such as control of the limb. A second method involves detecting brain signals and delivering contingent stimulation. A third method involves delivering pairs of successive stimulus patterns to two brain sites, controlled either by preprogrammed sequences or contingent on neural or muscular activity or movement.
