One aspect of the present disclosure relates to a system that can modulate the intensity of a neural stimulation signal over time. A pulse generator can be configured to generate a stimulation signal for application to neural tissue of an individual and modulate a parameter related to intensity of a pattern of pulses of the stimulation signal over time. An electrode can be coupled to the pulse generator and configured to apply the stimulation signal to the neural tissue. A population of axons in the neural tissue can be recruited with each pulse of the stimulation signal.

A tinnitus masking system for use by a person having tinnitus. The system comprises a sound delivery system having left and right ear-level audio delivery devices and is configured to deliver a masking sound to the person via the audio delivery devices such that the masking sound appears to originate from a virtual sound source location that substantially corresponds to the spatial location in 3D auditory space of the source of the tinnitus as perceived by the person. The masking sound being represented by left and right audio signals that are converted to audible sound by the respective audio delivery devices.

A method for treating neural disorders is provided, The method includes the following operation. A stimulation is delivered to a layer of a cortex of a patient with a neural disorder, wherein the stimulation is delivered to less than all layers of the cortex of the patient. In another method for treating neural disorders, a stimulation is delivered to a cortex of a patient with a neural disorder, wherein the stimulation delivered to one of a plurality of layers of the cortex is stronger than to other layers of the cortex. The system for treating neural disorder is also provided. The system includes a stimulation signal generator and a layer-specific stimulation means. The layer-specific stimulation means is coupled to the stimulation signal generator, configured to deliver a stimulation to a specific layer of a cortex of a patient with a neural disorder.

A method of generating sounds for reducing an effect of tinnitus is disclosed. The method includes the following steps: acquiring a sound frequency of a tinnitus sound of a user, and playing a plurality of pure tones within a frequency range during a playback time, wherein the plurality of pure tones include a plurality of first pure tones and a plurality of second pure tones; the plurality of first pure tones and the sound frequency are located at a first frequency area, and the plurality of second pure tones are located at a second frequency area; the first frequency area covers X Hz, where 100X12000, the second frequency area covers the remaining portion of the frequency range excluding the first frequency area, and the plurality of first pure tones accounts for M % of the plurality of pure tones, where 50<M90.

Electrical stimulation devices can be used to treat tinnitus. For example, tinnitus can be treated using implantable electrodes and stimulation devices for delivering electrical stimulation to a patient's cochlear region. Cochlear surface electrode(s), endosteal electrode(s), subendosteal electrode(s), intraosseous electrode(s), or short intracochlear electrode(s) (or a combination thereof), connected to existing or modified cochlear implant receiver/stimulator technology, can provide a successful model for long-term treatment of tinnitus in a large number of patients. In some cases, patients can simply turn on the tinnitus implant when experiencing troublesome tinnitus and gain instant relief

An electrical stimulation system that provides for transtympanic stimulation of the inner ear that can be used for safely and effectively treating tinnitus. The electrical stimulation system of the present invention may be fully implantable or partially implantable. The system features an electrode placed on the round window membrane. An external portion provides the power to the electrode, which can stimulate the inner ear via the round window as needed by the patient. The present invention also features methods of treating tinnitus using the electrical stimulation system described herein.

A device for stimulating neurons that includes a stimulation unit implantable in the body of a patient and having stimulation elements that stimulate neurons in the brain and/or spinal cord. A control unit controls the stimulation unit during first and second time intervals in different stimulation modes. The control unit controls the stimulation unit during 75% or more of the first time interval in the first stimulation mode to repeatedly generate sequences of stimuli and the order in which the stimulation elements generate stimuli is constant for not more than 5 successively generated sequences and then varied. The control unit controls the stimulation unit during 75% or more of the second time interval in a second stimulation mode such that the stimulation elements repeatedly generate sequences of stimuli and the order in which the stimulation elements generate stimuli is constant for at least 25 successively generated sequences and then varied.
