For the recording of gustatory evoked responses, the tip of a stimulator is pressed vertically on one side of the tongue until the trigger pulses are generated by a switch attached to the bottom of the stimulator. According to our results, no detectable response was observed in the absence of taste. The positive waves were distinguishable by using the(More)
Chronic pain refractory to non-steroidal anti-inflammatory drugs (NSAIDs) is a major problem and drugs for such pain are needed. Many studies suggest that transient receptor potential vanilloid type 1 (TRPV1) is associated with NSAID-refractory chronic pain. Therefore, we investigated the involvement of TRPV1 in NSAID-refractory chronic pain using(More)
We previously reported emergence and disappearance of circadian molecular oscillations during differentiation of mouse embryonic stem (ES) cells and reprogramming of differentiated cells, respectively. Here we present a robust and stringent in vitro circadian clock formation assay that recapitulates in vivo circadian phenotypes. This assay system first(More)
Evoked potentials to taste stimulations were discussed. New our technique of objective measurement of gustatory function by an evoked potential technique will be introduced. As a result, introduction of taste solution on the tongue innervated by facial nerve in normal subjects resulted in positive responses. Absence of taste solution did not resulted in the(More)
Transient receptor potential vanilloid 1 (TRPV1) activation in peripheral sensory nerve is known to be associated with various pain-related diseases, thus TRPV1 has been the focus as a target for drug discovery. In this study, we characterized the pharmacological profiles of(More)
In our study, we explored the influence of blast method introduction of odorant on evoked response. In normal patients, no detectable response was observed in the absence of an odor, and introduction of an odorant at the end of inspiration or during expiration did not result in any detectable positive response. In anosmic patients, glacial acetic acid,(More)
