    Kenneth Campbell
    School of Psychology, University of Ottawa, Ottawa, ON, K1N 6N5, Canada
    Noise Health 12:137-53. 2010
    ..ERP studies will need to employ procedures that have greater ecological generalization; stimulus intensity needs to be lower, less abrupt, with much longer durations, and importantly, stimuli should be presented much less often...

    Merav Sabri
    School of Psychology, University of Ottawa, Ottawa, Canada
    J Sleep Res 11:123-7. 2002

    J Appl Physiol (1985) 104:958-75. 2008

  23. ncbi request reprint Is the failure to detect stimulus deviance during sleep due to a rapid fading of sensory memory or a degradation of stimulus encoding?
    Merav Sabri
    Department of Neurology, Medical College of Wisconsin, Milwaukee, WI 53226 3548, USA
    J Sleep Res 14:113-22. 2005
