Abstract
A method for providing electrical stimulation to a user, the method comprising: providing an electrical stimulation device, in communication with a controller, at a head region of the user; with the electrical stimulation device, providing a stimulation treatment having a waveform configured for neuromodulation in the user; with the controller, performing an adjustment to the stimulation treatment, wherein performing the adjustment includes: generating a transformed waveform with application of a transfer function to the waveform, wherein the transfer function scales the waveform and selectively attenuates extreme waveform values while maintaining a frequency characteristic of the waveform in the transformed waveform; and applying the transformed waveform with the electrical stimulation device, thereby modulating the stimulation treatment.
Core Innovation
The invention relates to neuromodulation electrical stimulation delivered by an electrical stimulation device located at a head region of a user, with the device in communication with a controller. The controller provides and modifies a stimulation treatment by generating and applying waveforms configured for neuromodulation, and the waveform comprises a superposed waveform including superposition of two or more frequency-band components selected from delta-band, theta-band, alpha-band, gamma-band, and beta-band components.
In near-real time and in response to an adjustment determined by the controller, the controller generates a transformed waveform by applying a transfer function to the waveform. The transfer function scales the waveform and selectively attenuates extreme waveform values while maintaining a frequency characteristic of the waveform in the transformed waveform, and the transformed waveform is applied with the electrical stimulation device to modulate the stimulation treatment in near-real time.
The disclosure includes adjustment behavior responsive to neurological signatures, neurological states, or neurological metrics, including biological parameters indicative of a cognitive state and comparisons to a threshold condition. The stimulation treatment can include superposed theta-band and gamma-band frequency components, and the adjustment includes generating the transformed waveform for application.
Claims Coverage
The partial content includes two independent claims. Across these independents, the coverage centers on a head-region stimulation device delivering a superposed multi-band waveform and a controller that generates and applies a transformed waveform in response to an adjustment, including transfer-function-based waveform transformation and near-real-time modulation.
