Abstract: An apparatus and method for monitoring a driver using a brain wave signal of the driver are disclosed. The monitoring method includes collecting a brain wave signal for a driver in a vehicle for a predetermined time, determining the driver's state by analyzing the brain wave signal collected for the predetermined time, and controlling an operation of the vehicle on the basis of the determined driver's state.

Abstract: Method and apparatus for detecting an evoked potential in a physiological signal of a user, in response to the generation of a sensory stimulation signal played by a human machine interface intended for the user. The sensory stimulation signal is periodic and adjustable in frequency. For a given sensory stimulation signal, the frequency of the given signal is adjusted to a first frequency, and then a latency in the user's reaction between the moment the given signal is generated and the moment the evoked potential is detected when such detection occurs is measured. If the latency is lower than a threshold, information is stored according to which the first frequency is attributable to a sensory stimulation signal. Otherwise, the method is repeated with a second frequency in place of the first frequency, the second frequency being different from the first frequency.

Abstract: A novel method for using the widely-used electroencephalography (EEG) systems to detect and localize silences in the brain is disclosed. The method detects the absence of electrophysiological signals, or neural silences, using noninvasive scalp electroencephalography (EEG) signals. This method can also be used for reduced activity localization, activity level mapping throughout the brain, as well as mapping activity levels in different frequency bands. By accounting for the contributions of different sources to the power of the recorded signals and using a hemispheric baseline approach and a convex spectral clustering framework, the method permits rapid detection and localization of regions of silence in the brain using a relatively small amount of EEG data.

Abstract: Disclosed herein are methods and systems for transient-based decoding of neural signals. In one aspect, a device such as a brain-computer interface (BCI), includes at least one processor configured to receive a plurality of neural signals from a subject. The at least one processor can detect, from the plurality of neural signals, first neural activity unique to a first defined temporal window corresponding to an onset phase of an intended action of the subject. The at least one processor can detect, from the plurality of neural signals, second neural activity unique to a second defined temporal window, occurring after the first temporal window and corresponding to an offset phase of the intended action. The at least one processor can generate at least one output indicative of the intended action, responsive to detecting at least one of the first neural activity or the second neural activity.

Abstract: Methods, systems, apparatus, and non-transitory computer readable media are disclosed utilizing brain-computer interfaces (BCIs). Various embodiments are disclosed to allow a user to directly select multiple-choice answers, to provide motorized wheelchair controls, and to allow a user to play a game via the BCI. When used in a cognitive assessment test, embodiments include the administration of unmodified standardized tests with results in the same or a similar format as those taken without a BCI. Various embodiments are disclosed to improve the accuracy of BCI test administration using a three-step process for each test question, which includes determining whether the user intends to select an answer, monitoring user brain activity to determine a selected answer, and verifying the selected answer. In addition, the selected answer may be verified by monitoring user brain activity in accordance with a hold-release process to determine whether a user intends to initiate a state change.
