Multilayer network mapping complex neural patterns to behavioral outputs.

Techniques used specifically to reduce background noise in neural data and improve signal quality.

A BCI system that uses brain signals that depend on muscle activity (such as eye movements or facial muscles) to generate the necessary signals for control.

A method for assessing long-range temporal correlations and self-similarity in non-stationary EEG signals.

3D imaging of brain activity using near-infrared light and advanced reconstruction algorithms.

Simplifying neural data while preserving essential information (e.g., using PCA or t-SNE).

Modern electrodes designed to function without conductive gel, making direct contact with the scalp. They offer significantly faster and cleaner setup, a high priority for practical and consumer BCI systems, though they can present challenges in comfort and signal stability.[35, 36]

The potential for neurotechnologies to be used for either beneficial or harmful purposes, intentionally or otherwise.

Adjustment of stimulation frequency parameters in real-time to modulate user perception or control outcomes.

Experimental design carried out in naturalistic, real-world settings rather than in controlled laboratories.

A device embedded with multiple electrodes to record the electrical activity of the brain from the scalp.

A specific type of transducer that converts electrical signals into physical actions

Invasive recording of brain activity from the cortical surface.

A specific type of transducer that establishes electrical contact with a physical part of a circuit, acting as the interface between the biological medium (brain) and the electronic system.

The electrical resistance and reactance at the interface between the electrode and the skin, which affects signal quality and stability.

A graphic record of the variation with time of voltages taken from electrodes on the scalp, whose positions are specified according to a standard system.

A graphic record of the variation with time of voltages produced by the electrical activity of muscle fibers, recorded via electrodes placed on the skin or inserted into the muscle.

Technique for recording electrical activity in peripheral nerves, complementing central modalities.

A transient, intense response to a specific stimulus that typically has a clear cause or trigger. It is the result of thoughts, feelings, actions, psychological states, and learned experiences in response to a stimulus or changes in a contextual environment.

Minimally invasive neural implants introduced via blood vessels to interface with the brain without open surgery.
