Transient gamma-band response is dissociated from sensory memory as reflected by MMNHirooki Yabe
Department of Neuropsychiatry, Hirosaki University School of Medicine, Zaifu cho 5, Hirosaki 036 8562, Japan
Neurosci Lett 380:80-2. 2005..The findings indicate that the brain process underlying the transient gamma-band response should be dissociated from the sensory memory function...- Organizing sound sequences in the human brain: the interplay of auditory streaming and temporal integrationH Yabe
Department of Neuropsychiatry, Hirosaki University School of Medicine, 036 8562, Hirosaki, Japan
Brain Res 897:222-7. 2001..This result shows that auditory streaming takes precedence over the processes of temporal integration... - Automatic discriminative sensitivity inside temporal window of sensory memory as a function of timeH Yabe
Department of Neuropsychiatry, Hirosaki University School of Medicine, Hirosaki 036 8562, Japan
Brain Res Cogn Brain Res 12:39-48. 2001..Thus, mismatch process is triggered at the moment of change but still lasts after the detection of deviation. In other words, both standard and deviant stimuli are treated as a unitary event within a TWI... - Time may be compressed in sound representation as replicated in sensory memoryHirooki Yabe
Department of Neuropsychiatry, Hirosaki University School of Medicine, Hirosaki 036 8562, Japan
Neuroreport 16:95-8. 2005..The main result was that the encoded period from early to late omitted segment was shorter than the actual one, suggesting that time may be compressed in the sound representation... - Sound perception affected by nonlinear variation of accuracy in memory traceHirooki Yabe
Department of Neuropsychiatry, Hirosaki University School of Medicine, Hirosaki 036 8562, Japan
Neuroreport 15:2813-7. 2004..In sum, the discriminative sensitivity nonlinearly declined toward the end of the TWI, suggesting that the time-wise accuracy of the neural trace nonlinearly varies in sensory memory... - Event-related desynchronization during an auditory oddball taskT Sutoh
Department of Neuropsychiatry, Hirosaki University School of Medicine, Zaifu cho 5, Hirosaki, Japan
Clin Neurophysiol 111:858-62. 2000..The present study addressed what kind of mental processes would be presented by the event-related desynchronization (ERD) relevant to the stimuli of an auditory oddball count task... - Somatosensory automatic responses to deviant stimuliN Shinozaki
Department of Neuropsychiatry, Hirosaki University School of Medicine, Zaifu cho 5, Hirosaki 036, Japan
Brain Res Cogn Brain Res 7:165-71. 1998..These findings suggest that the somatosensory change-related positivity is probably generated not by activation of new afferent elements but by a detection of change in a process of comparison with sensory memory... 
Memory trace dependence on number of stimuli in magnetic mismatch negativityTakashi Matuoka
Department of Neuropsychiatry, Hirosaki University School of Medicine, Hirosaki, Japan
Neuroreport 19:1003-7. 2008..When the number of standard stimuli increased, MMNm latency significantly shortened and the MMNm amplitude showed no significant change. Thus, the developmental effects on memory trace may differ between MMNm amplitude and MMNm latency...- [Study of sensory memory reflected by mismatch negativity and its clinical application]Hirooki Yabe
Department of Neuropsychiatry, Hirosaki University School of Medicine
Seishin Shinkeigaku Zasshi 106:1-16. 2004..For example, reduced amplitude of MMN is a robust finding in schizophrenia. Some basic MMN studies and their promising clinical applications are described here... - Automatic auditory information processing in sleepT Nashida
Department of Neuropsychiatry, Hirosaki University School of Medicine, Japan
Sleep 23:821-8. 2000..Using the same experimental condition, we examined whether or not MMN amplitude was influenced by long-term stimulus presentation (80min.) and by vigilance level (Experiment 2)... - The development of memory trace depending on the number of the standard stimuliTakashi Matuoka
Department of Neuropsychiatry, Hirosaki University School of Medicine, Hirosaki, Japan
Clin EEG Neurosci 37:223-9. 2006..These findings indicate that both frontal and temporal MMN components reflect the development of memory trace depending on the number of standard stimuli... - Altered pharmacokinetics and metabolism of valproate after replacement of conventional valproate with the slow-release formulation in epileptic patientsTsuyoshi Kondo
Department of Neuropsychiatry, Hirosaki University School of Medicine, Japan
Pharmacol Toxicol 90:135-8. 2002.... - Spectrotemporal window of integration of auditory information in the human brainNaoko Shinozaki

Department of Neuropsychiatry, School of Medicine, Hirosaki University, Japan
Neurosci Res 43:23-9. 2002..The results suggest that the neural activities in hippocampal regions are involved with the generation of gelastic seizures with a sense of mirth and those in the cingulate might be associated with the motor act of laughter... - Early contingent negative variation (CNV) shows a small symmetrical negativity in a somatosensory paradigmYasuharu Sato
Department of Neuropsychiatry, Hirosaki University School of Medicine, Hirosaki, Japan
