    摘要： A brain mapping system includes a brain signal acquisition device for collecting brain signals corresponding to different locations of the brain, a stimulator for generating a stimulus based upon a pseudorandom sequence, and a processor for segmenting the brain signals into a plurality of epochs and correlating features extracted from the epochs with the pseudorandom sequence to generate correlation functions, wherein a brain map is constructed by the correlation functions.

    摘要： Provided herein are a method and system are provided for the localization of clinically relevant electrophysiological signals necessary for the proper placement of the electrodes for nervous system stimulation. The system provides electrical and mechanical means to stimulate or excite neural structures in order to elicit specific neural responses. The method can include mechanical vibratory stimulation, cutaneous electrical stimulation, electrical stimulation of the peripheral nerves, or photic stimulation, and recording of local field potentials and extracting evoked potentials in response to stimulation. The method also includes extracting components of the evoked potentials that relate the signal in the evoked potentials to specific anatomical structures and localization of the source of the evoked potentials recorded so as to identify the location of the source relative to the recording electrode with high resolution by sampling the evoked potentials with a relative large (macro) electrode that is moved in small incremental steps.

    摘要： The present application is a neurological feedback system and method. The neurological feedback provides a trigger event to evoke a first neurological response from the brain of a user and a feedback event to evoke a second neurological response from the brain of a user to counter the first neurological response. As such, when the trigger event evokes a positive first neurological response, such that, for example, dopamine is released by the brain, the feedback event evokes a negative second neurological response, such that, for example, less or no dopamine is released by the brain in response the trigger event (and the converse). The neurological feedback may be useful to break additions or train a brain not to crave certain things.

    摘要： A neural event process, including receiving a neural response signal, decomposing the signal using at least one wavelet, differentiating phase data of the wavelets and the response signal to determine maxima and minima of the phase data and the signal, and processing the maxima and minima to determine peaks representing neural events.

    摘要： A method for delivering electrical stimulation to alter a cognitive state of a user, the method comprising: monitoring a brain signal from the user via one or more intracranial electrodes implanted in the brain of the user while the user is presented with a stimulus; comparing the brain signal to a testing phase biomarker, wherein the testing phase biomarker is derived from a cognitive test performed on a contributor during a testing phase; delivering electrical stimulation to a brain of the user based on the comparing step to steer the brain of the user towards a high performance cognitive state.

    摘要： According to various aspects, a new concept of Steady-State Visually Evoked Potential (SSVEP) based Brain-Computer Interface (BCI) is described where brain-computer communication occurs by capturing SSVEP induced by consciously imperceptible visual stimuli integrated into, for example, a virtual scene. These consciously imperceptible visual stimuli are able to convey subliminal information to a computer. In various embodiments, computer based operations can be mapped to visual elements with associated flickering stimuli, and induced SSVEP can be detected when the user focused upon them. In various embodiments, these visual elements can be introduced into existing display without any perceivable change to content being displayed.

    摘要： An object of the present disclosure is to provide a muscle condition measurement sheet that can quantitatively detect the amplitude and latency of an evoked electromyogram EMG or an evoked mechanomyogram MMG and correctly evaluate the state of activity of a muscle. A pair of stimulating electrodes and all myoelectric detection electrodes come into intimate contact with a body surface of a muscle, appearing on a back surface of an insulating sheet spaced at predetermined intervals; accordingly, the relative position between an electrical stimulation position and the myoelectric detection electrode is fixed and the amplitude and latency of the evoked electromyogram EMG can be quantitatively detected without depending on the stimulation position of an electrical stimulation signal.
