Integration within VR or XR environments for enhanced engagement.

impedance is the measure of opposition to electrical current flow between an electrode and the scalp. Low impedance is crucial for acquiring clean, high-quality brain signals.

A BCIsystem that does not rely on the brain's natural output pathways (such as peripheral nerves and muscles). Control is generated entirely through mental activity without requiring physical

A statistical method used to separate a multivariate signal into its independent, constituent sources. In BCI, it is most commonly used for artifact removal, such as separating eye blinks and muscle noise from the underlying brain signals.

Preservation of confidentiality, integrity and availability of information

Ensuring users and research participants are fully aware of risks, benefits, and study details, providing their conscious agreement.

Imaging method detecting heat patterns from the scalp to infer underlying brain blood flow and metabolic activity.

A specialized amplifier that accurately amplifies the small differential signals from electrodes while rejecting common-mode noise.

The period of time between the end of one stimulus and the start of the next stimulus

The period of time between separate trials within a session.

Variability or measurements compared between different subjects in a study.

A graphic record of the variation with time of voltages taken from electrodes placed onto or deeply inserted into the brain to directly record electrical activities of the brain through sensors.

Variability or measurements taken within the same subject across different times or conditions.

A BCI system in which neural activities are recorded using a surgically implanted device. It involves placing sensors directly into the brain tissue to capture high-resolution signals from individual neurons.
