Outline of Final Research Achievements

The effects of air-diluted Wasabi odor (allyl isothiocyanate: 3.5-20PPM) on sleeping humans with and without hearing disabilities were monitored. The mean latencies between arrival of the odor at the bed and pressing the button by the bed were approximately 21 sec for deaf subjects and 45 sec for hearing subjects, respectively in sleep stage 2. Observed quick response to the odor, which stimulates trigeminal somatosensory system, in early-onset deaf subjects probably reflects neuroplastic changes, namely, involvement of original auditory area in temporal lobe for somatosensory information processing. The findings of this research was applied to fire alarm for the deaf and patented. Researcher gave several lecture presentations in relation to the Ig Nobel Prize or innovation.
