This article discusses halitosis, and disorders of taste, orofacial movement or sensation.

Many languages have a word class whose speech sounds are linked to sensory experiences (sound symbolism). Here we investigated sound symbolism in taste. Specifically, we performed psychological experiments to study the relationship between phonemes of Japanese sound symbolic words and emotional evaluations of objects in taste. In the experiment, when participants drank something, they were aske...

The Indian herb Gymnema sylvestre has been used in traditional Ayurvedic medicine for 2000 years, most recently for the treatment of diabetes. Loose leaf Gymnema sylvestre can be prepared as a tea and will impair the ability to taste sugar by blocking sweet receptors on the tongue. This report describes a laboratory exercise easily applied to an undergraduate neuroscience course that can be use...

The sense of taste is a specialized chemosensory system dedicated to the evaluation of food and drink. Despite the fact that vertebrates and insects have independently evolved distinct anatomic and molecular pathways for taste sensation, there are clear parallels in the organization and coding logic between the two systems. There is now persuasive evidence that tastant quality is mediated by la...

The purpose of this study was to evaluate quantitatively the taste of the various total enteral nutrients marketed in Japan using human gustatory sensation tests and an artificial taste sensor. In the human gustatory sensation test, four basic taste intensities (sweetness, saltiness, sourness, and bitterness), as well as 15 kinds of palatability scales, were evaluated according to the semantic ...

Intravital microscopy is a powerful tool in neuroscience but has not been adapted to the taste sensory organ due to anatomical constraint. Here we developed an imaging window to facilitate microscopic access to the murine tongue in vivo. Real-time two-photon microscopy allowed the visualization of three-dimensional microanatomy of the intact tongue mucosa and functional activity of taste cells ...

As nontraditional model organisms with extreme physiological and morphological phenotypes, snakes are believed to possess an inferior taste system. However, the bitter taste sensation is essential to distinguish the nutritious and poisonous food resources and the genomic evidence of bitter taste in snakes is largely scarce. To explore the genetic basis of the bitter taste of snakes and characte...

OBJECTIVE The primary objective was to assess the warming sensation caused by IFF Flavour 316282 in a syrup used for short-term treatment by patients suffering from nasal congestion and mild to moderate body pain, headache, fever or sore throat associated with an upper respiratory tract infection. METHODS A single cohort, single treatment arm, open-label study. Subjects received one 30 mL dos...
