Further study details as provided by Centre d'Investigation Clinique et Technologique 805:

Primary Outcome Measures:
  • 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.

Enrollment: 10
Study Start Date: June 2012
Study Completion Date: July 2012
Primary Completion Date: July 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Extraction of P300 ERPs
Extract P300 ERPs with Emotiv EEG headset
Device: EEG Recording (Emotiv)

Record EEG during auditory oddball paradigms:

  • with Emotiv EEG headset EMOTIV CAP (see
  • with 3 electrodes : 3 different types of electrodes at the time (needle, cupule 5mm, cupule 10mm)
Other Name: EEG recording

Detailed Description:

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.
