Astringency: A more stringent definition

Abstract

Despite being an everyday sensory experience, the nature of astringency perception is not clear. In this issue of Chemical Senses, Schöbel et al. demonstrate that astringency is a trigeminal sensation in human, and astringents trigger a G proteincoupled pathway in trigeminal ganglion cells in the mouse. © The Author 2014.
