    ..As a result, the mean duration of the theta wave is found to be longer than that of the alpha wave. This result could be useful to disclose physiological processes during SD...

    School of Information Science, Japan Advanced Institute of Science and Technology, Hohuriky, Japan
    Methods Inf Med 39:168-70. 2000
    ..Such dissociation between states classified by EEG and HRV dynamics frequently takes place during SD. These findings suggest the peculiarity of the physiological state during the SD distinct from sleep and wakefulness...

    Philos Trans R Soc Lond B Biol Sci 360:1025-41. 2005
    ..In this context, the concepts of activation and effective connectivity are carefully revised. This new approach permits us to examine and discuss some future prospects for the integration of multimodal neuroimages...
