An evoked potential in response to audio stimuli. It represents the brain's processing of auditory information and can be observed as specific patterns of electrical activity over the auditory cortex, typically captured via electrodes placed on the scalp.

Information relayed through sounds or tones to guide or notify the user about system events or control performance.

The imagination of the generation of sounds without any external auditory stimulus.

Using neural stimulation to enhance or improve cognitive or motor abilities

A reality-based interactive technology in which digital content is overlaid onto the real world to enhance the user's perception of and interaction with reality.

A neural network that compresses and reconstructs brain data for feature extraction or noise reduction purposes.

A statistical approach where signal values are predicted using weighted sums of prior values, useful for characterization of rhythms.

Unwanted power in certain frequency bands (e.g., excessive line noise or artifact power) degrading signal quality.

EEG feature representing signal power within standard frequency bands (delta, theta, alpha, beta, gamma).

A filter that blocks frequencies within a specific range.

A reference period where no experimental manipulation occurs; used to compare the effects of interventions.

A probabilistic model that estimates the likelihood of specific mental states occurring.

Probabilistic approach for updating the probability estimate for a hypothesis as more neural data becomes available.

Ensuring that BCI development leads to real benefits for individuals and society.

Systematic error or deviation from true values that affects experimental validity or measurement accuracy.

A BCI system that combines two functions: reading brain signals to control an external device, and writing signals (stimulation) back to the brain to provide sensory feedback.

The ability of a material used in the brain-computer interface to perform its intended function without causing any adverse effects to the surrounding biological tissues of the user.

A process of gaining greater awareness of various physiological functions of the user's own body by using monitoring devices that provide real-time information.

The use of EEG signasls a security biometric for the purpose of authentication or identification
