Primary Outcome Measures:
  • Change in N-back [ Time Frame: Day 1 and Day 2 for each of the 5 Period ]
    The N-back test is both sensitive to SD in healthy volunteers and this test belongs to ADNI cognitive battery which is validated in Alzheimer's disease patients,considered as primary endpoint.

Secondary Outcome Measures:
  • Other cognitive assessments [ Time Frame: Day 1 and Day 2 for each of the 5 Period ]
    CANTAB Battery, Memory Rey Auditory Verbal Learning Test (AVLT), Digit Span Test, Verbal Fluency task

  • fMRI [ Time Frame: Day 1 and Day 2 for each of the 5 Period ]
    Resting fMRI, fMRI Memory task

  • Rest-EEG and P300 after auditory-ball paradigm Rest-EEG and P300 after auditory-ball paradigm Rest-EEG and P300 after auditory-ball paradigm [ Time Frame: Day 1 and Day 2 for each of the 5 Period ]
