P300 BCI TASK
Unreviewed

P300-based brain-computer interface is a BCI paradigm relying on the online classification of event-related potentials. The user is required to attend specific target stimuli that are considered important and to ignore other, more frequent stimuli. The target stimuli elicit large P300 response that can easily be classified from epoched EEG. P300 BCI can rely almost on any type of stimuli, that are capable to evoke discernable ERPs - visual, tactile, auditory, etc. P300 BCI paradigm can be adopted for the gamification of ERP studies, as well as for communication in disabled patients.

IMPLEMENTATIONS of P300 BCI
OpenViBE is a software platform dedicated to designing, testing and using brain-computer interfaces. OpenViBE is a software for real-time neurosciences (that is, for real-time processing of brain signals). It can be used to acquire, filter, process, classify and visualize brain signals in real time. Since v2.2.0, OpenViBE also includes a tool for offline or batch analysis of large datasets. OpenViBE is free and open source software. It works on Windows and Linux operating systems.
Software suite for brain-computer interface research.

CONDITIONS

Experimental conditions are the subsets of an experiment that define the relevant experimental manipulation.

In the Cognitive Atlas, we define a contrast as any function over experimental conditions. The simplest contrast is the indicator value for a specific condition; more complex contrasts include linear or nonlinear functions of the indicator across different experimental conditions.

INDICATORS

No indicators have yet been associated.

An indicator is a specific quantitative or qualitative variable that is recorded for analysis. These may include behavioral variables (such as response time, accuracy, or other measures of performance) or physiological variables (including genetics, psychophysiology, or brain imaging data).
