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

A measurement of the speed at which information is transferred from the subject to the processing unit.

A method in which subjects and/or experimenters are kept unaware of critical aspects to prevent bias in outcomes.

Experimental setup in which trials with the same condition are presented consecutively before switching.

A standard for organizing, annotating, and describing data collected during neuroimaging experiments.

A device that is surgically implanted into the brain

A direct communication pathway between the brain's neural activity and an external device. It functions by recording brain signals (often through electrodes), decoding those signals into commands using computer algorithms, and executing those commands to control a machine or prosthetic, often providing sensory feedback to the user to create a closed-loop system.

Rhythmic or repetitive patterns of neural activity in the brain. The modulation of these oscillations is a primary source of control signals for many BCIs.
