323 termsA 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.
Officially Verified Term A brain-computer interface is a system that measures brain activity and converts it in (nearly) real-time into functionally useful outputs to replace, restore, enhance, supplement, and/or improve the natural outputs of the brain, thereby changing the ongoing interactions between the brain and its external or internal environments. It may additionally modify brain activity using targeted delivery of stimuli to create functionally useful inputs to the brain.
Fluorescence-based method monitoring neuronal activity via calcium ion concentration changes.
Initial data recording used to train algorithms and align user-system parameters.
Non-contact EEG method utilizing capacitive sensors, enhancing user comfort and ease of setup.
The pathway through which the brain signal is collected, transmitted, and processed
A machine learning algorithm that learns to assign a label (e.g., move left or select letter B) to a pattern of neural activity. Common examples include
An auditory evoked potential in response to a click stimulus, which is a brief, sharp sound used in auditory testing.
A study involving multiple subjects that assesses the efficacy of a proposed intervention
A specific time period during which a subject receives an intervention or undergoes an assessment or both.
A characteristic of a system whose control action is dependent on the output of the task and its deviation from a reference or ideal state.
The amount of mental effort and concentration required from the user to operate the BCI. A primary goal of BCI design is to minimize this load.
Protecting neural data from cyberattacks, manipulation, or information leaks.
a BCI system that combines brain signals from several people in order to perfrom a task.
