|Attitude to Computers||Device: EEG Recording (Emotiv)||Early Phase 1|
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.

Experimental: Extraction of P300 ERPs
Extract P300 ERPs with Emotiv EEG headset
Device: EEG Recording (Emotiv)
Record EEG during auditory oddball paradigms:
Other Name: EEG recording
- Wilcoxon statistic (Area Under the Curve) [ Time Frame: T0+2h (end of each technique) ]
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.
