The purpose of this study is to compare three different techniques of EEG recording for extraction of P300 Evoked Related Potentials (ERPs).
Brain Computer Interface (BCI) are used to restore control and communication in patient with severe disabilities such as Locked In Syndrome (LIS) patients.
The aim of this study is to identify the most relevant recording technique for extraction of P300 ERPs in EEG signals. Three different electrodes (needle, standard ,silver) will be simultaneously compared in a prospective design in 10 healthy volunteers, as suggested by principal investigator.

| Wilcoxon statistic (Area Under the Curve) | An Linear Discriminant Analysis (LDA) will be used to discriminate target and Algorithm performance (Wilcoxon statistic) for discrimination between occurrent and non-occurrent stimuli. Signals will adequately be pre-processed: denoised and spatialy filtered (xDAWN). The Area Under the Receiver Operator Characteristic Curve (AUC) also called wilcoxon statistic will be used to identify the signals of best quality. | T0+2h (end of each technique) |
