From: The challenge of controlling an auditory BCI in the case of severe motor disability
Offline classification results of ATTENDED versus IGNORED stimuli with and without ICA correction. Offline BCI simulations with 15 channels, for healthy subjects (a) and patients (b). Boxplots filled with light gray stand for accuracy results with no pre-processing of the data, except filtering. Boxplots filled with dark gray stand for the condition where the signal was preprocessed with ICA, removing blinks, saccades and a DC component. Stimulations: Total: Pool of responses to all stimuli, STD: Pool of all responses do standards, DEV: Pool of all responses to deviants, YES: Pool of all responses to « yes», NO: Pool of all responses to « no»
