- Quantitative characteristics of alpha and theta EEG activities during sensory deprivationK Iwata
School of Information Science, Japan Advanced Institute of Science and Technology, Hokuriku, Japan
Psychiatry Clin Neurosci 55:191-2. 2001..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...
- Differentiation of physiological states under sensory deprivationK Iwata
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...
- Fusing EEG and fMRI based on a bottom-up model: inferring activation and effective connectivity in neural massesJ Riera
Advanced Science and Technology of Materials, NICHe, Tohoku University, Aoba 10, Aramaki, Aobaku, Sendai 980 8579, Japan
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...
- Tissue Doppler-derived index of left ventricular filling pressure, E/E', predicts survival of patients with non-valvular atrial fibrillationH Okura
Division of Cardiology, Bell Land General Hospital, Sakai, Japan
Heart 92:1248-52. 2006..To investigate whether the ratio of early transmitral flow velocity (E) to early diastolic mitral annular velocity (E') predict prognosis in patients with non-valvular atrial fibrillation...
