Protocols and paradigms
38 termsSequence of frequent and infrequent stimuli to evoke specific potentials (e.g., P300).
A set of specific rules and procedures that define how the brain-computer interface (BCI) interacts with the subject and its environment.
A positive event-related potential caused by a cognitive process, appearing approximately 300 milliseconds after a stimulus.
Design frameworks or experimental approaches used to study brain responses and behavior in specific situations.
Observable and quantifiable bodily responses, particularly in neural activity patterns, due to perceived stressors, challenges, or strains.
A set of organized procedures or rules that are followed during the conduct of an experiment or data collection to ensure consistency and reliability in the results.
A slow build-up of electrical potential in the brain that precedes a person's voluntary movement. It's a key signal for BCIs that aim to predict movement intention.
Baseline acquisition without task engagement used for calibration and comparison.
n oscillation in electric or magnetic fields recorded over the sensorimotor cortex in specific frequency bands (typically 12-15 Hz).
An evoked potential in response to a tactile or proprioceptive stimulus.
A sequence of action potentials (spikes) that a single neuron produces over time.
An auditory evoked potential in response to repetitive audio stimuli. It is produced when the auditory system is stimulated at a rapid and constant rate, generating a continuous oscillatory response that matches the stimulus frequency.
A somatosensory evoked potential measured during selective attention tasks, generated by repetitive tactile stimuli (like mechanical vibration) at a constant frequency.
A visual evoked potential in response to repetitive stimuli with a light source flickering at a constant frequency.
A specific type of somatosensory evoked potential (SEP) that is evoked by tactile stimuli, such as touch or vibration.
A visual evoked potential that occurs at a relatively low rate, where the neural response appears as a discrete pulse for each individual stimulus.
An evoked potential in response to visual stimuli. They are specific patterns of electrical activity measured typically over the occipital region of the scalp, representing the brain's processing of the visual stimulus.
