Abstract/OtherAbstract:

We asked subjects to sniff a bottle containing distilled water and to say whether they felt a cooling or warming sensation in the nasal cavity. Odorless food coloring was added to three of these bottles so as to obtain one yellow, one green, one red and one colorless solution. Subjects were presented with each bottle four times under free viewing conditions or while blindfolded, and each nostril was tested separately. Although no thermal stimulus was present, subjects reported thermal sensations, but only under free viewing conditions. The nature of these sensations depended on the color of the solution, with green inducing cooling and red warming sensations. It also depended on which nostril was tested, with warming sensations evidenced only when the left nostril was tested, and cooling sensations only when the right nostril was tested. It is the first time color has been reported to induce nasal thermal sensations in the absence of thermal stimuli. These results are therefore entirely new. Furthermore, they suggest that thermosensory processing and judgment may depend on lateralized processes in the human brain. |
