Effects of Cognitive Factors on Perceived Odor Intensity in Adaptation/Habituation Processes: from 2 Different Odor Presentation Methods (2008)

Kobayashi, Takefumi, Sakai, Nobuyuki, Kobayakawa, Tatsu, Akiyama, Sachiyo, Toda, Hideki, Saito, Sachiko

The purpose of this study, which comprised 2 experiments, was to investigate cognitive effects on odor perception. An odor was presented using an olfactometer. In Experiment 1 (“continuous”...

Cross-Cultural Comparison of Data Using the Odor Stick Identification Test for Japanese (OSIT-J) (2006)

Kobayashi, Masayoshi, Saito, Sachiko, Kobayakawa, Tatsu, Deguchi, Yuichi, Costanzo, Richard M.

A new olfactory test, the odor stick identification test for Japanese (OSIT-J), has been developed in Japan. To determine if the OSIT-J would be effective cross-culturally, we administered the test...

Development of a Smell Identification Test Using a Novel Stick-Type Odor Presentation Kit (2006)

Saito, Sachiko, Ayabe-Kanamura, Saho, Takashima, Yasuhiro, Gotow, Naomi, Naito, Naomi, Nozawa, Takashi, ...

The odor identification is strongly influenced by the social and cultural factors; therefore, the odorants used in a smell identification test should be familiar to the test population. In addition,...

Laterality of Human Primary Gustatory Cortex Studied by MEG (2005)

Onoda, Keiko, Kobayakawa, Tatsu, Ikeda, Minoru, Saito, Sachiko, Kida, Akinori

We examined the laterality of the human gustatory neural pathway by measuring gustatory-evoked magnetic fields (GEMfs) and demonstrating the activation of the human primary gustatory cortex (PGC). In...

Gustatory Evoked Cortical Activity in Humans Studied by Simultaneous EEG and MEG Recording (2002)

Mizoguchi, Chie, Kobayakawa, Tatsu, Saito, Sachiko, Ogawa, Hisashi

Evoked potentials are widely used in clinical medicine for objective evaluation of sensory disturbances. However, gustatory evoked potentials (GEPs) have not been extensively studied due to lack of...

Decline in Taste and Odor Discrimination Abilities with Age, and Relationship between Gustation and Olfaction (2000)

Kaneda, Hirotaka, Maeshima, Kozue, Goto, Naomi, Kobayakawa, Tatsu, Ayabe-Kanamura, Saho, Saito, Sachiko

It is important to learn about changes in both taste and odor perceptions with increasing age, because the taste of foods we encounter in our daily life is strongly affected by their smell. This...

Perception of Everyday Odors—Correlation between Intensity, Familiarity and Strength of Hedonic Judgement (1999)

Distel, Hans, Ayabe-Kanamura, Saho, Martínez-Gómez, Margarita, Schicker, Ina, Kobayakawa, Tatsu, Saito, Sachiko, ...

In this study, 40 Japanese, 44 German and 39 Mexican women were presented with 18 everyday odorants. They were asked to rate them for intensity on a six-point scale from not detectable to very...

Spatio-temporal Analysis of Cortical Activity Evoked by Gustatory Stimulation in Humans (1999)

Kobayakawa, Tatsu, Ogawa, Hisashi, Kaneda, Hirotaka, Ayabe-Kanamura, Saho, Saito, Sachiko

Gustatory activated regions in the cerebral cortex have not been identified precisely in humans. In this study we recorded the magnetic fields from the brain in response to two tastants, 1 M NaCl and...

Differences in Perception of Everyday Odors: a Japanese-German Cross-cultural Study (1998)

Ayabe-Kanamura, Saho, Schicker, Ina, Laska, Matthias, Hudson, Robyn, Distel, Hans, Kobayakawa, Tatsu, ...

There is a growing appreciation that experience with odors may strongly influence their perception. To further investigate this, the responses of 40 Japanese and 44 age-matched German women to...
