    - One subject, two acquisition runs of 6 minutes each
    - Subject stimulated binaurally with intra-aural earphones
      (air tubes+transducers)
    - Each run contains:
        - 200 regular beeps (440Hz)
        - 40 easy deviant beeps (554.4Hz, 4 semitones higher)
    - Random inter-stimulus interval: between 0.7s and 1.7s seconds, uniformly
      distributed
    - The subject presses a button when detecting a deviant with the right
      index finger
    - Auditory stimuli generated with the Matlab Psychophysics toolbox
