The mouth provides us with remarkable sensations.

We bite into, adeptly manipulate, and crunch foods without inflicting self-injury. Our dentition and supporting structures routinely tolerate extreme forces of mastication, yet they also allow us to discern minuscule changes in bite and unanticipated hard particulates in food. We hardly notice these forces in normal chewing function; however, if the teeth are damaged and the dental pulps become inflamed, their sensory input is altered and we begin to experience excruciating pain – the toothache.

In thinking about these phenomena, we also wonder: What makes the tongue and lips profoundly sensitive to touch? How do common components (i.e., sensory neurons) provide us with unique sensations from distinct tissues? What makes our mouth feel dry? Why is tooth pain exquisite? And how do we inherently “know” the position of our teeth, jaws, and tongue when we eat and speak?

The Emrick lab is interested in answering these types of questions (and others) by studying the molecules, cells, and circuitry of the sensory nervous system innervating the mouth, head, and neck. In essence, we want to understand how it all encodes oral and craniofacial information, contributes to normal tissue function, and ultimately drives reflexes and perceptions.

Scorpion toxin that targets 'wasabi receptor' may help solve mystery of chronic pain

Sept 13, 2019 | Dentistry Today

Researchers at UC San Francisco and the University of Queensland have discovered a scorpion toxin that targets the "wasabi receptor," a chemical-sensing protein found in nerve cells that's responsible for the sinus-jolting sting of wasabi and the flood of tears associated with chopping onions.
