  • Title: Arousing feedback rectifies lapse in performance and corresponding EEG power spectrum.

    Journal: Annu Int Conf IEEE Eng Med Biol Soc; 2010; 2010():1792-5. PubMed ID: 21095934.
    Abstract:
    This study explores electroencephalographic (EEG) dynamics and behavioral changes in response to arousing auditory signals presented to individuals experiencing momentary cognitive lapses. Arousing auditory feedback was delivered to the subjects in half of the non-responded lane-deviation events during a sustained-attention driving task, which immediately agitated subject's responses to the events. The improved behavioral performance was accompanied by concurrent power suppression in the theta- and alpha-bands in the lateral occipital cortices. This study further explores the feasibility of estimating the efficacy of arousing feedback presented to the drowsy subjects by monitoring the changes in EEG power spectra.
